  • And, lastly, several performance improvements thanks to customer feedback.

* Note that some features are only available in certain editions of Curio. Please see the release notes for details.

Curio 16 runs on macOS 10.14 Mojave through macOS 11 Big Sur on Intel or Apple silicon.

Check out the release notes for all the details and, if you want even more information, the complete documentation is online.

If you’ve purchased a Curio 15 traditional license from our website then this is a free upgrade for you. Check for updates should find it automatically. For customers on older traditional licenses, discounted upgrades are available.

For those that subscribe to Curio via the Mac App Store, it should automatically download the new version to your Mac shortly.

Announcing Curio 15!

Curio 15 is here! πŸŽ‰

We're super excited about this latest release of Curio which includes several new features customers have been requesting.

What’s New in Curio 15?

  • Custom data keys and values can now be associated with your figures.

  • Markdown image syntax is now supported in Curio text figures.
  • Markdown highlight syntax is now supported in Curio text figures.
  • Markdown emoji cheat codes are now supported in Curio text figures.
  • Show your presentation within a window, which can come in handy if sharing via conferencing software.
  • Presentation mode now supports Touch Bar controls, which can come in handy if controlling your presentation via a Sidecar-connected iPad. 
  • Use appearance themes to customize the look of your Curio.
  • Curio documentation is now completely online.
  • Loads of other other tweaks, fixes, and optimizations.

* Note that some features are only available in certain editions of Curio. Please see the release notes for details.

Curio 15 runs on macOS 10.14 Mojave through macOS 11 Big Sur on Intel or Apple silicon.

Check out the release notes for all the details and, if you want even more information, the complete documentation is now online.

For existing customers with traditional licenses, discounted upgrades are available to Curio 15 Professional, Standard, and Core.

For those that subscribe to Curio via the Mac App Store, it should automatically download the new version to your Mac shortly.

Changes to Traditional Licenses

Our other big news is, starting with today's release of Curio 15, traditional licenses now include a free year of major and minor updates!

The full details are here but, in short, instead of massive annual releases containing thousands of changes, we're shifting to a continuous stream of major releases appearing every 1-3 months.

For this reason you will notice that Curio 15 isn't as massive as our prior major version releases. Curio 14 was such an arduous, prolonged release, that we faced either postponing Curio 15 for 6 or more months, or shifting to a new approach we've long been considering.

With a year of free updates you get a constant stream of new major features appearing every few months, instead of annual massive releases. This means Curio 16 is right around the corner, then Curio 17, then Curio 18, etc. Major features appearing as they are developed instead of queuing up for a monolithic release a year in the future.

At the end of your year of free updates, your Curio app continues working normally – it does not expire or deactivate – however, you will no longer receive app updates. Whenever you wish, you can purchase an upgrade license to update to the latest version and receive another year of app updates.

Please read all the details behind this change in our new Curio Traditional License FAQ.

How does this impact Curio Subscribers?

Curio subscribers via the Mac App Store are always on the latest release of Curio. With this change the only difference is that major features will be appearing much more frequently instead of dropping once a year. Enjoy!

More Amazing Features Coming Soon!

We have some fantastic major features lined up for the the upcoming major releases so stay tuned!

Going Universal

I thought I'd jot down a brief history of going universal with Curio...

PowerPC β†’ Intel

Apple shifted from PowerPC to Intel on January 10, 2006 with the Mac OS X Tiger 10.4.4 release. This also introduced the concept of universal binaries to the Mac audience, where a single app contained native code for both PowerPC and Intel architectures.

I remember purchasing a first generation Intel MacBook Pro immediately after that announcement to work on Curio 3's universal transition. We released the Curio 3.1 PowerPC+Intel universal build on March 29, 2006. 

A relatively quick code transition process, although mainly complicated due to the "endian" differences between the two architectures impacting some low-level code, and because the tools back then were not so robust.

Apple continued supporting PowerPC through Leopard (10.5) but dropped it with Snow Leopard (10.6) which came out August 28, 2009. 

