 Maintainer Notes:

 - This must be done with extreme caution - and with a great amount of care
 and pre-testing - as this is a foundational port. (With 340+ dependents,
 as of 2023-07-16.)

 - Upstream's release notes mention that there are some breaking changes,
 including removal of deprecated APIs. This almost guarantees that some
 ports - particularly those that are older, and/or no longer maintained by
 upstream - will break.

 Given all of the above, this will take plenty of time before we can
 update. And ultimately, it's possible that we may have to create a new
 segregated port - say, `libjpeg-turbo-3` - to maintain backward
 compatibility for those ports that don't work with 3.x.
