Hello and welcome to the latest installment of the Deployment Highlightsemail.

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. Seehttps://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. Seehttps://www.mediawiki.org/wiki/MediaWiki_1.22/Roadmap

== Thursday ==

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