Taskwarrior, Taskserver, Tasksh and Timewarrior have many features. With each release new features are added, and sometimes features are removed. A feature may be removed if it has been superseded by something better, is no longer relevant, or is very troublesome.
With the Taskwarrior command line syntax becoming more formal and regular with every release, there will be a corresponding set of changes that remove ambiguous command line syntax, and add consistent syntax.
Before a feature is removed, it is deprecated, where possible. This means that it will appear on this list, in one release, and be removed in an unspecified later release. Deprecation acts as an early warning for disappearing functionality, giving users time to adapt or complain.
When a feature is removed, any related configuration settings are
also removed. You can see if your
any obsolete settings by using the
$ task show ...
show command highlights various problems.
Starting with Taskwarrior 2.3.0, the
merge commands are deprecated,
and gone from 2.4.0. The
sync command in 2.3.0
replaces this functionality.
Starting in 2.4.0, shadow files are replaced by an equivalent hook mechanism.
Attribute modifiers such as
are all deprecated starting with version 2.4.0. In the example
above, the replacement is an algebraic expression,
project ~ ^ab, which uses the
match operator, and
^Ab which is a regular expression.
Simple words being interpreted as search terms is deprecated in
2.4.0 and will be removed in a future release. The preferred
task /pattern/ ....
limit:20 pseudo attribute looks like a task
attribute, but is just syntactic sugar. It is deprecated and
will be replaced by
rc.limit in a future release.
Urgency inheritance changes with 2.4.5, and this settings will no longer be used.
The non-extended formats are just strings of numbers without
separators. Here is an extended date
here is the unextended date
20150625, which looks
like a number or even an abbreviated UUID. Here is an extended
12:34:56, and an unextended time
123456, with the same issue. The non-extended forms
will be removed.
_uuids helper commands are deprecated in favor of
DUETODAYdeprecated since 2.6.0
DUETODAY virtual tag is a synonym for the more
TODAY virtual tag.
1deprecated since 2.6.0
Deprecated use of alternate Boolean configuration settings. Use values "0" for off, and "1" for on. Avoid used of "on", "off", "true", "t", "false", "f", "yes", "y", "no", "n".
The dom references
context.height are replaced by
Taskserver initially supported the
client.deny settings which filtered connections.
The intention was to be able to decline misbehaving clients.
This has proved to be a configuration problem for some, and the
mechanism is easily spoofed, so it will be removed.
