26R1 Maintenance Releases
Last Updated: April 29, 2025
A "maintenance release" is a release that contains fixes for issues that are affecting customers in production environments. We communicate 24 hours prior to the release that we will be applying a maintenance release and that there will be a short service disruption. This list only covers fixes to General Release versions.
The list of fixed issues is not finalized until just before the release occurs. When we identify issues to fix in a maintenance release, we attempt to get them into the earliest release possible. Sometimes, we target a specific release but are not able to deliver a fix early enough for full testing. In situations like this, we postpone the fix for a later release and strike out the description in this list.
We number maintenance releases by appending the number of the maintenance release to the General Release number. Veeva Clinical Data uses odd-numbered releases, while Vault uses even-numbered releases. The most recent General Release was 26R1, so our maintenance releases for this version are 26R1.0.3, 26R1.0.5, and so on.
