Blackboard Release Schedule
Each monthly release contains new features or feature enhancements, as well as maintenance items. Additional maintenance releases occur on Tuesdays and Thursdays.
Note
These dates are approximate. Your system may be updated a couple days before or after.
What does the release version number mean?
Blackboard uses a combined versioning schema for all deployments: 3900.x.-rel.abcdefg. Each digit has a specific meaning.
x – Represents the “minor” version for a given release. E.g. 3900.1 = the first continuous delivery release after the 3900 release.
-rel.abcdefg– Represents the specific build number for a release. This build number is only relevant for technical troubleshooting and internal Blackboard development systems and can generally be ignored by most customers. Blackboard Support may request this build number for validation when clients submit support cases.Note
The build number may differ between a release's stages (Test/Staging and Production). If you notice that a release's build number in your Test or Staging environment doesn't match the release's build number in your Production environment, this is normal and expected.
