ChangeLog

------ current release ---------------------------

3.4.2 -

- Sorting task lists randomly is now supported with configuration such as
  `report.<report-name>.sort = random` (#3940)
- Handling for tags in a "tags" column after `task edit` is fixed (#3911)
- `tags.none:` works correctly (#3877)

  longer prompts to create `.taskrc`. (#3888)

------ old releases ------------------------------

3.4.1 -

- The nagging to read `task news` has been fixed.

3.4.0 -

- Where possible, the task DB is now opened in read-only mode, which improves
  performance. This is the case for reports (task lists) only when the `gc`
  config is false.
- An updated version of corrosion fixes build errors trying to find the Rust
  toolchain.

3.2.0 -

 - Support for the journal in `task info` has been restored (#3671) and the
   task info output no longer contains `tag_` values (#3619).
 - The `rc.weekstart` value now affects calculation of week numbers in
   expressions like `2013-W49` (#3654).
 - Build-time flag `ENABLE_TLS_NATIVE_ROOTS` will cause `task sync` to use the
   system TLS roots instead of its built-in roots to authenticate the server (#3660).
 - The output from `task undo` is now more human-readable. The `undo.style`
   configuraiton option, which has had no effect since 3.0.0, is now removed (3672).
 - Fetching pending tasks is now more efficient (#3661).

3.1.0 -

 - Support for `task purge` has been restored, and new support added for automatically
   expiring old tasks. (#3540, #3546, #3556)
 - `task news` is now better behaved, and can be completely disabled.
 - Multiple imports of the same UUID will now generate a warning. (#3560)
 - The `sync.server.url` config replaces `sync.server.origin` and allows a URL
   containing a path. (#3423)
 - The new `bubblegum-256.theme` has improved legibility and contrast over
   others. (#3505)
 - Warnings regarding `.data` files are only show for reports. (#3473)
 - Inherited urgency is correctly calculated to make parents more urgent than
   children (#2941)

3.0.2 -

- Fix an accidentally-included debug print which polluted output of
  reports with the Taskwarrior version (#3389)

3.0.1 -

- Fix an error in creation of the 3.0.0 tarball which caused builds to fail (#3302)
- Improvements to `task news`, including notes for the 3.0.0 release
- Minor improvements to documentation and error handling
- Fix incorrect task ID of 0 when using hooks (#3339)
- Issue a warning if .data files remain (#3321)

3.0.0 -

- [BREAKING CHANGE] the sync functionality has been rewritten entirely, and
  no longer supports taskserver/taskd. Instead, the recommended solution is
  a cloud-storage backend, although `taskchampion-sync-server` is also
  available.

  See https://taskwarrior.org/docs/upgrade-3/ for information on upgrading to
  Taskwarrior 3.0.

  The following config options are no longer supported:
  - `debug.tls`
  - `taskd.ca`
  - `taskd.certificate`
  - `taskd.ciphers`
  - `taskd.credentials`
  - `taskd.key`
  - `taskd.server`
  - `taskd.trust`

  The Taskwarrior build no longer requires GnuTLS. The build option
  `ENABLE_SYNC=OFF` is also no longer supported; sync support is always built
  in.

  by using "task list project.isnt:foo project.isnt:bar" (thanks to John
  Florian).

  epoch numbers instead of dates (thanks to Cory Donnelly).
- Fixed bug #369 which prevented the config command from setting quoted or
  unquoted multi-word values (thanks to Richard Querin).
- Fixed bug #370 which prevented the removal of a due date from a task,
  mis-identifying the task as recurring just because it had a due date
  (thanks to John Florian).

- Fixed bug #249 that caused annotations with the same date to be lost after
  a "task edit" command (thanks to Federico Hernandez).
- Fixed bug #250 whereby rc.dateformat was not observed when parsing the
  creation date of an annotation (thanks to Federico Hernandez).
- Fixed bug #251 whereby the presence of annotations cause the .hasnt attribute
  modifier to not work (thanks to John Florian).

  part of the description, despite what they otherwise might mean.
- Removed support for the obsolete task file format 1 (never released).
- Fixed bug that allowed blank annotations to be added (thanks to Bruce
  Dillahunty).
- Supports negative tag filters, so that (task list +foo -bar) now filters
  tasks that have the "foo" tag, but do not have the "bar" tag (thanks to
  Chris Pride).
- Custom reports now support a more compact form of the "age" column,
  called "age_compact" (thanks to T. Charles Yun).

  (thanks to Federico Hernandez).
- Now asks the user to confirm large changes if configuration variable
  'confirmation' is set to 'yes'.  A large change is one that completely

  printed before and after report output, with the 'color.header' and
  'color.footnote' configuration variables.
- Now supports the 'limit' attribute, to control the number of tasks that
  are shown, for example: "task list limit:10".
- Now supports a debug mode that can be used to generate helpful information
  when reporting a problem.  Just run the command with "task rc.debug:on ..."
  and diagnostics will be generated that will help pinpoint a problem.
- The new "undo" command replaces the old "undo" and "undelete" command
  with a complete undo stack that can rollback all changes.
- While waiting for a file lock, task states the reason for the delay.
- Now supports a 'waiting' state that causes tasks to not appear until
  a certain date, for example "task <ID> wait:<date>".  The task
  will then not show up on any report (except 'all') until that date.
- The "active", "completed", "overdue" and "next" reports are now custom
  reports, and therefore modifiable.

- Task allows commands that require an ID to now be given a sequence, which
  is a set of IDs.  This allows commands like "task delete 1 2 5-10,12".
- Fixed bug in the ghistory report, which caused it to only show a new
  month if a task was added during that month.
- New command "duplicate" which allow existing task(s) to be duplicated,

  data.location specified otherwise (thanks to Federico Hernandez).
- New "edit" command that fires up a text editor (uses 'editor' configuration
  variable, $VISUAL or $EDITOR environment variable) and allows direct
  editing of all editable task details.

  and it excludes annotations.
- A task can now be upgraded to a recurring task by adding a recurrence
  frequency, a due date, and an optional until date.
- When a recurring task is modified, all other instances of the recurring
  task are also modified.
- Custom reports now support user-specified column labels (thanks to T.
  Charles Yun).
- Task can now import tasks from a variety of data formats, including task
  export files from versions 1.4.3 and earlier, versions 1.5.0 and later,
  todo.sh 2.x, CSV, plain text and task command line.  See online docs for
  full details.
- Export was including 'id' in the column header even though it was not
  included in the data.
- The task file format has changed slightly.  Please back up your task

  changes.  Useful for integrating with "Samurize".
- Task now displays a message whenever a shadow file is updated, if the
  "shadow.notify" configuration variable is set "on".
- Bug: adding a task with a \n, \r or \f in it now fails properly.
- Removed "usage" command, and support for "command.logging" configuration
  variable.
- Added documentation for Shadow files.
