+Bugfixes
+* The `table_info` global attribute will now contain the table's file name. ([#970][pr-970]{:target="_blank"})
+  * Example: `table_info = "Name: CMIP7_atmos.json; Creation Date: ...`.
+* The default `history` global attribute text was updated to remove the redundant "CF standards" wording. ([#969][pr-969]{:target="_blank"})
+  * CMOR now writes `history` entries in the form `CMOR rewrote data to be consistent with <Conventions> and <mip_era> data requirements.`
+* Time-interval validation now runs for `time1` axes even when bounds are not supplied in `cmor_axis`. ([#972][pr-972]{:target="_blank"})
+
+Changes
+* Climatology time axes are excluded from interval checking in `cmor_write`. ([#972][pr-972]{:target="_blank"})
+
+CI / Tests
+* CMIP7 Python tests now use the latest CV file from `cmip7-cmor-tables` instead of the stale test CV. ([#973][pr-973]{:target="_blank"})
+  * Removed outdated CMIP7 JSON files from `TestTables/`.
+  * Test cleanup now removes temporary input and CV files created during runs.
