STAC Patch 2.90.1 is available

ATTENTION:

As mentioned in our Release Review meeting today 4/22/26, there was a bug reported in STAC 2 causing E-files to not send successfully. 

Please upgrade using the Patch 2.90.1, if you have not upgraded your Production environment yet. 

If you have already upgraded Production with version 2.90.0, please upgrade again or contact CIP so we can apply the fix manually to avoid issues E-filing!

Users that have STAC 3:

Please upgrade STAC 2 to version 2.90.1 (patch release) before proceeding with the upgrade of STAC 3 to RC-5.

No patch or configuration changes are required for STAC 3; therefore, the previously provided link for the RC-5 upgrade remains valid and should be used.

Thank you
