v1.5.0rc1

Synapse 1.5.0rc1 (2019-10-24)

This release includes a database migration step which may take a long time to complete:

• Allow devices to be marked as hidden, for use by features such as cross-signing.
  This adds a new field with a default value to the devices field in the database,
  and so the database upgrade may take a long time depending on how many devices
  are in the database. (#5759)

Features

• Improve quality of thumbnails for 1-bit/8-bit color palette images. (#2142)

• Allow uploading of cross-signing keys. (#5769)
• CAS login now provides a default display name for users if a displayname_attribute is set in the configuration file. (#6114)
• Reject all pending invites for a user during deactivation. (#6125)
• Add config option to suppress client side resource limit alerting. (#6173)
