XMP, incremental versions record keeping, 2.0 features sound interesting
to me.
My thoughts are mostly about existing issues... these are the ones that
people have spoken out about.

Dear colleagues,
with 3.0 being released and 4.0 being started I'd like to start
discussing what the major plans are for 4.0. And maybe in a way that
the release can be made faster than what we had for 3.0. (maybe size it
in a way that we can do the dev stuff by spring 2024 and then release
in summer 2024 followed by a 4.1 release to add to that instead of
doing a big bang like 3.0)
Shall we share some ideas via the mailing list or start a page on our
website (I think ml is easier to do). We can still document the major
initiatives as soon as we have agreed in a blog post.
Here are my current thoughts (some of which might also be backported to
3.0) in no particular order
- appareance stream handlers for interactive form widgets (similar to
what we have for annotations) also allowing one to add their own
handler
- replacement or at least new base for XMPBox (current thought is to
have a new base parser and add if possible XMPBox current end user api
on top - might be able to reuse xmlgraphics XMP lib). Would allow to
better deal with XMPs which are not standard and make it easier to add
to existing XMPs low level.
- then we had the discussion about an event handler/listener similar to
what fop provides so one can listen to corrections/repairs done under
the hood (I know that we can only lay the ground for that as this is a
major undertaking given all the places where we correct things)
- enhance the parsing to keep the information about incremental
versions (better debugging, trace of changes done ...)
- review and add some more PDF 2.0 capabilities
- better text formatting/language support (maybe by including fop parts
or looking into using HarfBuzz)
- I'd also like to discuss reaching out to fop to look at integrating
some of their font handling into fontbox
...
That list is already long and I think would be too much given above
idea of release planning.
With regards to versioning I'd like to propose that we have 2.0 as LTS
and 4.x being the next LTS.
