Version 0.19.2

  • Improve the performance of SingleFileStorage. issue #818
  • Properly document some caveats of the Google Contacts storage.
  • Fix crash when using auth certs. issue #1033
  • The filesystem storage can be specified with type = "filesystem/icalendar" or type = "filesystem/vcard". This has not functional impact, and is merely for forward compatibility with the Rust implementation of vdirsyncer.
  • Python 3.10 and 3.11 are officially supported.
  • Instructions for integrating with Google CalDav/CardDav have changed. Applications now need to be registered as “Desktop applications”. Using “Web application” no longer works due to changes on Google’s side. issue #1078

Version 0.19.1

  • Fixed crash when operating on Google Contacts. issue #994
  • The HTTP_PROXY and HTTPS_PROXY are now respected. issue #1031
  • Instructions for integrating with Google CalDav/CardDav have changed. Applications now need to be registered as “Web Application”. issue #975
  • Various documentation updates.

Version 0.19.0

  • Add “shell” password fetch strategy to pass command string to a shell.
  • Add “description” and “order” as metadata. These fetch the CalDAV: calendar-description, CardDAV:addressbook-description and apple-ns:calendar-order properties respectively.
  • Add a new showconfig status. This prints some configuration values as JSON. This is intended to be used by external tools and helpers that interact with vdirsyncer, and considered experimental.
  • Update TLS-related tests that were failing due to weak MDs. issue #903
  • pytest-httpserver and trustme are now required for tests.
  • pytest-localserver is no longer required for tests.
  • Multithreaded support has been dropped. The "--max-workers has been removed.
  • A new asyncio backend is now used. So far, this shows substantial speed improvements in discovery and metasync, but little change in sync. This will likely continue improving over time. issue #906
  • The google storage types no longer require requests-oauthlib, but require python-aiohttp-oauthlib instead.
  • Vdirsyncer no longer includes experimental support for EteSync. The existing integration had not been supported for a long time and no longer worked. Support for external storages may be added if anyone is interested in maintaining an EteSync plugin. EteSync users should consider using etesync-dav.
  • The plist for macOS has been dropped. It was broken and homebrew generates their own based on package metadata. macOS users are encouraged to use that as a reference.

Changes to SSL configuration

Support for md5 and sha1 certificate fingerprints has been dropped. If you’re validating certificate fingerprints, use sha256 instead.

When using a custom verify_fingerprint, CA validation is always disabled.

If verify_fingerprint is unset, CA verification is always active. Disabling both features is insecure and no longer supported.

The verify parameter no longer takes boolean values, it is now optional and only takes a string to a custom CA for verification.

The verify and verify_fingerprint will likely be merged into a single parameter in future.

Version 0.18.0

Note: Version 0.17 has some alpha releases but ultimately was never finalised. 0.18 actually continues where 0.16 left off.

  • Support for Python 3.5 and 3.6 has been dropped. This release mostly focuses on keeping vdirsyncer compatible with newer environments.
  • click 8 and click-threading 0.5.0 are now required.
  • For those using pipsi, we now recommend using pipx, it’s successor.
  • Python 3.9 is now supported.
  • Our Debian/Ubuntu build scripts have been updated. New versions should be pushed to those repositories soon.

Version 0.16.8

released 09 June 2020

  • Support Python 3.7 and 3.8.

This release is functionally identical to 0.16.7. It’s been tested with recent Python versions, and has been marked as supporting them. It will also be the final release supporting Python 3.5 and 3.6.

Version 0.16.7

released on 19 July 2018

  • Fixes for Python 3.7

Version 0.16.6

released on 13 June 2018

  • Packagers: Documentation building no longer needs a working installation of vdirsyncer.

Version 0.16.5

released on 13 June 2018

  • Packagers: click-log 0.3 is required.
  • All output will now happen on stderr (because of the upgrade of click-log).

Version 0.16.4

released on 05 February 2018

  • Fix tests for new Hypothesis version. (Literally no other change included)

Version 0.16.3

released on 03 October 2017

  • First version with custom Debian and Ubuntu packages. See issue #663.
  • Remove invalid ASCII control characters from server responses. See issue #626.
  • packagers: Python 3.3 is no longer supported. See pull request #674.

Version 0.16.2

released on 24 August 2017

  • Fix crash when using daterange or item_type filters in google_calendar, see issue #657.
  • Packagers: Fixes for new version 0.2.0 of click-log. The version requirements for the dependency click-log changed.

Version 0.16.1

released on 8 August 2017

  • Make DAV discovery more RFC-conformant, see pull request #585.
  • Vdirsyncer is now tested against Xandikos, see pull request #601.
  • Subfolders with a leading dot are now ignored during discover for filesystem storage. This makes it easier to combine it with version control.
  • Statuses are now stored in a sqlite database. Old data is automatically migrated. Users with really large datasets should encounter performance improvements. This means that sqlite3 is now a dependency of vdirsyncer.
  • Vdirsyncer is now licensed under the 3-clause BSD license, see issue #610.
  • Vdirsyncer now includes experimental support for EteSync, see pull request #614.
  • Vdirsyncer now uses more filesystem metadata for determining whether an item changed. You will notice a possibly heavy CPU/IO spike on the first sync after upgrading.

  • Fix a bug that would completely break collection discovery.

Version 0.13.0

released on 29 September 2016

  • Python 2 is no longer supported at all. See issue #219.
  • Config sections are now checked for duplicate names. This also means that you cannot have a storage section [storage foo] and a pair [pair foo] in your config, they have to have different names. This is done such that console output is always unambiguous. See issue #459.
  • Custom commands can now be used for conflict resolution during sync. See issue #127.
  • http now completely ignores UIDs. This avoids a lot of unnecessary down- and uploads.

Version 0.12.1

released on 20 August 2016

Version 0.12

released on 19 August 2016

Version 0.11.3

  • Add a .plist example for Mac OS X.
  • Usage under Python 2 now requires a special config parameter to be set.
  • Various deprecated configuration parameters do no longer have specialized errormessages. The generic error message for unknown parameters is shown.
    • Vdirsyncer no longer warns that the passwordeval parameter has been renamed to password_command.
    • The keyring fetching strategy has been dropped some versions ago, but the specialized error message has been dropped.
    • An old status format from version 0.4 is no longer supported. If you’re experiencing problems, just delete your status folder.

Version 0.10.0

released on 23 April 2016

Version 0.8.0

released on 27 January 2016

  • Keyring support has been removed, which means that password.fetch = ["keyring", "", "myuser"] doesn’t work anymore.

    For existing setups: Use password.fetch = ["command", "keyring", "get", "", "myuser"] instead, which is more generic. See the documentation for details.

  • Now emitting a warning when running under Python 2. See issue #219.

released on 05 November 2015

  • Un-break testsuite.

Version 0.7.1

released on 05 November 2015

  • Packagers: The setuptools extras keyring and remotestorage have been added. They’re basically optional dependencies. See for more details.
  • Highly experimental remoteStorage support has been added. It may be completely overhauled or even removed in any version.
  • Removed mentions of old password_command in documentation.

Version 0.7.0

released on 27 October 2015

  • Packagers: New dependencies are click_threading, click_log and click>=5.0.
  • password_command is gone. Keyring support got completely overhauled. See Storing passwords.

Version 0.6.0

released on 06 August 2015

  • password_command invocations with non-zero exit code are now fatal (and will abort synchronization) instead of just producing a warning.
  • Vdirsyncer is now able to synchronize metadata of collections. Set metadata = ["displayname"] and run vdirsyncer metasync.
  • Packagers: Don’t use the GitHub tarballs, but the PyPI ones.
  • Packagers: is gone, and Makefile is included in tarballs. See the content of Makefile on how to run tests post-packaging.
  • verify_fingerprint doesn’t automatically disable verify anymore.

Version 0.5.2

released on 15 June 2015

  • Vdirsyncer now checks and corrects the permissions of status files.
  • Vdirsyncer is now more robust towards changing UIDs inside items.
  • Vdirsyncer is now handling unicode hrefs and UIDs correctly. Software that produces non-ASCII UIDs is broken, but apparently it exists.

Version 0.5.1

released on 29 May 2015

  • N.b.: The PyPI upload of 0.5.0 is completely broken.
  • Raise version of required requests-toolbelt to 0.4.0.
  • Command line should be a lot faster when no work is done, e.g. for help output.
  • Fix compatibility with iCloud again.
  • Use only one worker if debug mode is activated.
  • verify=false is now disallowed in vdirsyncer, please use verify_fingerprint instead.
  • Fixed a bug where vdirsyncer’s DAV storage was not using the configured useragent for collection discovery.

  • Support for client certificates via the new auth_cert parameter, see issue #182 and pull request #183.
  • The icalendar package is no longer required.
  • Several bugfixes related to collection creation.

Version 0.4.3

released on 20 February 2015

  • More performance improvements to singlefile-storage.
  • Add post_hook param to filesystem-storage.
  • Collection creation now also works with SabreDAV-based servers, such as Baikal or ownCloud.
  • Removed some workarounds for Radicale. Upgrading to the latest Radicale will fix the issues.
  • Fixed issues with iCloud discovery.
  • Vdirsyncer now includes a simple repair command that seeks to fix some broken items.

Version 0.4.2

released on 30 January 2015

  • Vdirsyncer now respects redirects when uploading and updating items. This might fix issues with Zimbra.
  • Relative status_path values are now interpreted as relative to the configuration file’s directory.
  • Fixed compatibility with custom SabreDAV servers. See issue #166.
  • Catch harmless threading exceptions that occur when shutting down vdirsyncer. See issue #167.
  • Vdirsyncer now depends on atomicwrites.
  • Massive performance improvements to singlefile-storage.
  • Items with extremely long UIDs should now be saved properly in filesystem-storage. See issue #173.

