## 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

- Removed remoteStorage support, see issue #647.

- Fixed test failures caused by latest requests version, see issue #660.

## Version 0.16.0

released on 2 June 2017

- Strip `METHOD:PUBLISH` added by some calendar providers, see issue #502.

- Fix crash of Google storages when saving token file.

- 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.

- Packagers: Reference `systemd.service` and `systemd.timer` unit files are provided. It is recommended to install these as documentation if your distribution is systemd-based.

## Version 0.15.0

released on 28 February 2017

- Deprecated syntax for configuration values is now completely rejected. All values now have to be valid JSON.

- A few UX improvements for Google storages, see issue #549 and issue #552.

- Fix collection discovery for `google_contacts`, see issue #564.

- iCloud is now tested on Travis, see issue #567.

## Version 0.14.1

released on 05 January 2017

- `vdirsyncer repair` no longer changes “unsafe” UIDs by default, an extra option has to be specified. See issue #527.

- A lot of important documentation updates.

## Version 0.14.0

released on 26 October 2016

- `vdirsyncer sync` now continues other uploads if one upload failed. The exit code in such situations is still non-zero.

- Add `partial_sync` option to pair section. See the config docs.

- Vdirsyncer will now warn if there’s a string without quotes in your config. Please file issues if you find documentation that uses unquoted strings.

- Fix an issue that would break khal’s config setup wizard.

## Version 0.13.1

released on 30 September 2016

- 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

- Fix a crash for Google and DAV storages. See pull request #492.

- Fix an URL-encoding problem with DavMail. See issue #491.

## Version 0.12

released on 19 August 2016

- `singlefile` now supports collections. See pull request #488.

## Version 0.11.3

released on 29 July 2016

- Default value of `auth` parameter was changed from `guess` to `basic` to resolve issues with the Apple Calendar Server (issue #457) and improve performance. See issue #461.

- Packagers: The `click-threading` requirement is now `>=0.2`. It was incorrect before. See issue #478.

- Fix a bug in the DAV XML parsing code that would make vdirsyncer crash on certain input. See issue #480.

- Redirect chains should now be properly handled when resolving `well-known` URLs. See pull request #481.

## Version 0.11.2

- Fix typo that would break tests.

## Version 0.11.1

released on 15 June 2016

- Fix a bug in collection validation.

- Fix a cosmetic bug in debug output.

- Various documentation improvements.

## Version 0.11.0

released on 19 May 2016

- Discovery is no longer automatically done when running `vdirsyncer sync`. `vdirsyncer discover` now has to be explicitly called.

- 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

- New storage types `google_calendar` and `google_contacts` have been added.

- New global command line option –config, to specify an alternative config file. See issue #409.

- The `collections` parameter can now be used to synchronize differently-named collections with each other.

- Packagers: The `lxml` dependency has been dropped.

- XML parsing is now a lot stricter. Malfunctioning servers that used to work with vdirsyncer may stop working.

## Version 0.9.3

released on 22 March 2016

- `singlefile` and `http` now handle recurring events properly.

- Fix a typo in the packaging guidelines.

- Moved to `pimutils` organization on GitHub. Old links should redirect, but be aware of client software that doesn’t properly handle redirects.

## Version 0.9.2

released on 13 March 2016

- Fixed testsuite for environments that don’t have any web browser installed. See pull request #384.

## Version 0.9.1

released on 13 March 2016

- Removed leftover debug print statement in `vdirsyncer discover`, see commit `3d856749f37639821b148238ef35f1acba82db36`.

- `metasync` will now strip whitespace from the start and the end of the values. See issue #358.

- New `Packaging Guidelines` have been added to the documentation.

## Version 0.9.0

released on 15 February 2016

- The `collections` parameter is now required in pair configurations. Vdirsyncer will tell you what to do in its error message. See issue #328.

## Version 0.8.1

released on 30 January 2016

- Fix error messages when invalid parameter fetching strategy is used. This is important because users would receive awkward errors for using deprecated `keyring` fetching.

## Version 0.8.0

released on 27 January 2016

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

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

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

## Version 0.7.5

released on 23 December 2015

- Fixed a bug in `remotestorage` that would try to open a CLI browser for OAuth.

- Fix a packaging bug that would prevent vdirsyncer from working with newer lxml versions.

## Version 0.7.4

released on 22 December 2015

- Improved error messages instead of faulty server behavior, see issue #290 and issue #300.

- Safer shutdown of threadpool, avoid exceptions, see issue #291.

- Fix a sync bug for read-only storages see commit `ed22764921b2e5bf6a934cf14aa9c5fede804d8e`.

- Etag changes are no longer sufficient to trigger sync operations. An actual content change is also necessary. See issue #257.

- `remotestorage` now automatically opens authentication dialogs in your configured GUI browser.

- Packagers: `lxml>=3.1` is now required (newer lower-bound version).

## Version 0.7.3

released on 05 November 2015

- Make remotestorage-dependencies actually optional.

## Version 0.7.2

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 `setup.py` 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: `build.sh` 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.

## Version 0.4.4

released on 12 March 2015

- 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

- Add `verify_fingerprint` parameter to `http`, `caldav` and `carddav`, see issue #99 and pull request #106.

- Add `passwordeval` parameter to General Section, see issue #108 and pull request #117.

- Emit warnings (instead of exceptions) about certain invalid responses from the server, see issue #113. This is apparently required for compatibility with Davmail.

## 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.
