Completed
The scheduled maintenance has been completed.
Scheduled
Clarification on patch version numbering: the patch released on October 16 (UAT) and October 19 (PROD), 2026 is version 2026.05.08. Two earlier patches were announced with the wrong numbers: the one announced as 2026.05.08 (late September) is actually 2026.05.05, and the one announced as 2026.05.09 (early October) is actually 2026.05.07. We are correcting the release notes on our Help and Support pages. No action is required.
This scheduled maintenance affected: Indirect Tax (ONESOURCE Determination Enterprise Cloud (AWS AMER), ONESOURCE Determination Enterprise Cloud (AWS EMEA), ONESOURCE Determination Enterprise Cloud (OCI AMER), ONESOURCE Determination Enterprise Cloud (OCI MENA)).
