[4.8.0] - 2018-03-13¶
- Integration with CWL: the
cwldirective allows to use CWL tool definitions in addition to shell commands or Snakemake wrappers.
- A global
singularitydirective allows to define a global singularity container to be used for all rules that don’t specify their own.
- Singularity and Conda can now be combined. This can be used to specify the operating system (via singularity), and the software stack (via conda), without the overhead of creating specialized container images for workflows or tasks.

[4.4.0] - 2017-12-21¶
- A new shadow mode (minimal) that only symlinks input files has been added.
- The default shell is now bash on linux and macOS. If bash is not installed, we fall back to sh. Previously, Snakemake used the default shell of the user, which defeats the purpose of portability. If the developer decides so, the shell can be always overwritten using shell.executable().
- Snakemake now requires Singularity 2.4.1 at least (only when running with –use-singularity).
- HTTP remote provider no longer automatically unpacks gzipped files.
- Fixed various smaller bugs.

[4.0.0] - 2017-07-24¶
- Cloud computing support via Kubernetes. Snakemake workflows can be executed transparently in the cloud, while storing input and output files within the cloud storage (e.g. S3 or Google Storage). I.e., this feature does not need a shared filesystem between the cloud notes, and thereby makes the setup really simple.
- WebDAV remote file support: Snakemake can now read and write from WebDAV. Hence, it can now, e.g., interact with Nextcloud or Owncloud.
- Support for default remote providers: define a remote provider to implicitly use for all input and output files.
- Added an option to only create conda environments instead of executing the workflow. # ## Changed
- The number of files used for the metadata tracking of Snakemake (e.g., code, params, input changes) in the .snakemake directory has been reduced by a factor of 10, which should help with NFS and IO bottlenecks. This is a breaking change in the sense that Snakemake 4.x won’t see the metadata of workflows executed with Snakemake 3.x. However, old metadata won’t be overwritten, so that you can always go back and check things by installing an older version of Snakemake again.
- The google storage (GS) remote provider has been changed to use the google SDK. This is a breaking change, since the remote provider invocation has been simplified (see docs).
- Due to WebDAV support (which uses asyncio), Snakemake now requires Python 3.5 at least.
- Various minor bug fixes (e.g. for dynamic output files).
[3.13.3] - 2017-06-23¶

snakemake --archive my-workflow.tar.gz. The archive contains all input files, source code versioned with git and all software packages that are defined via conda environments. Hence, the archive allows to fully reproduce a workflow on a different machine. Such an archive can be uploaded to Zenodo, such that your workflow is secured in a self-contained, executable way for the future. # ## Changed
- Improved logging.
- Reduced memory footprint.
- Added a flag to automatically unpack the output of input functions.
- Improved handling of HTTP redirects with remote files.
- Improved exception handling with DRMAA.

- Snakemake now warns when using relative paths starting with “./”.
- The option -R now also accepts an empty list of arguments.
- Bug fix when handling benchmark directive.
- Jobscripts exit with code 1 in case of failure. This should improve the error messages of cluster system.
- Fixed a bug in SFTP remote provider.
[3.8.0] - 2016-08-26¶
- Wildcards can now be constrained by rule and globally via the new
wildcard_constraintsdirective (see the docs).
- Subworkflows now allow to overwrite their config file via the configfile directive in the calling Snakefile.
- A method
log_fmt_shellin the snakemake proxy object that is available in scripts and wrappers allows to obtain a formatted string to redirect logging output from STDOUT or STDERR.

- In the API, multiple
cluster_configpaths can be given as a list, alternatively to the previous behaviour of expecting one string for this parameter.
- When submitting cluster jobs (either through
--drmaa), you can now use
--max-jobs-per-secondto limit the number of jobs being submitted (also available through Snakemake API). Some cluster installations have problems with too many jobs per second.
