The "Connector Docs" page has two tables on the left hand side.
The first table is the monthly parser releases. (7.14.1, 7.14.2, 7.14.3, etc.)
If you scroll down, you'll see the second table which has the quarterly framework releases. (7.14.0, 7.13.0, 7.12.0 etc)
You will find the official 7.14 release note documentation under the quarterly framework section.
Hope this helps.
