 * Deployments in 2013
 * Deployments in 2014

Monday, Feb 2, 2015, around 1pm PST: ✅

 * Set X-Forwarded-Proto when proxying https. This fixes timeouts for ruwikinews which is strict about accepting only https connections.
 * Some performance tweaks to attribute expander to eliminate useless work and useless memory allocation
 * : Fixes to resource module loading URI in the section of Parsoid HTML
 * Fixes to tokenizer to ensure that strings starting with '-' are parsed for directives like language variant markup

Friday, Jan 30, 2015 around 2:35 pm PST: ✅
The Jan 15th deploy where Parsoid started using sitematrix info for configuring wikis was missing special handling for some wikis (commonswiki being one of them). This caused timeouts which in turn repeatedly exercised an existing memory leak. This, in turn, caused a slow buildup of leaked memory on the cluster and a higher than normal cpu load. This special Friday deploy fixed the config issues.

Specifically, the following two patches were deployed:
 * Some special wikis should use the default proxy
 * Strip TLS from sitematrix url if we're using the default proxy

Wednesday, Jan 28, 2015 around 1pm PST: ✅

 * : Correctly handle templates that generate part-attribute and part-content of a DOM node.
 * : Preserve blank template parameters
 * : Cleanup of behavior switch production
 * Updates to wikitext serializer to simplify and enable more robust wikitext escaping
 * ,, : Magic link fixes (wt2html and html2wt nowiki handling)

Thursday, Jan 15, 2015 around 1pm PST: ✅

 * ,, : Default WMF wikis served by Parsoid fetched from sitematrix API call
 * : Positional params with = in extlink are serialized as named parameters

On Jan 14th 1:20 pm PST, we reverted Parsoid to older deployed version after dirty diffs were seen during post-deploy testing. It turned out that the dirty diffs weren't related to the Parsoid deploy, but now that those issues have been fixed, we'll revisit the Parsoid deployment on Thursday.

Monday, Jan 12, 2015 around 1pm PST: ✅

 * Include location of titles in timeout logs
 * Tweaks to Parsoid's cite port to generate identical ref ids as native cite implementation

Wednesday, Jan 7, 2015 around 1pm PST: ✅

 * : Improved handling of extremely large lists -- fixes the load issues seen in production on Jan 3rd
 * Removed hardcoded HTTP 500 response for urwiki:نام_مقامات_اے (deployed on Jan 3rd to prevent this page from overloading the cluster)
 * : Fix edge case tokenizing table lines

Monday, Jan 5, 2015 around 2pm PST: ✅
Wikitext -> HTML HTML -> Wikitext Other (API, logging, etc)
 * : data-parsoid stripped from template content
 * : Context-aware parsing of definition list colon
 * : Parse extension parameters as plain text
 * : Stray is parsed to meta
 * Marginal improvement parsing templates in definition lists
 * , : Several improvements and fixes to nowiki protection for quotes
 * Other improvements and bug fixes to nowiki protection in headings, lists, tables.
 * : Insert an extra newline after new content and existing headings
 * Add logging for html2wt API endpoints
 * Fix robots.txt route
 * Send SIGKILL to kill a timed out worker
 * : API v2 parsing and serialization routes