Curio continued supporting Leopard and therefore PowerPC chips, all the way until Curio 8.0 released on October 11, 2012 when we made macOS Lion (10.7) our minimum requirement.

Intel β†’ Apple Silicon

And now we're going universal again with Curio 14.4 with support for Intel and Apple silicon architectures on macOS 11 Big Sur (11.0). This means Curio 14 natively supports Apple's new generation of Macs using their astounding M1 chip, while still supporting Intel Macs.

Given that Curio 14 has a 3x larger codebase than our earlier universal transition, with a coding timeline that stretches back 18 years, this was, shockingly, a much faster process I believe for several key reasons:

  1. With every major release of Curio and Xcode, we do our best to tackle any new compiler warnings and to keep up with Apple's aggressive annual deprecation strategy, where they drop support for prior frameworks, classes, and technologies and promote newer techniques. We document many of these changes at the bottom of our release notes (see 141312, ...). Often these behind-the-scenes code refactorings can take weeks and can be a frustrating experience as previously working code is rewritten for a new technique or class. However, while these changes don't bring new features to our customers, they presumably make our code more resilient to major Apple transitions like this.
  2. Apple's much-improved tools. Xcode and its many code analyzers, runtime sanitizers, thread checkers, and performance profilers are a tremendous help in making sure our code is clean.
  3. We were fortunately eligible for Apple's Developer Transition Kit which allowed us to compile, test, and release our universal builds before Apple's new M1 Macs started shipping.
  4. And, of course, Apple did an outstanding job making sure their Apple silicon-based macOS was rock solid, even in its initial release. A huge shout-out to that team!

As I write this, we have an M1 MacBook Air on order, hopefully arriving within a few days. We'll continue testing on this shipping hardware to make sure Curio 14 is shipshape on this new architecture!

One Build

It's exciting to release a single build of Curio that supports so many significant macOS releases and architectures:

  • Mojave (10.14) on Intel, which is the last one that supports 32-bit apps which many customers may still need,
  • Catalina (10.15) on Intel, which is the most popular macOS currently,
  • Big Sur (11.0) on Intel and Apple silicon, which is the beginning of the macOS 11 era.

It's also exciting to see the Mac itself go through so many transitions, from Motorola, to PowerPC, to Intel, and now to custom Apple chips. These evolutionary steps, plus the transition to macOS 11, gives the Mac ecosystem a new thrill and excitement that has been missing the past few years.

Go Macintosh!

PS: If you're a current customer still on an older version of Curio, purchase a discounted upgrade to Curio 14 and you'll be ready for both macOS 11 and the Apple silicon generation!

PPS: Curiota is universal as well!

Curio 14.4, Big Sur, Apple silicon!

Curio 14.4 is out with two huge headline features:

  • Support for macOS Big Sur!
  • Support for the new generation of Macs using Apple silicon!

macOS Big Sur

Apple is taking an evolutionary leap from macOS X to macOS 11 Big Sur! Its brilliant new interface brings new life to the Mac. 

macOS Big Sur also brings some updates to its underlying frameworks which allows us to offer new functionality in Curio 14.4 including local PDF generation of math equations, Grab Web Archive, Organizer web view support for a find bar, support for macOS Big Sur's new unified toolbar style, and a nifty new app icon that matches the look of Apple's bundled macOS Big Sur app icons.

Apple Silicon

Curio is now built as a universal binary, which means it runs natively on Intel and on the new generation of Macs powered by Apple's amazing M1 chip

Most importantly this means it is not running under the macOS Big Sur Rosetta translation environment (aka emulation) on Apple silicon Macs, which could have performance and/or compatibility issues 

Plus More

And of course there are a slew of other tweaks and fixes, thanks to feedback and requests from customers.

Updating to Curio 14.4

See the release notes for full details on everything in Curio 14.4.

Curio 14.4 is a free update for Curio 14 customers:

  • For customers who downloaded Curio from our website, you should see the update available notice during its daily check, or you can choose Curio > Check for Updates to force a check.
  • For customers who downloaded Curio from the Mac App Store, it should get updated automatically by macOS or you can use the Mac App Store app to force an update.

Enjoy the new release! 

Curio 14.3

We just released another update to Curio 14 with tons of requested features and changes!

  • Smarter support for markdown files dragged into idea spaces.
  • Optional support for markdown auto detection.
  • Local Library + Curiota notes integration improvements.
  • Copy As Hyperlink support for selections within Organizer PDF documents.
  • Share > Selected Figures > Export As > Assets.
  • New Status shelf Live Export Sort By option.
  • More intuitive Natural Size handling.
  • Several new inline variables.
  • Plus many more tweaks and fixes.

Full details here in the release notes:


Curio 14.2

Another update to Curio 14 with more productivity enhancements!

  • Custom titles for journal entries.
  • Layer visibility tricks.
  • Apply style submenus for faster access.
  • Localized date text.
  • Tweaks and fixes.
  • More efficient image preview loading and faster rendering!
  • Plus some initial macOS Big Sur compatibility tweaks.

Full details here in the release notes:


Curio 14.1 tweaks

We rolled out Curio 14.1 over the weekend with a bunch of nifty features, tweaks, and fixes:

Deep Hyperlinks
Copy As Hyperlink can now encode deeper link information about the selected figure. 

  • If you've selected a range of text in a text figure, or
  • If you've selected a range of text on a page in a PDF figure, or
  • If you're playing back a video or audio figure on the idea space,

... then when you choose Copy As Hyperlink, the link will include those specific details.

Clicking the resulting hyperlink, whether it's in Curio or another application, will tell Curio to jump to that project, that idea space, and that figure, then set the selection of that text figure or PDF figure, or start playing back the media at that location.

Hyperlinks created using our AppleScript interface, like for our integration with Hook, will automatically pick up these deeper link details if the selected figure is being edited or played.

Retina Images During HTML and Image Export
During HTML and Image export on Retina systems, the resulting images are now 144 dpi Retina instead of 72 dpi, which results in much sharper images!

Additional Enhancements
Several other tweaks are in this release including significant improvements when drawing orthogonal lines, nicer link text when adding a Hook URL as a reference or when pasting a Hook URL onto an idea space, plus much more!

And Fixes, Too...
And Curio 14.1 includes fixes for issues reported since Curio 14's original release, including some Catalina+iCloud oddities.

See the release notes for full details!

Curio 14 from our website should see the update automatically during its daily check, or you can choose Curio > Check for Updates to force a check. Curio from the Mac App Store should have already downloaded and installed the update automatically.

Curio 14 is here!

We're excited to introduce everyone to Curio 14! πŸŽ‰

What’s New in Curio 14?
  • An integrated journalling system for meetings or class notes, all neatly organized and sorted automatically;
  • a dynamic Table of Contents list or mind map figure;
  • a new layers popover providing drag-and-drop reordering and visibility restrictions;
  • automatic figure spacing as figures grow or shrink in size;
  • improved Spread PDF across rows and columns creating a matrix of pages;
  • markdown rendering refinements;
  • brush and pen improvements including support for iPad+Apple Pencil sketching;
  • numerous figure and collection features;
  • improved DEVONthink integration; major performance enhancements;
  • code updates to better support Apple’s latest macOS releases
  • plus dozens of other features and improvements.

* Note that some features are only available in certain editions of Curio.

Our What's New section on the website provides a great overview of the new features or you can check out our always-thorough Curio 14 Release Notes to get the details.

We packed in loads of new productivity tools, scores of feature enhancements (many based on customer feedback!), and an insane number of code updates to make Curio more useful, robust, optimized, and  future-proof.

Curio 14 requires macOS Mojave or Catalina.

For existing customers, discounted upgrades are available to Curio 14 Professional, Standard, or Core.

For those subscribing to Curio via the Mac App Store, the update should be pushed to Apple's servers very soon.

We're thrilled to finally bring Curio 14 to everyone! Enjoy!

Working away

To say these are interesting times is an understatement.

For those that have inquired, we're all safe and healthy hunkered down here in our home. One doing virtual work, one doing virtual school, one starting virtual school soon, plus me continuing the work-at-home trend as I have for 18 years so far.

