[SCIP] Question: Upgrade from 8.0.4 to 9.x.x

[Stefan Vigerske]

Hi,

SCIP 9.0.0 was a major release, which comes with changes to the API and 
parameters that are not backward compatible. These are documented in the 
release notes ("Interface changes" in 
https://www.scipopt.org/doc-9.2.1/html/RN9.php#RN900), so if you studied 
them and found that they are not relevant for you, then transition may 
be smooth. There have been new features and, of course, SCIP will behave 
differently (more often better than worse) on many instances.

Minor and bugfix releases (8.1.0, 9.x.y after 9.0.0) should be 
backward-compatible and bring only small new features, but many bugfixes.

Stefan
