I think that this is now the replacement for the old mozilla.dev.tech.js-engine mailing list ([https://groups.google.com/g/mozilla.dev.tech.js-engine/c/hkqD0xh3nRs])
Over the last year we have done the massive task of upgrading our embedding to ESR78 (from 1.8.5). Now that we’ve done that I want to make sure that we keep up to date as I don’t want to have to go through that again!
Looking at the Firefox release calendar it looks like the next ESR release will be ESR91 in July and I would like to target this as the next release to move to.
Looking at treeherder it looks like the current release is 87.
Can anybody recommend if I should try to upgrade to the current release and then upgrade again to ESR91 later in the year or would I be better just waiting for ESR91 and upgrading in one step?
Are there any big changes that I should be aware of (either in terms of API changes or toolsets required for compiling etc) that have already happened or that are planned between now and ESR91?
If anybody has any thoughts I would be very grateful.
If I’m better asking this in chat.mozilla.org instead then please let me know.