The news regarding the recent Omni Group layoffs was a shock. So proud of how that company has existed for so many years; has had the resources to jump on every new platform or technology in the Apple ecosystem; and has churned out so many high-quality products year after year. They're such an inspiration! As we push through these uncertain times, I'm sure they'll continue their leadership in this industry for many years to come.

Tons more work to do so back to coding.... more news later!

Hello 2020!

2019 was a busy year with Curio 13's release, Curiota 3.2's release, and handling macOS Catalina's tumultuous rollout with updates for Curio 12, 13, and Curiota.

We also released a subscription version of Curio available at the Mac App Store. This is in addition to our normal Curio traditional licenses sold via our website, as always. There's an extraordinarily detailed FAQ for you to peruse, if you're curious to learn more. Many thanks to the amazing RevenueCat framework and service which made integrating Apple's crazy-complex subscriptions API a piece of cake.

2020 should be busy and exciting as well. Lots of cool, new features going into Curio 14, which is still many, many months away. A ton of work was also involved updating Curio 14's internals to deal with Apple's accelerating pace of framework deprecations.

I thank everyone for supporting Zengobi with your purchases, upgrades, and subscriptions. This all began in 2002... pretty nifty that it's still going strong in 2020. πŸ€—

Curio subscriptions at the Mac App Store

At long last, our full-featured Curio application is now available at the Mac App Store!

While we still have Curio available with a traditional license from the Zengobi website, Curio from the Mac App Store will only be available as a monthly or yearly subscription. We're incredibly excited to finally offer customers both traditional licenses and subscription plans, to best suit their specific needs.

Using the Mac App Store app, Curio can be installed and used for free without a subscription in a read-only mode to view, export, and print existing projects, including the bundled Welcome to Curio project which automatically opens on first launch and provides a guided tour, complete user documentation, and sample gallery. (This is also a fast and easy way for colleagues to install Curio if you'd like to share projects with them!)

When you're ready to learn more, start a 2 week free trial by subscribing to a Professional or Standard monthly or yearly plan from within Curio, which instantly unlocks the purchased features. A Professional subscription is US$6.99/month or US$69.99/year; a Standard subscription is US$4.99/month or US$49.99/year. Localized prices available when subscribing.

If you cancel at least 24 hours before the end of the free trial period you won't be charged for using Curio, otherwise your Apple ID account will be charged, and the subscription will automatically renew at the specified rate.

All future minor updates and major upgrades are included and will be installed behind the scenes automatically and securely by macOS.

If you cancel your subscription then its auto-renewal is disabled, but you still have access to the plan features until its expiration date. After expiration, Curio will revert back into a read-only mode. You would need to re-subscribe, even if just for a brief period, to modify projects again.

Some customers may prefer traditional licenses and upgrades, others may prefer monthly or yearly subscriptions. With this new offering at the Mac App Store we allow customers to choose which product works best for them.

Many more details including all the pros and cons of subscriptions, differences in the traditional and Mac App Store products, how trials work, how to manage your subscription, and much more can be found in a very extensive Frequently Asked Questions here.

Catalina, Curio, and Curiota

We have some recent updates to announce:

Curio 13.2 was just released with loads of new enhancements and fixes, including updates to support the upcoming release of Apple's macOS Catalina (10.15). This is on top of the numerous Curio 13.1 tweaks and fixes which came out earlier this summer. With this update, Curio 13 can run on macOS High Sierra (10.13) through macOS Catalina (10.15).

Curio 12.2.3 was also rolled out with fixes to accommodate changes Apple made to Catalina's interface framework. It is also notarized, as required by Catalina, although Curio 13 is notarized and compiled with hardened runtime entitlements which is even more secure. With this update, Curio 12 can run on macOS Sierra (10.12) through macOS Catalina (10.15).

In both Curio 13 and Curio 12, the daily update check should find the new releases, although you can also choose the Curio > Check for Updates menu item to grab the update right now. Note that anyone running older versions of Curio will need to purchase a discounted Curio upgrade if they intend to upgrade to macOS Catalina.

