I suspect the US holiday weekend means some folks are still catching up
on email. I have tried to write this down on the wiki:
https://cwiki.apache.org/confluence/display/TOMCAT/Jakarta+EE+Release+Numbering

I plan to allow a week or so for dev@ comments and refining of the plan
before starting a discussion on users@

I'll also seek feedback from the Spring folks as $work as that
represents a reasonable slice of our Tomcat's user base.

Good idea, I like it too. That Jakarta EE 9 is the ultimate transition
release so it would be fitting if it had the most transitional Tomcat
branch.

Are we done already ? That was fast :)

Hmm. Tricky.

How about something like this?

10.0.0.M1 Jakarta EE 9
10.0.0.M2 Jakarta EE 9
10.0.0 Jakarta EE 9 stable
10.0.1.M1 Jakarta EE 10 dev

10.0.0.1 Jakarta EE 9 some urgent bug fix
10.0.1.M6 Jakarta EE 10 dev
10.0.1.M7 Jakarta EE 10 dev
10.0.1.M8 Jakarta EE 10 dev
10.0.1Jakarta EE 10 stable
...
10.0.nJakarta EE 10 stable / Tomcat 10 stable / 10.0.0 is EOL

Well, it sounds pretty good to me but the numbers are off and it's going to
be very very confusing. It pretty much has to be:
Tomcat X supporting Jakarta EE X
Tomcat X-1 supporting Jakarta EE X-1
Tomcat X-2 supporting Jakarta EE X-2
And Tomcat 9.X supporting Java EE 8 with the same Tomcat API as Tomcat X [I
understand the rationale for this to be able to achieve very long term
support - and I expect the API changes will likely be rather small anyway
-, for example 8.5 and 9.0 have diverged too much to keep 8.5 more stable,
while if we had a 8.6 "trunk" to simply replace it eventually we could have
kept in strict sync with 9.0]

The only problem then (but it's a big one) is to accommodate the Tomcat
"10" supporting Jakarta EE 9 somewhere. Maybe 9.9 can be used for that but
it will still pollute a bit the 9.x message, it could be labelled as a
"Jakarta preview" or something maybe. Jakarta EE 9 is a useless release
anyway, nobody will use it and that Tomcat could almost be EOLed
immediately after a Jakarta EE 10 release.
