The syntax now allows for time differences larger than 99:99. (issue #14)

arbtt-dump can now show the data in other formats as well, as suggested by Waldir Pimenta (option --format). This includes a human-readale output and JSON.

New option --last of arbtt-dump.

arbtt-recover can handle larger datasets with a reasonable amount of memory.

When dumping samples with arbtt-stats or arbtt-dump (in human-readable mode), times are printed in the local time zone, as suggested by Oren Gampel.

arbtt-capture now supports the option --dump for development and debugging purposes.

The name of the current desktop (or workspace) is also recorded, and available as $desktop (issue #1).

Two bugs in the parser were fixed (issue #4 and issue #5).

arbtt-stats can print reports split by time interval, using the --for-each option.

arbtt-stats can print the actual samples selected, with --dump-samples.

Support for GHC-7.8 was added, with help from Jayesh Kumar Gupta (issue #8).

Arbtt now has a proper testsuite integrated into Cabal, and an automated test infrastructure on Travis.

Waldir Pimenta contributed a new web page, hosted at arbtt.nomeata.de.

Make sure that the log file is only readable by the current user. Thanks to Joey Hess for pointing that out.

Show a progress bar in arbtt-stats.

GHC-7.6 compatibility, thanks to Isaac Dupree.

Added missing module to the packages.

Massive memory footprint reduction, due to processing the data in one run. See my blog post for technical information.

Performance improvements.

Support comparing a string to a list of strings, or matching it against a list ofregular expressions.

Add a warning whtn the system locale is not supported.

Allwo RTS options to be passed to the arbtt binaries.

GHC 7.4 compatibility.

Performance improvements.

The command arbtt-capture now supports the --logfile.

New report “intervals”, available using arbtt-stats --intervals.

The paramters --exclude and --include of arbtt-stats can match categories as well as tags.

Bugfix: Numbers in tag names are no longer replaced by an underscore.

New paramters --output-exclude and --output-include of arbtt-stats.

New command arbtt-import, which imports the output from arbtt-dump.

The command arbtt-stats now supports the --logfile and --categorizefile as well. (Martin Kiefel)

The command arbtt-stats now supports the csv (comma-separated values) and tsv (TAB-separated values) report output formats in addition to text. (Muharem Hrnjadovic)

Unicode is handled correctly in regular expressions.

Improved date-handling functions for categorize.cfg. (Sergey Astanin)

Bugfix: Added missing modules to the cabal file.

Implement a custom compression method greatly reduce the file size of the log file. Run arbtt-capture to compress the previous samples as well.

Bugfix: Correctly parse a tag name containing a colon when passed to arbtt-stats --exclude.

Bugfix: Only warn once when the _NET_CLIENT_LIST X property is not set for the root window.

Use fetchName from xmonad instead of xFetchName, as it works with unicode characters in window titles.

Implement option --logfile to arbtt-dump.

New command arbtt-recover to rescue data from a proken data log file.

Actually include this documentation in the released tarball.

Write this documentation

Drop dependency on setlocale: Copy the SetLocale module.

Drop dependency on tabular: Implement custom table rendering code.

In the absence of _NET_CLIENT_LIST, look for application windows as children of the root windows. This should work for users of window managers like i3 without EWHM support.

Implement option --each-categories to arbtt-stats

Eliminate one possible cause for crashes of arbtt-capture.

Switch to binary log file format, for greatly increased speed

arbtt-capture will automatically detect and convert log files in the old format.

Add option --filter to arbtt-stats

Add option --sample-rate to arbtt-capture

Introduce time-base variables $time and $sampleage

Use setlocale to get umlauts in window titles correctly

Be smarter when figuring out what window is active. Thanks to CJ van den Berg for investigating the issue.

Read _NET_CLIENT_LIST for the list of applications, for compatibility with window managers such as metacity

Off-By-Ten error in the time display

Correctly show total number of records in --information