Last, but not least, our Curiota 3.2 app was released last weekend at the Mac App Store. It also includes updates for macOS Catalina, as well as a number of enhancements and fixes based on feedback from customers. This automatic update is available via the Mac App Store app to anyone running macOS High Sierra (10.13) or greater.

Introducing Curio 13

We're thrilled to announce that Curio 13 is here!

By far the most requested feature in this release is support for macOS Mojave's Dark Mode! This required scores of changes, new graphics, and a massive number of tweaks throughout the interface. The results look fantastic!

Other big features include figure layers for more flexible layouts and arrangements; cross references between figures, idea spaces, and web locations with custom types like Agree and Evidence for more organized research; an integrated equation editor; focus mode for better concentration; additional markdown support; new album arrangements; new meta properties; major performance enhancements; plus dozens of other features and improvements.

* Note that some features are only available in certain editions of Curio. See the site for more information.

Here’s a quick video covering a bunch of the new features:

Our What's New section on the website provides a great overview of the new features or you can jump into our extraordinarily detailed release notes to learn about all the changes.

This is definitely a packed release with new productivity tools, feature enhancements, and major code updates to make Curio more robust, optimized, and ready for the future.

Note that Curio 13 requires macOS High Sierra or Mojave.

For existing customers, discounted upgrades are available to Curio 13 Professional, Standard, or Core.

We're thrilled to finally bring Curio 13 to everyone! Enjoy!

2018: a review

As I relax here during the holidays, this is a great time to write-up a quick review of 2018!

Curio's Birthday

I first started working on Curio way back in October 2002 and Curio 1.0 was released in 2004, making Curio 14 years old in 2018! It's amazing to see how far it has come! πŸŽ‰

Curio 12

We launched Curio 12 in the Spring of 2018 with an extremely popular request: markdown support! Writing in markdown, and exporting/importing markdown text, lists, mind maps, and more were extraordinarily useful additions to Curio's bag of tricks.

Curiota 3

In 2018 we also finally revealed our long-awaited Curiota 3 update! Our free, fast note-taking and file-collecting whiz kid app now supports dark mode, detachable windows, and a major user interface overhaul!


In May the GDPR European privacy initiative came into effect and Zengobi was ready with changes not just Europeans but globally so everyone has the same privacy protections.

We rolled out a new, detailed privacy policy explaining precisely how data is collected and used at Zengobi; fine-tuned out forums installation; cleaned up older, unnecessarily data collections from our sales databases; introduced a new opt-in mailing list; and much, much, more.

Basically anything that didn't need to be collected was tossed, and anything that was collected is now carefully documented.

This took a substantial amount of time but it's the right thing to do.

Thank You!

And, as I say every year, I truly appreciate all the wonderful customers that make Zengobi possible! Here's to 2019 and another year of awesome developments!

Curiota 3

Curiota 3 is here! Our free, fast, always there, easy to use macOS app for taking quick notes and collecting files with no proprietary database or file format. Now with a major user interface overhaul and detachable window support. πŸŽ‰

Read all about it here: 

Curio 12.1 and 12.2

New, free updates to Curio 12 have released over the past few weeks.

First, our Curio 12.1 release added:
  • Curio Professional and Standard text figures now support markdown inline code (monospace) syntax. Plus new support for importing markdown lists containing a mix of bulleted and numbered list elements into Curio list figures.
  • Media player shortcuts.
  • Idea space link Quick Look support.
  • More flexible trials.
  • Major performance improvements.
  • A bunch of bug fixes.

Then, Curio 12.2 was released with more goodies:
  • Curio Professional and Standard text figures now support inline markdown lists! Definitely one of our most popular requests since Curio 12's initial release.
  • More flexible alert to fix broken aliased assets or jumps.
  • A handful of bug fixes.

Again, these are free updates for existing Curio 12 customers. Curio should notice the updates automatically or you can choose the Curio > Check for Updates menu item.

For customers on older versions of Curio, discounted upgrades are available to Curio 12 Professional, Standard, or Core. Note that Curio 12 requires macOS Sierra or High Sierra.

