@@ -9,23 +9,20 @@
 ### Bugs Fixed
 
 ### Other Changes
+* Python 2.7 and 3.6 are no longer supported. Please use Python version 3.7 or later.
 
 ## 12.2.0 (2021-11-10)
-
 **Warning** This release involves a bug fix that may change the behaviour for some users. Partition and Row keys that contain a single quote character (`'`) will now be automatically escaped for upsert, update and delete entity operations. Partition and Row keys that were already escaped, or contained duplicate single quote char (`''`) will now be treated as unescaped values.
 
 
 ### Bugs Fixed
-
 * Resolved bug where strings couldn't be used instead of enum value for entity Update Mode (#20247).
 * Resolved bug where single quote characters in Partition and Row keys were not escaped correctly (#20301).
 
 ### Features Added
-
 * Added support for async iterators in `aio.TableClient.submit_transaction (#21083, thank you yashbhutoria).
 
 ### Other Changes
-
 * Bumped dependency on `msrest` to `>=0.6.21`
