Unless I'm missing something, the [[https://gitlab.wikimedia.org/repos/test-platform/catalyst/patchdemo/-/blob/bdf4f6fea0e03e1b836f84ff87abc383e26912ec/repository-lists/tarball.yaml|'tarball' Patch demo preset]] -- which I believe is intended to include extensions & skins that are [[https://www.mediawiki.org/wiki/Bundled_extensions_and_skins|bundled along with the MediaWiki release]] -- hasn't been updated [[https://gitlab.wikimedia.org/repos/test-platform/catalyst/patchdemo/-/commit/bb9c74d0e5bab0fd2871dde5414173402722aeb7#ddb9e6ec2fe38aac02cfddcd0413e1c704d392ec|since it was originally created in October 2020]] (except [[https://gitlab.wikimedia.org/repos/test-platform/catalyst/patchdemo/-/commit/ac6e614029e4f99a4882f111768ee72be13a9e22|2 weeks ago]] by @jnuche to remove the archived #mediawiki-extensions-localisationupdate extension).
There have been a number of changes to the list of bundled skins/extensions since then, so the Patch demo preset should be updated to reflect the changes to it that've been made.
As far as I'm aware, the authoritative/canonical list for bundled skins/extensions is contained within https://gitlab.wikimedia.org/repos/releng/release/-/blob/main/make-release/settings.yaml ([[https://gitlab.wikimedia.org/repos/releng/release/-/blob/e358bf04db00e434a0192d7ac147221e2b494300/make-release/settings.yaml#L7-47|permalink]]).

-- no new extensions/skins were bundled from `MW1.41 ≤ ver ≤ MW1.43`; T333405 started life as a task for MW1.41 but eventually morphed into being a task for MW1.44 instead.
- **MediaWiki 1.44** - {T333405}

#### Future planning
- [ ] Create a follow-up task for the next set of changes that will need to be made in the future; set it to stalled, and add it as a parent task of {T392080} so we're notified the next time we need to update the preset.
