The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

## [Unreleased] (beta)

### 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.

### Fixed
- Retry transient 400 "invalidRequest" errors during onedrive & sharepoint backup.
- Backup attachments associated with group mailbox items.
- Groups and Teams backups no longer fail when a resource has no display name.
- Contacts in-place restore failed if the restore destination was empty.
- Link shares with external users are now backed up and restored as expected

### Changed
- When running `backup details` on an empty backup returns a more helpful error message.
- Backup List additionally shows the data category for each backup.

### Known issues
- Backing up a group mailbox item may fail if it has a very large number of attachments (500+).
- Event description for exchange exports might look slightly different for certain events.
- Exchange in-place restore may restore items in well-known folders to different folders if the user has well-known folder names change based on locale and has updated the locale since the backup was created.
- 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.

## [v0.18.0] (beta) - 2024-01-02

### Fixed
- Handle the case where an email cannot be retrieved from Exchange due to an `ErrorInvalidRecipients` error. In
this case, Corso will skip over the item but report this in the backup summary.
- Fix `ErrorItemNotFound` errors when restoring emails with multiple attachments.
- Avoid Graph SDK `Requests must contain extension changes exclusively.` errors by removing server-populated field from restored event items.
- Improve Group mailbox(conversations) backup performance by only downloading new items or items with modified content.
- Handle cases where Exchange backup stored invalid JSON blobs if there were special characters in the user content. These would result in errors during restore.

### Known issues
- Restoring OneDrive, SharePoint, or Teams & Groups items shared with external users while the tenant or site is configured to not allow sharing with external users will not restore permissions.

### Added
- Contacts can now be exported from Exchange backups as .vcf files

## [v0.17.0] (beta) - 2023-12-11

### Changed
- Memory optimizations for large scale OneDrive and Sharepoint backups.

### Fixed
- Resolved a possible deadlock when backing up Teams Channel Messages.
- Fixed an attachment download failure(ErrorTooManyObjectsOpened) during exchange backup.

## [v0.16.0] (beta) - 2023-11-28

### Added
- Export support for emails in exchange backups as `.eml` files.
- More colorful and informational cli display.

### Changed
- The file extension in Teams messages exports has switched to json to match the content type.
- SDK consumption of the /services/m365 package has shifted from independent functions to a client-based api.
- SDK consumers can now configure the /services/m365 graph api client configuration when constructing a new m365 client.
- Dynamic api rate limiting allows small-scale Exchange backups to complete more quickly.
- Kopia's local config files now uses unique filenames that match Corso configurations.  This can protect concurrent Corso operations from mistakenly clobbering storage configs during runtime.

### Fixed
- Handle OneDrive folders being deleted and recreated midway through a backup.
- Automatically re-run a full delta query on incremental if the prior backup is found to have malformed prior-state information.
- Retry drive item permission downloads during long-running backups after the jwt token expires and refreshes.
- Retry item downloads during connection timeouts.

## [v0.15.0] (beta) - 2023-10-31

- Improve check to skip OneNote files that cannot be downloaded.
- Fix Groups backup for non Team groups

### Changed
- Groups restore now expects the site whose backup we should restore

### Added
- Enables local or network-attached storage for Corso repositories.
- Reduce backup runtime for OneDrive and SharePoint incremental backups that have no file changes.
- Increase Exchange backup performance by lazily fetching data only for items whose content changed.
- Added `--backups` flag to delete multiple backups in `corso backup delete` command.
- Backup now includes all sites that belongs to a team, not just the root site.

### Fixed
- Teams Channels that cannot support delta tokens (those without messages) fall back to non-delta enumeration and no longer fail a backup.

### Known issues
- Restoring the data into a different Group from the one it was backed up from is not currently supported

### Other
- Groups and Teams service support is still in feature preview

## [v0.13.0] (beta) - 2023-09-18

### Added
- Groups and Teams service support available as a feature preview!  Channel messages and Files are now available for backup and restore in the CLI: `corso backup create groups --group '*'`
  - The cli commands for "groups" and "teams" can be used interchangeably, and will operate on the same backup data.
  - New permissions are required to backup Channel messages.  See the [Corso Documentation](https://corsobackup.io/docs/setup/m365-access/#configure-required-permissions) for complete details.

### Added
- Added `export` command to export data from OneDrive and SharePoint backups as individual files or as a single zip file.

### Added
- Sharepoint library (document files) support: backup, list, details, and restore.
- OneDrive item downloads that return 404 during backup (normally due to external deletion while Corso processes) are now skipped instead of quietly dropped.  These items will appear in the skipped list alongside other skipped cases such as malware detection.
- Listing a single backup by id will also list the skipped and failed items that occurred during the backup.  These can be filtered out with the flags `--failed-items hide`, `--skipped-items hide`, and `--recovered-errors hide`.
- Enable incremental backups for OneDrive if permissions aren't being backed up.
