 ## [Unreleased] (beta)
-### Fixed
-- Handle the case where an email or event cannot be retrieved from Exchange due to an `ErrorCorruptData` error. Corso will skip over the item but report it in the backup summary.
-- Emails attached within other emails are now correctly exported
-- Gracefully handle email and post attachments without name when exporting to eml
-- Use correct timezone for event start and end times in Exchange exports (helps fix issues in relative recurrence patterns)
-- Fixed an issue causing exports dealing with calendar data to have high memory usage
-
-## [v0.19.0] (beta) - 2024-02-06
 
 ### Added
 - Events can now be exported from Exchange backups as .ics files.
 - Update repo init configuration to reduce the total number of GET requests sent
   to the object store when using corso. This affects repos that have many
   backups created in them per day the most.
-- Feature Preview: Corso now supports backup, export & restore of SharePoint lists. Lists backup can be initiated using `corso backup create sharepoint --site <site-url> --data lists`.
+- Group mailbox emails can now be exported as `.eml` files.
-- Group mailbox(aka conversations) backup and export support is now officially available. Group mailbox posts can be exported as `.eml` files.
 
 ### Fixed
 - Retry transient 400 "invalidRequest" errors during onedrive & sharepoint backup.

 - In-place Exchange contacts restore will merge items in folders named "Contacts" or "contacts" into the default folder.
 - External users with access through shared links will not receive these links as they are not sent via email during restore.
-- Graph API has limited support for certain column types such as `location`, `hyperlink/picture`, and `metadata`. Restoring SharePoint list items containing these columns will result in differences compared to the original items.
-- SharePoint list item attachments are not available due to graph API limitations.
-- Group mailbox restore is not supported due to limited Graph API support for creating mailbox items.
-- Due to Graph API limitations, any group mailbox items present in subfolders other than Inbox aren't backed up.
