Tiki 21.0 was released in March 2020.

It requires PHP 7.2, vs PHP 7.1 for Tiki20, and at least MySQL version 5.5.3, which provides support for utf8mb4 encoding.

It is a Long Term Support (LTS) version and will be supported until March 2025 as per the Tiki lifecycle policy

Please note: SVN updates (for all versions of Tiki) will stop in January 2023 when Tiki18 reaches end of life, so you should get your updates from Git

Add warning message in admin control panel when Tiki detects vendor folder issues: http://sourceforge.net/p/tikiwiki/code/66408
Top quick admin bar and sticky floating apply buttons for admin forms. Detail at Tiki19 Admin Enhancements

This is the most far reaching upgrade in Tiki19: Moved from Bootstrap 3 to 4.
See https://themes.tiki.org/Bootstrap-3-to-4-transition

As Tiki transitions from Bootstrap 3 to 4, support for Internet Explorer 8 and 9 is being dropped. Internet Explorer 10 also stops being fully supported officially, but it should mostly work.

Moved from old no-longer supported fork fullcalendar-resourceviews to latest and greatest official FullCalendar, and Scheduler (GPL) available via Packages -> https://sourceforge.net/p/tikiwiki/code/66298
Also using Bootstrap 4!

From Tiki20.1 and up It is possible to use Open Layers version 3 as well as version 2 (default). Version 3 offers many improvements that will help using Map and Location related features. Enhancements will/can be implemented and it started with the following:

From Tiki20.1 and up The open Layer 3 (see above) "Clusters Features" add the capability to display group of Features / Objects (points, markers, zone, etc) based on distance from a determined feature (see terminology)
Exemple: https://openlayers.org/en/latest/examples/cluster.html

Make the filenames of minified CSS files be based on the contents of all the files, not just the filenames, so that when anything changes within a file, i.e. after an upgrade or bug fix, browsers will automatically get the new version of the code. Since this uses a server-side cache which is not validated, client-side cache will only be forced after the Tiki server's cache is cleared. This had already been done for JavaScript in Tiki 18.x

• Module permissions

• parent/child functionality and tests for: files/file galleries, posts/blogs, threads/forums, events/calendars, articles/topics. It also adds the necessary tests for this functionality.
• tracker item permission links, so users can set up permissions on individual tracker items
• extended permission page to show if the permissions you view are global, category based, parent object based or direct. New thing here is parent object permissions - so if you view a child objects permissions and are actually looking at parent's object, it says so and offers a link to go and edit the parent object's permissions (i.e. tracker ones) directly.

Now, almost all of this work will be useless unless we offer Tiki users a way to manage permissions on the child level. I think that's the purpose of this task, right? I mean, up to now, there was no way of setting tracker item individual permissions, blog posts individual permissions, article individual permissions, calendar items individual permissions and so on. There is no such UI. We also don't have ability to set up individual file permissions but all file-related permissions work on the file gallery. This commit makes it possible to use parent-level permissions for all these entities but we still don't have UI to set those permissions. Furthermore, there are numerous places in Tiki where permissions are enforced and they all work on the parent-level - i.e. checking if a file could be downloaded actually checks if you have download permission on the file gallery file resides in. I plan to change this the following way:

• anywhere a child permission is needed, it is checked first and then the parent one is used (e.g. download a file, view a blog post, edit an article, etc.)
• anywhere a parent permission is needed, it is still checked on the parent level (e.g. upload a file in a gallery, add a blog post, etc.)
• add Permission links to all Wrench icon/settings menu items for all the child entries - i.e. allow users to edit individual blog post, file, article, forum thread or calendar event permissions.

At tiki-objectpermissions.php it is now possible to order the Permissions by modifying the way you want the tiki-objectpermissions_order.yml file.

You can edit db/config/tiki-objectpermissions_order.yml and move the permission in the order you prefer.
This is reserved for power users for now but it may soon help to improve Tiki UX by "better" organising the permissions or an option for several set distributed with the release.

• Google ReCaptcha V2 has been upgraded to Google ReCaptcha 3

Tiki in its goal to be an ocean of several useful and secure features for the user, we have chosen to give you the opportunity to choose between different versions of spam security features.
Which is why you can currently choose in the settings to activate the Google ReCaptcha 2 or 3 version.

• How will reCaptcha V3 stop spam?

The previous ReCaptcha (v2) worked because it tracked the user movement (scrolling, clicking) while the user solved the captcha (clicked on "I'm not a robot"). v3 does the same, but there is just no button to click on, google just "watches" the client and determines wether there is a human controlling the mouse on the other side.

• What if a hacker spams the URLs on my site with an external tool without using the interface I provide?

Google generates a token for the client when he passes the checks which you have to validate on the serverside. If someone doesn't pass the captcha (a robot), he doesnt have the token.

• How to activate Google ReCaptcha V3 in Tiki?

In control panel, press the "Security" feature, then the "Spam Protection" tab,
Then go to https://www.google.com/recaptcha/intro/v3.html
Create a site, add your domain, and then select version 3 of google ReCaptcha, and validate.
You will get two keys that are scrolled in Tiki respectively and then copy-paste and validate and here you are with version 3.

Google Analytics and Piwik Matomo Analytics: Added a way to include or exclude groups.

Use case: when a Tiki instance has a combined use case of a public website and a restricted Intranet, it's nice to have Piwik Matomo and / or Google Analytics for anonymous visitors to see most popular pages, time on site, etc. But for logged in users, it's not so interesting and it skews the stats.

• Templated Groups

Converted from Bootstrap 3 to 4

"Style Guide Tool" renamed to "Theme Customizer" and converted to Bootstrap 4

Experimental: https://sourceforge.net/p/tikiwiki/code/67603

The code of the FiveAliveHS ("Happy Scroll") that was added earlier replaced the FiveAlive theme code, so in effect the FiveAlive theme was revamped. The two-color site header background style is now implemented as child theme options. Alternative child themes for each color have solid-color (gradient) backgrounds for easier handling of color contrast between the site logo/title color and background.

Several themes were removed from the package because of dated or quirky appearance or close similarity to other themes. These themes may be provided as aftermarket installs on request.

• Starting with Wiki Pages, Tiki objects now can have maintainers, an update frequency and a freshness, i.e., how long ago it has been updated. Then, when an object becomes too old relative to its update frequency, Tiki will send emails to the maintainers reminding about the need to update it (console.php objects:notify-maintainers)

Also, see the standard information about Upgrades in Tiki.

Since version 19.x, Tiki uses utf8mb4 storage and there is an upgrade script built in which will do this automatically for you when the database it updated. However if, for some reason, your database (as opposed ot the tables within it) is set to use utf8mb4 already, many of the old upgrade patches will fail. To avoid this make sure the database is set to use utf8 only.

• Most dependencies were upgraded to latest version: Composer. Some notable ones:
• Smarty was upgraded. We had been stuck on v3.1.21 for a long time due to template inheritance issues, but the current release is v3.1.32 and we need this for php7.1+ support: done in https://sourceforge.net/p/tikiwiki/code/66842/
