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.
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 .
1.16. 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
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 Analytics and PiwikMatomo 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.

1.29. Themes
Converted from Bootstrap 3 to 4
1.29.1. Theme Customizer
"Style Guide Tool" renamed to "Theme Customizer" and converted to Bootstrap 4
The Tikipedia theme was added to the package following user requests. It was evaluated that there is no license incompatibility issue.
1.29.4. 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.
1.29.5. 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.
Display "Error" (warning) alert on wiki pages with duplicate alias wiki links (e.g. (alias(FooBar))). When the same alias is used in 2 or more wiki pages, links using that alias do not work properly.
Enhanced. See Button. You can now display an icon without label (text).
1.35.2. Plugin Diagram
New. See PluginDiagram. PluginDiagram integrates mxGraph (An open source JavaScript diagramming component, started in 2005, that works on all major browsers, including touch devices), to provide a service like draw.io but that you can install on your own server.
1.35.3. Plugin Gantt Chart
New. It allows to produce and easily edit Gantt chart diagrams based on data in a tracker.
New. Enables page layout configuration such as removing the page footer, having full-width page section backgrounds, etc. Useful for making a splash page that looks radically different from the other site pages.
New. A carousel/rotator/slideshow that supports images and other content. Basically a replacement for other similar plugins that are no longer supported or are less advanced.
Enhanced. Some usability improvements have been made to facilitate new users to join the edition of a page currently being editted by another user which started the collaborative session.
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. Upgrade
Specific upgrade notes regarding using this Tiki version compared to using the previous one Tiki18.
Note Tiki 19.x 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/
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
In the Look and Feel admin options, two layout templates ("Wider side columns" and "Fixed top navbar 1") were removed because they were very similar to other layout templates.
5.2. Known Bugs
Mail notifications when wiki pages are edited are mostly broken in Tiki 19.0. (fixed for 19.1)
Bootstrap Tour broken, needs library update. See item6677
