    Version 1.9.1

    • prevent multiple syncs to be run at the same time for the same account and authority (hopefully fixes duplicate entries – if you have duplicate entries, please uninstall DAVdroid and try with 1.9.1 again)
    • better handling of contact group method change (now resets contacts when method is changed; doesn't change method automatically)
    • events: support ACCESS_CONFIDENTIAL (read more; we don't know a calendar app which supports that yet, but we will contact calendar app developers)
    • improve resource detection
    • minor bug fixes and optimizations

  • developer

    Version 1.9.2

  • developer

    Version 1.9.3

    • improved custom certificate support
    • raise API level to 19 (Android 4.4); Objects required by ical4j
    • various minor improvements and bug fixes (including fixed crashes on Android 4.x)

    If you need DAVdroid for an older Android version, we recommend to use the F-Droid Archive. The latest formally compatible versions may not work – in this case, you can go back until you find a working version. If ever possible, updating your Android version using a Custom ROM is much better than using old app versions (just think about TLS ciphers which are not supported by old Android versions yet, WiFi/BT vulnerabilities etc.).

  • developer

      • use uid and sync_version field for tasks
      • now requires OpenTasks
    • bug/crash fix and minor optimizations

  • developer

    Version 1.9.10

    Please note that if you upgrade from v <1.9 to 1.9.4 ≤ v < 1.9.10 directly, the upgrade will still fail (causing all collections to be shown as read-only without possibility to change that). In this case, you have to uninstall DAVdroid and install it again (or to delete all DAVdroid accounts, clear app storage and add the accounts again).

    Upgrading from any version, including <1.9, to 1.9.10 should work without problems.
