I decided it might be a good idea to make beta 3 of the current development version of Pale Moon public as 20.3 beta 3.

The reason being that it seems to be stable, but some major changes have been made that could do with some testing "in the field" before they are finalized in the next release version.

The updates of note in this beta 3:
Change of the compiler to VS2012 Update 3 - with better binary code generation (could potentially show in benchmarks)
Change of the networking to have more aggressive failovers in case of congestion, which should further reduce any wait times if there is a networking issue.
Memory management has changed to (hopefully) reduce the memory footprint of Pale Moon in cases where lots of extensively navigated tabs are used.

This is a beta - not intended for the general public at large.
It will not update or retain an up-to-date blocklist. You will have to manually move to the release version once it is out.
