Draft Tomcat 9 LTS announcement
All,
Draft Tomcat 9 LTS announcement follows. Feedback welcome. The plan is
to send this - or something along these lines - to users and announce by
the end of next week.
*** DRAFT *** DRAFT *** DRAFT *** DRAFT *** DRAFT ***
Subject: Tomcat 9 long term support plan
The Tomcat team has consistently stated that long term support (LTS)
will be provided for Tomcat 9 as it is the last Tomcat version that
supports Java EE. The details of that LTS have been evolving over time.
As we approach the point where we'd normally be announcing
end-of-support (EOS) for Tomcat 9, the Tomcat team is pleased to
announce the following LTS plan for Tomcat 9.
Tomcat 9 support will continue until 31 December 2030 - the same date as
EOS for many Java 8 distributions.
Tomcat 9.0.x support will continue until 31 March 2027.
Shortly before 9.0.x support ends, releases from a new 9.1.x branch will
be made available. Releases from the 9.1.x branch will continue until 31
December 2030.
The differences between 9.0.x and 9.1.x will be minimal and users can
start making the necessary transition now. Those changes are:
- the APR/native connectors for HTTP, HTTPS and AJP will not be
available
- Tomcat Native 1.3.x will not be supported (see the separate EOS
announcement for Tomcat Native 1.3.x)
Users of the APR/native AJP connector are strongly encouraged to migrate
to the NIO AJP connector and discontinue using Tomcat Native.
Users of the APR/native HTTP connector are strongly encouraged to
migrate to the NIO HTTP connector and discontinue using Tomcat Native.
Users of the APR/native HTTPS connector are strongly encouraged to
migrate to either the the HTTPS NIO+JSSE connector or the HTTPS
NIO+OpenSSL connector.
Those migrating to the HTTP NIO+OpenSSL connector should then upgrade
Tomcat Native to 2.0.x.
For users that are not using Tomcat Native or are using Tomcat Native
2.0.x, the transition from 9.0.x to 9.1.x will be no different to a
normal Tomcat point release upgrade.
Rather than continuing on 9.1.x, Tomcat 9 users are strongly encouraged
to consider upgrading to a more recent Tomcat version making use of
tools like the Tomcat Migration Tool for Jakarta EE.

Maybe state explicitly "last Tomcat version that supports Java EE.
Higher Tomcat versions switched to Jakarta EE."
I assume for some people responsible for TC 9 use, it is still not
clear, that there are two incompatible worlds of EE and what the switch
means. So only stating that we no longer support "Java EE" might sound
for them like "no longer support EE".

I think we need to have "EOL" or "end of life" in the title, to get more
attention.

You do so below, but I think we should say 2.x isn't being dropped up here.

There has been no further feedback so I intend to send this out
tomorrow. I'll also send out the more standard EOS notice for Tomcat
Native 1.3.x

Posted by Mark Thomas <ma...@apache.org>.
Thanks for the feedback. Updated draft follows. The plan is still to
send this put next week, along with a basic end of support notice for
Tomcat Native 1.3.x that states support for that will end 31 March 2027.

Subject: Tomcat 9.0.x End of Support and Tomcat 9 long term support plan
The Tomcat team has consistently stated that long term support (LTS)
will be provided for Tomcat 9 as it is the last Tomcat version that
supports Java EE. Tomcat 10 onwards switched to Jakarta EE. The details
of that LTS have been evolving over time. As we approach the point where
we'd normally be announcing end-of-support (EOS) for Tomcat 9, the
Tomcat team is pleased to announce the following LTS plan for Tomcat 9.
- Tomcat 9 support will continue until 31 December 2030 - the same
date as EOS for many Java 8 distributions.
- Tomcat 9.0.x support will continue until 31 March 2027.
- Shortly before 9.0.x support ends, releases from a new 9.1.x branch
will be made available. Releases from the 9.1.x branch will continue
until 31 December 2030.
The differences between 9.0.x and 9.1.x will be minimal and users can
start making the necessary transition now. Those changes are:
- the APR/native connectors for HTTP, HTTPS and AJP will not be
available
- Support for Tomcat Native 2.0.x will continue but Tomcat Native 1.3.x
will not be supported (see the separate EOS announcement for Tomcat
Native 1.3.x)
Users of the APR/native AJP connector are strongly encouraged to migrate
to the NIO AJP connector and discontinue using Tomcat Native.
Users of the APR/native HTTP connector are strongly encouraged to
migrate to the NIO HTTP connector and discontinue using Tomcat Native.
Users of the APR/native HTTPS connector are strongly encouraged to
migrate to either the the HTTPS NIO+JSSE connector or the HTTPS
NIO+OpenSSL connector.
Those migrating to the HTTP NIO+OpenSSL connector should then upgrade
Tomcat Native to 2.0.x.
For users that are not using Tomcat Native or are using Tomcat Native
2.0.x, the transition from 9.0.x to 9.1.x will be no different to a
normal Tomcat point release upgrade.
Rather than continuing on 9.1.x, Tomcat 9 users are strongly encouraged
to consider upgrading to a more recent Tomcat version making use of
tools like the Tomcat Migration Tool for Jakarta EE.
