20251129.1 (2025-11-29)
-----------------------

- featurette: link to instantaneously reload the version information for PHP, the database server and its product name, attention: there is a delay of 10 seconds after the latest reload

- change: the default font size of the main content of the forum pages is now 1rem
- change: removed many font size and line height definitions which are obsolete with the change to the default font size of 1rem
- change: put (more or less) all occurences of radio buttons and checkboxes into lists
- change: use more modern techniques for making the left column of settings tables lookong different than the other column(s) and table rows of other tables striped, this makes the use of classes .a, .b, .c and .d in each row or column obsolete
- change: optimise the code to generate and set the sorting icons in the heading cells of the user data listing tables
- change: use the narrow non breaking space for the (R) marker for registered users
- change: remove the ability to sort the users data listing table (not the one on the admin panel!) by e-mail-addresses because the addresses are invisible for the visitor
- fix: use classic formatting of the ISO-timestamps with the PHP function date, with INTL-date-formatter the ISO date will falsely be localised
- fix: remove outdated JS-code to include images which are already gone
- fix: make the function links in user data, categories, smilies, pages and bookmark tables appearing in one line and not breaking into a second line

20251021.1 (2025-10-21)

-----------------------

- fix: correct the BB-code [media] and [flash] rendering, it didn't work if the forum setting autolink was enabled
- fix: rendering of old entries with BB-code [flash], regular expression didn't match links to Youtube

20250921.1 (2025-09-21)
-----------------------

- feature: BB-code for video and audio media (supports native HTML elements audio and video and YouTube content in iframes, old media which BB-code flash is supported again (read only))
- feature: almost all pixel images of the default theme are now replaced with natively scalable SVG images
- feature: add a message bar on all pages for the case, that the forum is disabled; for logged in administrators the forum is accessible and looks enabled so they may overlook the actual status of the forum
- feature: replace the JS-based popover code for images which are displayed with their thumbnails in postings with the native HTML popover which are still generated with JavaScript, without working JavaScript the thumbnails still link to the image itself
- feature: add the infrastructure to separate the lists for files to upload and files to delete in the upgrade process; this will work only with future versions, not for the current upgrade!

20250422.1 (2025-04-22)
-----------------------

- fix: when introducing the new feature of adding entries for existing but unmanaged uploads we changed a column name but forgot to change in in the upload processing script, corrected the column name
- fix: when introducing the new feature of adding entries for existing but unmanaged uploads we changed the column definition for the uploaders ID to store only NULL or IDs of existing users, this did not take into account entries from users that have since been deleted, check for such entries and set the uploaders ID to NULL before changing the column definition
- fix: when adding the attribute UNSIGNED to several index columns we forgot to define AUTO_INCREMENT for column mlf2_tags.id, this caused hiding of completely new tags behind an invalid index
- fix: remove a superfluous comma in a postings metadata in the template themes/default/subtemplates/entry.inc.tpl