Version 0.4.1

released on 05 January 2015

  • All create arguments from all storages are gone. Vdirsyncer now asks if it should try to create collections.
  • The old config values True, False, on, off and None are now invalid.
  • UID conflicts are now properly handled instead of ignoring one item. Card- and CalDAV servers are already supposed to take care of those though.
  • Official Baikal support added.

Version 0.4.0

released on 31 December 2014

  • The passwordeval parameter has been renamed to password_command.
  • The old way of writing certain config values such as lists is now gone.
  • Collection discovery has been rewritten. Old configuration files should be compatible with it, but vdirsyncer now caches the results of the collection discovery. You have to run vdirsyncer discover if collections were added or removed on one side.
  • Pair and storage names are now restricted to certain characters. Vdirsyncer will issue a clear error message if your configuration file is invalid in that regard.
  • Vdirsyncer now supports the XDG-Basedir specification. If the VDIRSYNCER_CONFIG environment variable isn’t set and the ~/.vdirsyncer/config file doesn’t exist, it will look for the configuration file at $XDG_CONFIG_HOME/vdirsyncer/config.
  • Some improvements to CardDAV and CalDAV discovery, based on problems found with FastMail. Support for .well-known-URIs has been added.

Version 0.3.4

released on 8 December 2014

  • Some more bugfixes to config handling.

Version 0.3.3

released on 8 December 2014

  • Vdirsyncer now also works with iCloud. Particularly collection discovery and etag handling were fixed.
  • Vdirsyncer now encodes Cal- and CardDAV requests differently. This hasn’t been well-tested with servers like Zimbra or SoGo, but isn’t expected to cause any problems.
  • Vdirsyncer is now more robust regarding invalid responses from CalDAV servers. This should help with future compatibility with Davmail/Outlook.
  • Fix a bug when specifying item_types of caldav in the deprecated config format.
  • Fix a bug where vdirsyncer would ignore all but one character specified in unsafe_href_chars of caldav and carddav.

Version 0.3.2

released on 3 December 2014

  • The current config format has been deprecated, and support for it will be removed in version 0.4.0. Vdirsyncer warns about this now.

Version 0.3.1

released on 24 November 2014

  • Fixed a bug where vdirsyncer would delete items if they’re deleted on side A but modified on side B. Instead vdirsyncer will now upload the new items to side A. See issue #128.
  • Synchronization continues with the remaining pairs if one pair crashes, see issue #121.
  • The processes config key is gone. There is now a --max-workers option on the CLI which has a similar purpose. See pull request #126.
  • The Read The Docs-theme is no longer required for building the docs. If it is not installed, the default theme will be used. See issue #134.

Version 0.3.0

released on 20 September 2014

Version 0.2.5

released on 27 August 2014

  • Don’t ask for the password of one server more than once and fix multiple concurrency issues, see issue #101.
  • Better validation of DAV endpoints.

Version 0.2.4

released on 18 August 2014

  • Include workaround for collection discovery with latest version of Radicale.
  • Include metadata files such as the changelog or license in source distribution, see issue #97 and issue #98.

Version 0.2.3

released on 11 August 2014

  • Vdirsyncer now has a --version flag, see issue #92.
  • Fix a lot of bugs related to special characters in URLs, see issue #49.

Version 0.2.2

released on 04 August 2014

  • Remove a security check that caused problems with special characters in DAV URLs and certain servers. On top of that, the security check was nonsensical. See issue #87 and issue #91.
  • Change some errors to warnings, see issue #88.
  • Improve collection autodiscovery for servers without full support.

Version 0.2.1

released on 05 July 2014

  • Fix bug where vdirsyncer shows empty addressbooks when using CardDAV with Zimbra.
  • Fix infinite loop when password doesn’t exist in system keyring.
  • Colorized errors, warnings and debug messages.
  • vdirsyncer now depends on the click package instead of argvard.

Version 0.2.0

released on 12 June 2014

  • vdirsyncer now depends on the icalendar package from PyPI, to get rid of its own broken parser.
  • vdirsyncer now also depends on requests_toolbelt. This makes it possible to guess the authentication type instead of blankly assuming basic.
  • Fix a semi-bug in caldav and carddav storages where a tuple (href, etag) instead of the proper etag would have been returned from the upload method. vdirsyncer might do unnecessary copying when upgrading to this version.
  • Add the storage singlefile. See issue #48.
  • The collections parameter for pair sections now accepts the special values from a and from b for automatically discovering collections. See Pair Section.
  • The read_only parameter was added to storage sections. See Storage Section.

Version 0.1.5

released on 14 May 2014

  • Introduced changelogs
  • Many bugfixes
  • Many doc fixes
  • vdirsyncer now doesn’t necessarily need UIDs anymore for synchronization.
  • vdirsyncer now aborts if one collection got completely emptied between synchronizations. See issue #42.
