1.3.0 (06/06/2017)

The 1.3.0 stable release, with no addition changes since the rc4 release!

A quick summary of exciting changes since the 1.2.x branch:

• Pants’ python backend has been overhauled and modernized to support caching, and to lower the latency of re-running tests after a code edit.

• Pants now uses a native code ‘engine’ implemented in rust, which unlocks significant performance improvements in the future.

• A daemon that caches BUILD file parsing and file fingerprinting (and more to follow!) is now ready for alpha testing (with two significant caveats).

• A default set of implicit_sources can now be manually enabled to further reduce BUILD file boilerplate. This option should become the default in the next stable release.

• The Zinc incremental scala compiler is now at 1.0.0, with improved incremental behaviour.

• Style-related tasks that used to be in the compile goal have moved to a new lint goal.

• The fmt goal was added, with support for scalafmt, gofmt, and python isort to start.

• Support for yarnpkg in the node contrib module.

• Support for relative ‘jar’ declarations, to allow for committing jars in your repo (if that’s your bag!)

• A contrib module for errorprone was added.

• Direct support for scalatest tests in the pants JVM test runner.

See the rest of this page for the complete list of changes.

A weekly unstable release.

This release brings the new pantsbuild.pants.contrib.jax_ws plugin that can generate Java client stubs from WSDL sources. Thanks to Chris Heisterkamp for this!

The release also pulls in a few fixes for python requirement resolution in the PEX library used by pants. In the past, the python-setup.resolver_allow_prereleases configuration option would not always be resepected; it now is. Additionally, a longstanding bug in transitive requirement resolution that would lead to erroneous ‘Ambiguous resolvable’ errors has now been fixed. Thanks to Todd Gardner and Nathan Butler for these fixes!

1.3.0.dev15 (4/03/2017)

A weekly unstable release, delayed by a week!

This release contains multiple significant new features, including the “exports” literal on JVM targets (to better support common cases in repositories using “strict_deps”), the initial release of the new python backend with caching support, a new “outdated.ivy” goal to report which JVM dependencies are out of date, speedups for go builds, and last but not least: the first release with the v2 engine enabled by default (to enable stabilization of the pants daemon before the 1.3.x stable releases).
