I just updated some wikis to 1.35.5 and also installed the current skins
and extensions that I use.
On .../Special:Version, the version of MediaWiki itself is correctly
shown as "1.35.5", but the versions of the skins and extensions have
remained at the versions before (or even some updates before). For
example: I have installed "Metrolook-REL1_35-7671f0e", but
7.0 alpha 2 (74d7661) 18:04, 4. Sep. 2021
which I had installed before. Another identical wiki shows
7.0 alpha 2 (abd1ca1) 14:40, 18 April 2021
I see the same for e.g. PluggableAuth: Installed is
"PluggableAuth-REL1_35-efff551", but I see
5.7 (e5976c0) 03:13, 4. Sep. 2021
5.7 (2a465ae) 00:07, 11 July 2020
Are the versions somewhere stored in the database and not updated properly?
