Hey folks,

This is the weekly update for the Revision Scoring project for the week of
May 2nd through May 8th.

New developments:

• Solved some issues that block a major performance improvement for score requests using multiple models[2]
• Improved the performance of feature extraction for features that use mwparserfromhell[3,4]
• We applied regex performance optimizations to badwords and informal word detection for many languages[9]

Maintenance and robustness:

• Solved a regression in ScoredRevisions that caused most revisions in RecentChanges to not be scored[1]
• Set ORES load balancer to rebalance on 500 responses from a web node[5]
• Enabled CORS for error responses from ORES -- this makes it easier to report errors from a gadget on a wiki[6]
• Sade the staging instance of Wikilabels[7] look a lot more like the production instance[8]
