AIMMS PRO Cloud Updates
PRO Cloud build release notes for the AIMMS Cloud Platform pipeline, starting from the point where AIMMS PRO Cloud and on-premise builds diverged. For releases before that split, see the AIMMS PRO Release Notes Archive.
PRO 26.6
AIMMS PRO 26.6.2 Release
On August 13, 2026 we released AIMMS PRO 26.6.2(Cloud build: 26.6.2.2)
Improvements
Faster app startup when using authentication functions: Calls to pro::authentication:: functions during app startup could take up to 15 seconds, causing a noticeable delay before the app became usable. This has been fixed by introducing a more efficient method for listing group, user, and environment relations. Authentication calls are now significantly faster, resulting in quicker startup times.
Resolved Issues
Apps that display past runs or sessions could time out when loading that list, especially for heavily used apps. This is now fixed — session lists load significantly faster.
Fixed an issue where WinUI apps published with AIMMS 4.98 or lower cannot launch on Cloud.
AIMMS PRO 26.6.1 Release
On July 23, 2026 we released AIMMS PRO 26.6.1(Cloud build: 26.6.1.1)
Improvements
New toolset support: Added support for a new compiler toolset, in preparation for upcoming AIMMS and AutoLib releases that will use it.
Frozen binaries updated for the old toolset: The frozen binaries used for the old toolset have been updated.
