Robot Framework 3.0 alpha 2 is the second preview of the next Robot Framework major version. The biggest enhancement it contains is Python 3 support, but also new generic robot start-up script have been introduced.
Biggest change in alpha 2 over alpha 1 is improvement in the execution speed when using listeners. The issue list at the end of full release notes mentions for each issue whether it came in alpha 1 or 2.
Source distribution is available at PyPI and pip users can simply run pip install --upgrade --pre robotframework to install or upgrade to the latest release or pip install robotframework==3.0a2 to install exactly this version.
Separate Windows installers are not created and the plan is not to create them even for final releases in the future (#2218). The standalone jar distribution can be created and added here if there are requests, but we only upload final releases to the Maven central.
Robot Framework 3.0 alpha 2 was released on Thursday December 10, 2015.
