As part of routine systems maintenance, I’ve updated the following components:
ElasticSearch to version 7.8 (which adds improved stemming for some languages, but required significant changes to the search code)
Node to the 12.x LTS series
Ubuntu on the server from the 16.04 LTS series to 18.04 LTS
There should be no significant user-facing impact of these changes, but if you notice anything no longer working as it did, please don’t hesitate to file an issue.
