Compatibility

A quick disclaimer on backwards-compatibility for Toyplot users:

Toyplot follows the Semantic Versioning standard for assigning version numbers in a way that has specific meaning. Toyplot version numbers use <major>.<minor>.<patch> numbering. Releases with different major API numbers are API incompatible. Minor version numbers signify new features that are backwards-compatible with the current major version. Patch numbers indicate bug fixes and documentation changes that are backwards-compatible with the current major and minor version.

Python Versions

Past versions of Toyplot supported Python 2 and Python 3 with a single code base. However, Python 2 has not been maintained since 2020 (https://pythonclock.org), and Toyplot stopped supporting Python 2 on December 31st, 2018. The Toyplot 0.18 branch was the final release that included Python 2 support … beginning with Toyplot 0.19, the portability code was removed and our automated regression tests are only run using Python 3. Of course, developers are free to continue working with the 0.18 branch if they need to support Python 2, and we will consider pull requests for the 0.18 branch if they arise.
