4D releases 4D v12.1 Hotfix 4 [Updated]

4D v12.1 (Hotfix 4) is available

Dear Partners,

This is the fourth HotFix release for 4D v12.1!


  • As this version is an intermediate build, it has only been validated for the fixed bugs (see list below).
  • You should only use this version if you were concerned with one of these bug fixes.
  • It is recommended to backup your databases before using an intermediate version.
  • Don’t forget to read the license agreement when installing this version since it is specific to HotFix versions.

Download link is available at the end of this message (after bugs fixed list).

Sorry, 4D doesn't allow us to publish more then this - and even
for this I'm not quite sure...
Anyway. If you are a 4D Partner (Silver or Gold) go and get, it is
worth it.
Not a Partner yet? Use the our contact form and we can tell you if
it does make sense for your.

[Update: There is a little glitch in the hotfix and it cooled down. After a warming up a new one will be released]
