Hi,

Despite the increment of major version to 10, there seems to be no
outstanding backward-incompatible changes like the early days of
9.5x releases.

One notable change mentioned in the release note is the switch of
the default PDF interpreter to the brand new implementation in the
C language (appeared in 9.56) from the one written in PostScript.

If we encounter any behavior change, we are supposed to file a
bug report :-)

Ubuntu's and Fedora's distro packages will wait the upgrade
until next spring, I guess, but who knows.

        Thanks Akira
