Hi Leopold,

copying pkg-kde-talk that would be more appropriate for this kind of 
discussion than the individual maintainers.

TLDR; unlikely.

Yes, that’s very good to know, indeed.

There are several things that make it unlikely:
- there need not be ABI break in poppler
- the poppler maintainers must be OK with targeting this version for 
bullseye, the first thing would be to contact them and see their plans 
then revert to us if/when they actually upload this version
- the changes for Okular would also need to not break the ABI for 
libokular5core${abi} or this would require a transition…
- …and be integrated into the 20.12.x series, or be light enough that we 
would feel comfortable backporting the upstream changes to the 20.12.x 
series in Debian.

I’ve not discussed this this with the team so that’s my own view but I 
plan to upload 20.12.x updates as they come as long as they’re 
compatible with the freeze policy and can migrate to testing. The 21.04 
series is out for bullseye.


Happy hacking !
