==== Product Infrastructure ====
* Updates:
** Pagelib
*** CSS now minimized. Deployed yesterday
*** Experimenting with pagelib to improve mobile-html pageload
https://phabricator.wikimedia.org/T231201
** Mobile-html
*** Fixed srcset in media-list endpoint
*** WIP: updating footer style
** Maps
*** Investigated OSM DB bug, but results inconclusive
** Machine vision middleware
*** Could be (optimistically) code-complete by EOW for DBA, Performance
pre-deployment reviews
*** Planning JS frontend integration
** Data Engineering
*** Specified identifiers for event platform clients
*** Specified sampling functions for event platform clients

==== Structured Data ====
* Updates:
** working on getting structured data in campaigns ready for WLM

==== Parsing ====
* Updates:
** Parsoid/PHP testing:
*** Parser tests almost 100% green now (barring some insignificant
key-value ordering differences in JSON blobs which we need to normalize to
reduce this false positives).
*** We have got our first runs of Parsoid/PHP round trip tests running
scandium. We still have some crashers to fix and more bugs to fix from that
initial test run.
** Performance-wise, after Tim's initial work tweaking some things in
Parsoid, here is a rough performance update for test runs on scandium. We
need real perf. benchmarking to get a more robust sense of where we are.
*** Parsoid/PHP w2html:
**** On large pages (like en:Barack_Obama), 1.5x slower than Parsoid/JS.
But, most of that seems to be GC issues (both PHP7.2 and Parsoid/PHP). See
https://phabricator.wikimedia.org/T230861 for details
**** On medium and smaller pages, as fast as or upto 2x faster than
Parsoid/JS in some cases which is a pretty good result.
*** Parsoid/PHP html2wt (impacts VE and CX):
**** On large DOMs (like en:Barack_Obama), >2x slower than Parsoid/JS. But,
on slightly smaller DOMs (like en:Berlin), < 10% slower. So, we seem to be
getting non-linear slowdown as the pages get larger.
**** Needs additional testing on medium and smaller sized pages.
**** Note that in production usage, we will be using a more efficient
version of html -> wt. But, this slowdown is still a reliable indicator of
where we need to focus our performance work.
** Other Parsoid/PHP updates:
*** Working with core platform team on RESTBase - Parsoid/PHP integration
testing.
