Originally at the end of September 2023...
Most people should probably upgrade to MW 1.39 as the next LTS, supported until November 2025.
However, as 1.39 was late (released in November 2022), 1.35 should be supported till the end of November 2023, as per the "year overlap" commitment.
This was announced in {T340867}.
Therefore, the EOL of 1.35 will co-incide with the release of MW 1.35.13 in December 2023.
Previous: {T330174}
```
As per the MediaWiki version lifecycle[1], I would like to announce the formal end of life (EOL) of MediaWiki 1.35 as of today, Thursday December 21, 2023.
1.35.13 is expected to be the last release for this branch.
This means that MediaWiki 1.35 will no longer receive maintenance or security backports. It is therefore strongly discouraged that you continue to use it.
It is recommended to upgrade either to MediaWiki 1.39 (LTS), which will be supported until November 2025, 1.40, which will be supported until June 2024, or to 1.41 (due to be released today, Thursday December 21, 2023) which will be supported until December 2024.
Thanks!
