Just FYI, but SeaMonkey was removed.

I upgraded about a month ago from 10.3 -> 11 > 12 on my machine, and I was so confused about different versions (i.e. the most recent stable release), when I later found out on distrowatch that ver 11.3 was just released.I very rarely get core dumps from SeaMonkey - I have it running for months at a time with a twm desktop.
 I'm using FreeBSD 11.3-STABLE, not 12 - sorry - missed that first time around.
All versions of FreeBSD use the same ports tree. As such all FreeBSD versions have the same packages/ports with the same versions. If a port gets removed it is removed for all versions.where do i check that a package such as Seamonkey is removed from ver 12 release?
Most people should use a -RELEASE version. Preferably the last major version.and I was so confused about different versions (i.e. the most recent stable release),
Yes. Keep mind this also means that support for 11.2 will end 3 months after the release of 11.3. Only the latest minor version of a major release is supported.when I later found out on distrowatch that ver 11.3 was just released.
