#310 Add paq8px because it's the highest performance PAQ
PAQ8PX gives better compression than PAQ8O, but it is missing from PeaZip. I like using PeaZip to test via trial-and-error to see which format gives the best compression. Having the best formats available is one of the greatest things about PeaZip, so I hope this one gets added. Also, ZPAQ was updated to version 6.50 a few days ago, so it would be nice to get that updated in PeaZip too.
Is this something that would be straightforward to do, for a person with no experience with FreePascal and Lazarus?

Thank you for reporting, I'll test the newest paq and zpaq releases.
PeaZip is fully modular, you can simply replace any backend with other versions / variants until the same syntax is used - i.e. replace PAQ version in PeaZip\res\paq\ folder - but, if the syntax changes code has to be changed accordingly.
A workaround, if syntax changes, may be adjusting syntax manually in "Console" tab (in this way PeaZip acts just as a file manager to pass groups of files/folders to the command), but this may be adviced just for experimenting and would not be handy for routine operation.
I'm closing this request as ZPAQ supeseded PAQ project, and recent compression test shown it provides better compression with performances improved by nearly one order of magnitude, see in example "Final recommendation" in PeaZip compression benchmark:
