What we don't promise is full forwards compatibility, which is what you are asking for. Correct. Within the stable branch I'd always assumed forward compatibility was the case and haven't been bitten by this since my days of FreeBSD 3.0. But even if this is no longer the case (or was never a goal), I'm still confused by versioning packages like this: http://pkg.FreeBSD.org/${ABI}/ which is clearly not correct. There is just no way for me to discover which package is compatible with which OS version. Anyhow, thanks for listening. This is putting a dent in my adoption of the accelerated EOL of minor releases. At the very least I need to remember to keep poudriere on the x.0 release even after it is EOL, until every one of my servers has been upgraded (which is rarely before the new accelerated EOL for machines that don't face the internet).
