 ## Bug fixes
 
+### 2.7.2
+
+* Fixed bug in validation of `pattern` and `regexp` parsers where missing or empty parameters for these parsers caused panics.
+* Fixed bugs in processing delete requests with line filters:
+  * Whole chunks covered by delete requests with a line filter were incorrectly skipped.
+  * Chunks partially covered by delete requests with a line filter were not properly processed.
+    The part that was not covered by the delete request was rewritten with a line filter, while the part that was covered by the delete request was completely deleted.
+* Fixed bug in multi-tenant querying that caused HTTP 400 responses when multiple tenants where used in `X-Scope-OrgID` header like so `tenant-a|tenant-b`.
+* Upgraded Go build version and Docker container base images to 1.19.5 to mitigate [GO-2022-1144](https://pkg.go.dev/vuln/GO-2022-1144) vulnerability.
+
 ### 2.7.1 
 
 * Add single compactor http client for delete and gennumber clients. This fixes a bug caused by the accidental introduction of different HTTP clients for compactor and gennumber operations that resulted in 404s when only the gennumber middlewares were enabled:
