The Python development community concurrently supports multiple version of the Python programming language. These are in various states such as "prerelease", "bugfix", "security", or "end-of-life". For example version 3.12 is currently in "bugfix" while 3.8 is the oldest still receiving security updates. The cadence of future release is currently governed by PEP 602 – Annual Release Cycle for Python

Today we are excited to announce that Klaviyo has become the first Platinum sponsor of the Pants project via the corporate sponsorship program! This is one of the first such sponsorships through our new Open Source Sponsorship program, through which we are trying to support the open source projects we depend on. While the core development and maintenance of Pants is volunteer driven, there are costs involved with maintaining and distributing such a large piece of software, costs which far too often are covered by individual volunteers. We benefit enormously from this project and want to help contribute to its ongoing success.

We are pleased to announce Pants 2.21.0, the latest release of Pantsbuild, the scalable and ergonomic build system. To update, set pants_version = "2.21.0" in your pants.toml. If you're not using Pants yet, get started now.

Highlights in 2.21 include:

• 🧪 All backends now support [test].attempts_default
• ⚡ Pants internal manipulation of Python dependencies by way of Pex is now substantially faster in many cases.
• 📜 The __defaults__ symbol will now set default values for generated targets too. For instance, __defaults__({python_source: dict(skip_black=True)}) will now apply to the python_source targets generated by a python_sources target, without having to write __defaults__({(python_source, python_sources): ...})
• ♻ When running in CI, Pants will output a command to rerun only the failed tests.
• 🐍 All built in lockfiles are now Python 3.12 ready.
• 🚡 As part of regenerating lockfiles for Python 3.12, the default version of most builtin Python tools has been updated.
• 🐳 The cache_from field on docker_image now supports multiple values.
• 🏜 The experimental-deploy goal now has built-in support for the --dry-run option.
• 🪜 Scalafix can now be run by Pants using the new pants.backend.experimental.scala.lint.scalafix backend.
• 📈 And lots of smaller features, update, bugfixes, and general improvements

We are pleased to announce Pants 2.20.0, the latest release of Pantsbuild, the scalable and ergonomic build system. To update, set pants_version = "2.20.0" in your pants.toml. If you're not using Pants yet, get started now.

Highlights in 2.20 include:

• ⚡ Support for the Ruff formatter, for both BUILD files and normal Python files.
• 🔒 Built-in support for Terraform lockfiles.
• 📁 Support for more remote-caching providers: file system and GitHub Actions Cache.
• 🪥 New helpers for defining "adhoc" code-quality tools, without requiring a full plugin.
• ☕ JVM third-party artifacts can now be read from pom.xml files, and other related improvements.
• 🐿 Go 1.22 can now be used.
• 🥚 Several features of the Pex tool are now exposed by Pants including sh_boot executable, and check.
• ⚠ Pex's emit_warnings now works as advertised and comes with a global option.
• 🐋 Experimental support for Podman with pants.backend.experimental.docker.podman.
• 📈 And lots of smaller features, bugfixes, and general improvements

The 2.15 series represents the biggest change to Pants since version 2.0, and we're excited to share how it can let you complete more workflows, more easily, in more places. Including cross-platform builds, containerized builds with Docker, and easier configuration for local builds…

Highlights include: less boilerplate via hierarchical defaults for target field values, better Golang monorepo support, with multiple go.mods, do more of your workflows in Pants with the experimental deploy goal (with initial support for Helm), and much more…

We're pleased to announce Pants 2.13.0. Highlights include better command line arguments for file sets, improved JVM support, easier access to parallel execution in CI, and lower barriers to adoption for Python projects that currently use existing distribution and build tools.

Pants 2.8 adds Autoflake & Pyupgrade, Docker publishing, Golang, PEP 517 publishing, and Google Cloud Functions

Why Pants for Golang? A consistent interface for all languages & tools, integration with Git + advanced project introspection, and remote caching and execution. All with minimal boilerplate.

Successful open source projects are full of tradeoffs between purity vs. pragmatism. We often remind ourselves "Do not let perfect be the enemy of good".

There are so many tools in the Python development ecosystem. Installing, configuring and orchestrating them—all while not re-executing work unnecessarily—is a hard problem, especially as your codebase grows.

Fortunately, there is now a tailor-made (pun intended) solution: Pants v2!
