2023.11.0

Released on November 3rd, 2023

Documentation for this release

A major release introducing several new features to significantly improve the user experience.

New features

• Cotainr now features a much improved formatting of console output when running cotainr build, including options to set verbosity (--verbose/--quiet), directing the output to a log file (--log-to-file), colored output, filtering of output from Conda/Singularity to fix the console output being messed up by attempted line updates, and finally the introduction of a spinner prepended to the latest output message, when cotainr is doing work in the background, PR#45.
• When including a conda environment in your container (via cotainr build ... --conda-env=...), you are now required to explicitly accept the Miniforge license terms as we use Miniforge to bootstrap the conda environment. This license (along with all other required licenses, if any) may be accepted on beforehand by specifying the option --accept-licenses when running cotainr build ..., PR#40.
• The cotainr release notes now include links to the corresponding HTML documentation hosted on Read the Docs, PR#38.

Bug fixes

• Cotainr now correctly recognizes and supports the SingularityCE variant of the Singularity runtime, PR#42.
• Minor documentation fixes, PR#34, PR#39, PR#43.

Maintenance updates

• Cotainr now implements PEP394 to always invoke the python interpreter as "python3", PR#33.
• The LUMI PyTorch example has been updated to match the state of LUMI as of 09/2023, PR#41.