Announcing Curio 12

We're extremely happy to announce that Curio 12 is now available!

The big feature for Curio 12 Standard and Professional customers is extensive support for markdown including on-the-fly rich text syntax rendering, plus sophisticated importing and exporting capabilities.

Here’s a quick video showing the on-the-fly markdown rendering in action:

Other new features include vastly improved PDF exporting; OmniOutliner Pro, TaskPaper, and OneNote support; searching with boolean and regular expressions; major new import/export features; enhancements to lists, mind maps, stacks, and tables; and much, much more.

Our What's New section on the website provides a great overview of the new features or you can dive into the details in our comprehensive release notes.

This is truly a massive release with amazing new features, fantastic enhancements, and a major internal code overhaul to make Curio more robust and optimized.

Note that Curio 12 requires macOS Sierra or High Sierra.

For existing customers, discounted upgrades are available to Curio 12 Professional, Standard, or Core.

We're thrilled to finally bring Curio 12 to everyone! Enjoy!

2017 review

2017 was, well, an interesting year for us here in the United States but we'll concentrate just on Zengobi. πŸ˜€

Curio 11

Curio 11 appeared on the scene and was a smashing success! πŸ‘

One of the big improvements was bringing back Professional, Standard, and Core editions. Prior to Curio 8 we had editions and customers could purchase the feature set that matched their needs. However, with Curio 8, we thought it would be smart to simplify the product line by just having a single Curio product with no editions. But this actually confused many as some wanted a cheaper, simplified product while power-users wanted much more advanced functionality and would be happy to pay for those features.

So, Curio 11 re-introduces editions with a handy feature matrix to help you determine which edition matches your productivity needs.

As a note, just 13 years prior to Curio 11's release we released Curio 1.0, which makes Curio a teenager. It's certainly come a long way!

Soon after Curio 11's release we distributed a slew of free updates including Curio 11.1, Curio 11.2, Curio 11.3, and Curio 11.4. Plus we had to make a handful of additional tweaks to work around Apple macOS High Sierra issues. πŸ™„

Curio 12?

πŸ‘·πŸΌ I've had a few inquiries about Curio 12. It's under heavy construction and still many, many months away. Really... it's a long way off.


Our move to Paddle for our  automated order processing has been a huge success. Combine that with our rock-solid Linode server, Let's Encrypt for https website and downloads, and our Discourse forums software, we're quite happy with Zengobi's back-end operations. They've never been smoother!

Thank You!

As always, our customers are the most rewarding part of this journey. Continue sending your feedback, comments, and project samples. It's wonderful to see how everyone is using Curio!

Curio 11.4

We've got another free update for Curio 11 customers! Curio 11.4 is here!

It includes several key features and improvements:
  • PRO STANDARD Prefix Calendar/Reminders synced tasks with collection name.
  • Curio now supports iThoughts file and image attachments!
  • You can now disable inherit resources in your lists or mind maps.
  • New support for variables in idea space titles.
  • Better support for older projects including read-only viewing.
  • Convert index card to list or mind map.
  • Numerous other robustness updates, tweaks, and fixes.

The complete details are in the Curio 11.4 release notes so be sure to check it out.

Happy 13th birthday Curio!

Curio 1.0 was released to the public 13 years ago today: February 17th, 2004! πŸŽ‰

Work began full-time on Curio in October of 2002. What an exciting time in the Mac's history. It's almost hard to remember Apple as a financially lean underdog with a small audience. But you could feel the energy around the new Macs; you could sense that Windows was stagnating. It was definitely a time for disruption! It was a true gamble to create a new business and product for the Mac but it was also incredibly exciting and fun!

I dug around the archives (on CD!) to see if I can find some old screenshots. Sadly I can't run Curio 1.0 anymore because I don't have a PowerPC-based Mac sitting around!

Here's a screenshot of Curio 1.0:

And here's an old movie introducing Zengobi to the world:

According to CLOC, Curio 1.0 had about 60,000 lines of source code (not including comments). In contrast, the recently released Curio 11.0 has about 230,000 lines of source code.

