Ok, thanks for explaining. I am new to Free Pascal.

What is the best way to check which version of TFieldType is in use? Is the 
compiler patch number changed when changes like this occur? Is there a more 
reliable method than looking at the compiler version?

As Sven says, the fixes branch is a mix of development-at-arms-length
and a rigid stable branch(as in bugfix only). In practice it means that
compiler changes are usually real bugfixes (the rigid part), but runtime
and library changes and fixes are merged when they are considered stable
(the development-at-arms-length part) and don't depend on new language
features.

The criterium is mostly that the merges must be possible without too
much hand interference (which could possibly introduce bugs due to the
merging), in the past there have been exceptions to that for specially
major Mysql versions.

New mysql major versions are also one of the main reasons why also
features are added, otherwise you could now only use 6 year old
mysql/mariadb versions (not that it is much better with the current
fixes release frequency)

A few attempts were made at also providing wholly rigid stable branches
for e.g. corporate use, but those initiatives to my best knowledge
petered out.

The reasons are rooted in release frequency, but also spreading out
library fixes more to avoid the dreaded "don't use .0 versions" syndrome
by mitigating the amount of changes in library code that hasn't seen
wide usage yet in new major (.0) releases.
