[Wikitech-l] Deployment Highlights - Week of May 20th, 2013

[Greg Grossmeier]

Hello and welcome to the latest installment of the Deployment Highlights
email.

The full calendar for next week lives at:
https://wikitech.wikimedia.org/wiki/Deployments#Week_of_May_20th

For the week of May 6th we have the following interesting deployments:

== All Week ==

* Due to a security update to the Linux kernel, we will be upgrading and
  rebooting ALL machines throughout the week. This may affect your
  experience with some services, but it should be minimal.


== Monday ==

* VisualEditor will be deploy a new extension, TemplateData, to all
  Wikipedias (<https://bugzilla.wikimedia.org/show_bug.cgi?id=44444>) in
  addition to a VisualEditor configuration change on mediawiki.org
  (<https://bugzilla.wikimedia.org/show_bug.cgi?id=48430>).

* English Wikipedia will be updated to MediaWiki version 1.22wmf4, in
  addition to a WikiData client update on English Wikipedia. See
  <https://www.mediawiki.org/wiki/MediaWiki_1.22/Roadmap>

* An update to HTCP purging will be rolled out by the WMF Operations
  team which might create momentary issues with some thumbnails. Please
  report any issues you experience.


== Wednesday ==

* The rest of the Wikipedias will be updated to MediaWiki 1.22wmf4, thus
  completing the roll out of that version. The next version, 1.22wmf5,
  will start on Monday May 27th. See
  <https://www.mediawiki.org/wiki/MediaWiki_1.22/Roadmap>


== Thursday ==

* The Editor Engagement team (E2) will rollout bugfixes to Notifications
  (Echo). See <http://etherpad.wikimedia.org/echo-release>.


Best,

Greg
