## Changes Since 3.0.17

### Build changes

- Fixed: iCal GEO property is text in new libical versions

- Fixed: docs now build correctly with python3 and Sphinx 3.4

### Bug fixes

- Fixed Issue #4002: cyradm: allow LIST command even when support_referrals is false

- Fixed Issue #4216: httpd killed by SIGSEGV for calendar request (thanks Дилян Палаузов)

### Other changes

- Fixed Issue #4380: `backend_version()` now properly parses the remote server's version string, and can recognise when it is newer than the local server. This means XFER to a newer backend no longer requires a local software update to recognise the new version number first.
