Tiki 21.0 will be released in February 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 February March 2025 as per the Tiki lifecycle policy

About getting source code

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

See: H5P

1.19. Links, from absolute to relative

Add preference to convert tiki instance absolute URLs with relative URLs in content: URL conversion from absolute to relative

1.20. LDAP / Active Directory support

1.21. Map / Location / OpenStreetMap

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:

1.21.1. Clustered Features (Map)

 Open Layer Terminology
"feature" is what OpenLayers calls a "thing on a map"

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

1.22. MathJax

1.23. MediaWiki importer

Add support to import information in the MediaWiki format 0.6 to 0.10
MediaWiki Importer

1.24. Menu revamp

Remove the CSS menu (suckerfish/superfish) menu type, and enhance Bootstrap menus with the SmartMenus system, which offers most suckerfish features and also permits "Mega Menus" (enhancement as an admin option) - http://sourceforge.net/p/tikiwiki/code/66963 .

1.25. Minification

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

See Minify CSS

1.26. Modules

New or enhanced.

1.26.1. Site logo module

Admins can now easily change the site logo by hovering over it, clicking the icon that appears and uploading a new logo directly to file gallery.

To perform a search by choosing from multiple search engines.

1.26.3. Module to switch admin language

1.26.4. Module to enable quick admin bar

Top Admin Bar works on the top position and gives a mini control panel to Tiki Admins.

1.26.5. Module permissions

New module. This module lists the permissions for current object. It help site admins know which group has which permission on the current object, and how (ex.: object permissions vs category permissions vs global permissions)

See Module permissions

1.27. Multilingual

1.28. Newsletter

1.29. OCR Indexing

A new feature to index content after Optical Character Recognition (OCR) was added via https://packagist.org/packages/thiagoalessio/tesseract_ocr and it even led to some enhancements upstream

See OCR Indexing

1.30. OAuth2

Add OAuth2 support via https://oauth2.thephpleague.com/
See: OAuth

Using https://github.com/ApoorvSaxena/lozad.js

1.32. PDF

1.32.1. mPDF updated

1.32.2. PDF.js

For PDF viewing, we will start using code directly from Mozilla's PDF.js, and installable via Packages -> PDF.js viewer

1.33. Permissions

1.33.1. Module to help site admin to know who has which permission on each object

1.33.2. Mini-revamp

This section needs cleanup.
  • 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.

1.33.3. List ordering

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.

1.34. Perspectives - sticky

1.35. Profiles

http://sourceforge.net/p/tikiwiki/code/66243 (backported to 18.x)

1.36. Progressive Web App

1.37. Roles

1.40. Share


1.41. Slideshow revamped

1.42. Spam protection improvements

  • 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.

  • antibot captcha


1.43. Stats

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.

1.44. Templated Groups

1.45. Themes

Converted from Bootstrap 3 to 4

1.45.1. Theme Customizer

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

1.45.4. FiveAlive theme - revamp

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.

1.45.5. Removal of outdated themes

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.

1.46. Tiki Objects: maintainers and freshness

  • Upgraded to Converse 4.x which now uses Bootstrap 4 like Tiki, and thus, it will be easier to provide a consistent user experience. See also PluginXMPP

2. General upgrade notes

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.

3. Dependencies

  • 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/
  • mPDF 7.1

4. Cleanups

http://sourceforge.net/p/tikiwiki/code/65966 (also backported to 18.x)

5. Regressions

5.1. Removals

Exact search with ElasticSearch (added in Tiki 18.3) was removed.

5.1.1. Jison

This experiment never got to viability

5.1.2. jQuery.s5

jQuery.s5 is no longer updated, so it was replaced by the Reveal.js library (which is pretty awesome!)

5.1.3. Mods

As of Tiki 19, Mods are completely obsolete. All mods-related code has been removed from Tiki. Details: https://tiki.org/forumthread67983-About-Tiki-Packages-in-Tiki-18-0-LTS-and-why-I-support-this-project-And-mods-tiki-org-can-now-be-scheduled-for-retirement

5.1.4. Report system (experimental)

  • This never worked, and was duplicating another feature. One of Tiki's strengths is that we converge all energies on a common functionality. This experiment had some interesting aspects but it was not viable. All the details here: https://tiki.org/forumthread67333

5.1.5. WebODF and ViewerJS

As of Tiki19, ViewerJS, which includes WebODF, will no longer be supported because no significant work has been done since 2015

PDF viewing will now be done with PDF.js viewer instead
