 - Remove support for MongoDB 3.6 which has reached its End-of-Life date and PostgreSQL 10 (Manuel Trezza) [#7315](https://github.com/parse-community/parse-server/pull/7315)
 - Remove support for Node 10 which has reached its End-of-Life date (Manuel Trezza) [#7314](https://github.com/parse-community/parse-server/pull/7314)
 - Remove S3 Files Adapter from Parse Server, instead install separately as `@parse/s3-files-adapter` (Manuel Trezza) [#7324](https://github.com/parse-community/parse-server/pull/7324)
+- Remove Session field `restricted`; the field was a code artifact from a feature that never existed in Open Source Parse Server; if you have been using this field for custom purposes, consider that for new Parse Server installations the field does not exist anymore in the schema, and for existing installations the field default value `false` will not be set anymore when creating a new session (Manuel Trezza) [#7543](https://github.com/parse-community/parse-server/pull/7543)
 
 ### Notable Changes
 - Added Parse Server Security Check to report weak security settings (Manuel Trezza, dblythy) [#7247](https://github.com/parse-community/parse-server/issues/7247)
