After discussion within the WMF Product and Engineering teams along with the Wikimedia Deutschland developers (mainly for Wikidata) I have decided to rearrange the MediaWiki "train" deployment schedule.

The changes are relatively minor (simply day of week and time of day) but I want everyone to be aware of the changes. The changes will take effect starting next week (the week of October 27th).

For a quick reference of what the new schedule is, please see: https://wikitech.wikimedia.org/wiki/Deployments/One_week

The salient changes are: * I've moved the Thursday deployment to Wednesday at the same time ** This is the day when a new version goes to testwikis and mediawiki.org AND the previous branch goes to all Wikipedia projects. ** This will give developers and product managers more time to assess and fix any issues found after their code hits production for the first time.

* I've also moved the Tuesday deployment to 5am Pacific (from 11am Pacific) ** This is the day when we deploy the new version to non-Wikipedia projects (ie: Commons, Wiktionary, etc). ** This will allow the Wikidata team to more easily (and with a better work/life balance) respond to issues after their code hits their primary wikis.

Let me know if you have any questions,

Greg
