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.
