Add the new schedule option "If last job was Missed" to allow a backup job to run as soon as the Comet client is reconnected when there are missed jobs
You can now select "If last job was Missed" from the schedule dialog.
When a device re-connects to the server and detects that it has recently missed a backup, it will immediately start a new backup job.
This replaces the previous option "When PC starts, if last job was missed". The "If last job was Missed" option bypasses any issues with fast startup, hibernation or sudden power off interrupting a backup schedule.
Deprecation: Comet Server no longer supports Windows Vista or Windows Server 2008. Note that the Comet Backup desktop app continues to support Windows Vista and Windows Server 2008; this only affects Comet Server. Windows Server 2008 R2 is still supported for both Comet Server and the Comet Backup desktop app.
Deprecation: Removed support for U2F for two-factor authentication for admin users due to the impending removal of U2F from browsers (see !https://groups.google.com/a/chromium.org/g/blink-dev/c/xHC3AtU_65A). Existing U2F 2FA will be automatically migrated to use WebAuthn when the Comet Server instance is upgraded; this requires no action on an admin's part, and the same U2F devices can continue to be used.
Added support for WebAuthn for two-factor authentication for admin users, including support for Windows Hello Face / Fingerprint / PIN, Android Safetynet / Fingerprint and other Hardware Security Keys
