Legoktm claimed T196132: wikidiff2 binaries are not distributable due to PHP / GPL license incompatibilities.
Yep; PHP is now GPL-compatible so it's totally fine to distribute built binaries under the GPL. I'll put up a patch updating the repo shortly.

The upstream PHP License, which was historically based on the BSD license with a "twist", has finally been untwisted and superseded into the BSD-3-Clause license.

thiemowmde closed T202304: Mobile diff does not show the cutting points between two diffs as Resolved.
Looks like there are ⋮ in the visual diffs now at exactly the points where we missed them before.
Jdlrobson edited projects for T202304: Mobile diff does not show the cutting points between two diffs, added: MediaWiki-Page-diffs; removed Platform Team Workboards (Clinic Duty Team), MobileFrontend (Tracking).
Is this ticket still relevant? Untagging MobileFrontend as MobileFrontend no longer has any diff code.
Jdlrobson closed T281056: Diffs hard to read in Special:MobileDiff (broken up into per word) as whitespace is considered a delimiter as Resolved.
The mobile site now uses the same code as the desktop site. Please see T358293 for more information. For any new or related bugs please file them under MediaWiki-Page-diffs

tstarling added a comment to T340738: wikidiff installed +x.
This is not specific to wikidiff2. The problem is somewhere in the PHP build system.
I don't really think it's necessary. Pages can have multiple languages on them. The content language is not necessarily correct. We're detecting whether the page contains Thai characters and running Thai word breaking only if Thai was detected. Profiling indicates that this is not a significant performance problem.

tstarling closed T339915: Show wikidiff2 version in Special:Version's softwareInformation as Resolved.
This was done in ecdd1a34bef120d6ddd6ff3e4e37faecc1bfb922, citing T339915.
I split off a formatter hierarchy in 6d62f503fd7063a8d3b57f50e85da5b7780b5a6b. I hope that solves the problem sufficiently.
There was a bug in argument parsing which could have caused this, and it was fixed in c77f72ee4d6f95d25d14f89c2a9f670f2bf438e5. Please reopen this task if the crash is reproducible with wikdiff2 1.14.1.
wikidiff2 configuration settings are now available as $wgWikidiff2Options in MediaWiki.
