qdb> "MediaWiki requires the PSR-3 logging library to be present" - cannot i just turn that logging off?
No answer anywhere:
$ grep -B 1 PSR RELEASE-NOTES-1.25
- The debug logging internals have been overhauled, and are now using the PSR-3 interfaces.
- Add breaking change and new installation requirement to release notes
- Add requirement to https://www.mediawiki.org/wiki/Manual:Installation_guide#Upgrade_guide
- Evaluate what needs to be included in the release tarball
- Depending on amount of work needed by sysadmins, add a note and link on [[MediaWiki 1.25]] and mediawiki-l
