Hi,

Sorry for the delay, there was a MassMessage bug (now fixed https://phabricator.wikimedia.org/T221570) preventing delivery of all newsletters.

The latest technical newsletter is now available at < https://meta.wikimedia.org/wiki/Special:MyLanguage/Tech/News/2019/17%3E. Below is the English version.

You can help write the next newsletter: whenever you see information about Wikimedia technology that you think should be distributed more broadly, you can add it to the next newsletter at < https://meta.wikimedia.org/wiki/Tech/News/Next%3E.

More information on how to contribute is available at < https://meta.wikimedia.org/wiki/Tech/News#contribute%3E. You can also contact me directly.

As always, feedback (on- or off-list) is appreciated and encouraged.
