Announce upcoming formal EOL of REL1_31
Closed, ResolvedPublic
Actions

Description

REL1_31 is stated to become EOL in June 2021; even if this is the end of the month of June, that is still only ~2.5 months away (of writing).

It would be eligible to be in the next security release (1.31.15), but then that would be it.

While we've mentioned it in some previous announcements, we should probaly do a couple of followup announcements, reminding and encouraging people to upgrade in time. Maybe one at the start of May and one at the start of June make sense....

Along with mentioning it in the REL1_36 release announcements too...

Did we ever do a stand-alone upcoming EOL announcement/reminder? Closest I can find for REL1_27 is https://lists.wikimedia.org/pipermail/mediawiki-announce/2019-June/000231.html (final EOL announcement) plus mentions in the final release (https://lists.wikimedia.org/pipermail/mediawiki-announce/2019-June/000230.html except it was broken so https://lists.wikimedia.org/pipermail/mediawiki-announce/2019-June/000232.html).

Here's a quick draft:

Subject: MediaWiki 1.31 will soon be End-of-Life

This is a reminder that MediaWiki 1.31 will soon reach its End-of-Life date and users should consider upgrading in the near future.

June 2021 is the scheduled End-Of-Life date for MediaWiki 1.31 (the old LTS version). This means that the expected MediaWiki 1.31.15 will be the last security release for that version, barring any unforeseen issues.

We encourage users of MediaWiki 1.31 to upgrade to MediaWiki 1.35 (LTS version), released in September 2020, ahead of its final release. MediaWiki 1.35 will be supported until September 2023, and has a number of feature improvements alongside the extended security support window. See <https://www.mediawiki.org/wiki/Version_lifecycle> for more information.

More usually it's been tacked onto another email that was being sent at the right time - https://lists.wikimedia.org/pipermail/mediawiki-announce/2020-September/000259.html

And then followed up with the "it's over" one - https://lists.wikimedia.org/pipermail/mediawiki-announce/2020-November/000266.html

That means that we'll announce the final release as such with no prior notice. Sending something now would give people three months' notice to get their stuff sorted and start migrating, which might be nicer?

Yeah. It was more an answer to your "Did we ever do a stand-alone upcoming EOL announcement/reminder?"

April is nearly over. May starts soon... So even end of June is basically only two months!

So this is about sending an MediaWiki 1.31 soon to be End of Life heads-up email out to a bunch of lists, like "Please upgrade to the 1.35 LTS version within the next weeks to stay safe and secure" stuff?

Yes.

I propose:

Subject: MediaWiki 1.31 will be End-of-Life next month

Hello all,

I wanted to send a heads-up to various places that MediaWiki 1.31, the legacy LTS release, will be End-of-Life as of next month, June 2021.[0] There will be a final release to follow-on from the current latest version 1.31.14 coming out soon, but it may have slipped people's mind that this deadline is approaching so swiftly.

System administrators still using 1.31 are encouraged to start their migration to the current LTS release, 1.35. MediaWiki 1.35, released in September 2020, will be supported until September 2023. If you don't require LTS support, you will be able to upgrade to 1.36 which will be supported till May 2022 once it is released, probably later this week.

As always, please be mindful of the upgrade instructions, especially including making a back-up of your database, and testing extension compatibility.

Thanks!
