End of year deployment freeze 2025

Hi all!

MediaWiki Train deployment will pause for the final two weeks of 2025: 22
December and 29 December.

Backport windows will pause between Mon, 22nd of December 2025 and
Thursday, 02 January 2026.

End-of-year holidays and a team offsite mean there are seven deployment
trains left in 2025 for MediaWiki:

- 25 Oct – 1.45.0-wmf.25 (This week)

- 03 Nov – 1.46.0-wmf.1

- 10 Nov – 1.46.0-wmf.2

- 17 Nov – 1.46.0-wmf.3

- 24 Nov – 1.46.0-wmf.4

- 01 Dec – 1.46.0-wmf.5

- 08 Dec – 1.46.0-wmf.6 No Train, backports normal (Release Engineering at
Offsite)

- 15 Dec – 1.46.0-wmf.7

- 22 Dec – 1.46.0-wmf.8 No Deploys (Holiday: Tue–Fri)

- 29 Dec – 1.46.0-wmf.9 No Deploys (Holiday: Mon–Wed)

All this information is on the yearly deployment calendar[0].

We freeze deployments every year for the end-of-December holidays and

the busy fundraising season[1][2][3][4][5][6][7].

Thanks!
