It’s very rare to perform an update without any issues.
This is my second update of Lazarus.
Windows XP service pack 3
Updated from Lazarus 0.9.30.4 to Lazarus 1.0
Recompiled Lazarus 1.0 to add the service pk
Recompiled two large projects no problems.
This really is an excellent product.
Gold medals for the Lazarus team.
