Starting on April 9th we'll migrate the servers running the Mediawiki application servers to a new release of the ICU Unicode library ($icu) (from version 52 to 57). This unblocks some future work on upgrading the servers to a new OS release and will also allow the use of improved internationalisation in the future (as wikis will then be able to use features introduced by the new ICU release such as new collation definitions, and allows us to use a more recent version of Unicode in MediaWiki).
