* **26 Mar 2013:** Release 2.3 of Snakemake. The parser has been rewritten completely to increase the flexibility. The first yield is support for nesting rules into conditional statements and for-loops (see [here](https://bitbucket.org/johanneskoester/snakemake/src/master/tests/test_conditional/Snakefile) for an example). Second, the new locking mechanism has been improved to only report a lock when a running workflow uses conflicting files in the same directory. Further, incomplete files should be reported less often since cases where the file was correctly deleted by Snakemake after a failing job are now omitted. Finally some bugs were fixed and special thanks go to Marcel Martin and Hyeshik Chang for contributing patches.