Curio has certainly come a long way since that first initial release. I sincerely thank you all for your continued support and emails. Keep the feedback coming... more exciting times ahead!

2016 review

What a year! 2016 has to have been one of the busiest years in Zengobi's history! Let's begin our 2016 review and a brief 2017 preview... illustrated with a few helpful emoji! πŸ˜€


Curio 10

Throughout the year there were several Curio 10 updates including a whopper Sierra fix in September (which was even regressed back to Curio 9) due to a change Apple made in Sierra's text framework which broke text editing on idea spaces (thanks, Apple). πŸ™„

Curio 10 is a huge success and I'm glad everyone has been enjoying all of its new functionality! I love getting emails from customers describing how Curio is key to their ability to truly get things done. Yay productivity! πŸš€


On August 1st, we had an out-of-the-blue surprise with Kagi's sudden shutdown. 😱 For those that don't know, Kagi has been Zengobi's primary payment handler since day 1. They've been a wonderful company to work with but, unfortunately, the terms of their closing necessitated a sudden midnight shutdown with no prior warning.

Sadly this occurred while I was on the first day of a 5-day family trip in the remote mountains. So much for a relaxing vacation.😭 Fortunately I was able to work out a fast solution with the awesome folks at Paddle so that the day I returned I was able to get an impromptu store in place to resume sales. 😘

Looking at the bright side, this was a perfect, if unexpected, time for me to massively upgrade our sales processes and back-end infrastructure. πŸ›

Backtracking a bit, in 2014 I moved Zengobi from a super old WebIntellects-hosted server to an incredibly fast, self-managed Linode server. This has been a wonderful experience. I can't say enough good things about Linode. πŸ’―

A couple of months later I ditched the old phpbb forums software for the slick, new Discourse-based forums. We love Discourse! πŸ‘

Over the months that followed more security and firewall tightening was added to the Linode server to make it more robust.

Most recently, just a few months ago, I upgraded our Linode server from 14.04 LTS to 16.04.1 LTS and enabled automatic system updating so we're always up-to-date with emergency patches. πŸ’ͺ

I also got Let's Encrypt installed and working on the machine so we could switch over to secure https for general site browsing and downloads, including Curio updates. πŸ”’

Next, I need to get our Discourse forums onto https as well. Sadly our Blogger-hosted blog can't be switched over to https, yet.


Now that we're on Paddle's payment system I was able to make a number of major, long-needed improvements. 

Previously order processing was handled with local AppleScripts and a decade-old FileMaker database. It worked but was not robust to say the least. 😳

Now everything is hosted on the server. No more FileMaker as everything is in super-speedy MySQL. New php scripts have been created to handle everything from lost license keys, to upgrade handling, to order processing via tight integration with Paddle's order processing API's. πŸ™Œ


Let me touch briefly on 2017 since a number of related events have occurred in the past few weeks.

Curio 11

Well, obviously this is the biggest news of 2017. Thirteen years after Curio 1.0's public release we have now released Curio 11. I'm so proud of Curio, in general, and of Curio 11, specifically, with all its new features and functionality. There's a related blog post here with all the details. πŸŽ‰


With Curio 11's release we also rolled out a brand new website design. Much cleaner, with a greater emphasis on what Curio's all about instead of bombarding visitors with an overwhelming number of screenshots and slideshows. πŸ˜‡

(Instead of screenshots, we guide the user within Curio itself with our fantastic new Welcome to Curio project -- a massively improved version of our old Getting Started project with integrated user documentation and sample gallery. Very slick!🌣😎)

Next Steps

Next, I'd like to create a gallery of short video tutorials perhaps even opening it up to user submissions if anyone out there would like to contribute videos showing off how they use Curio. 🎬

I'm also contemplating other user-contributed content such as styles, stencils, and templates. Still mulling this over.

Plus there are number of additions to Curio 11 coming in the next few months. Lots of awesome new functionality I can't wait to add. I'm super excited about 2017! πŸ˜ƒ
