Welcome to the Q1 '23 edition of the Bazel community update! Our goal is to build a stronger community and encourage more participation by keeping you informed on what’s happening in this space.
Bazel 6.1.0 was released in March ‘23, along with subsequent patch release 6.1.1. We thank community members for their contributions. Bazel 6.2.0 is currently in the works and open for PR submissions. It is scheduled to be released in early June ‘23.
Bazel Community Experts
The Bazel Community Experts program is an important part of the Bazel ecosystem. It has helped create a thriving community of Bazel build practitioners by providing training and support to partners who collectively employ over 100 Bazel engineers and educate and train over 1,000 engineers with Bazel skills on an annual basis.
Earlier this year, we met with the partners to collect feedback on how to accelerate the program. We were happy to hear the numerous positive impacts of this program and see the collaboration between the partners to help grow the Bazel ecosystem.
In 2023, we plan to expand the program to include product focus partners such as JetBrains* and also make it community managed through a Special Interest Group (SIG). We plan to create a Bazel Marketing SIG in Q2 ‘23 to empower the community to take leadership in building the program along with Google.
We will share more details on the SIG formation and participation in upcoming months. We are excited to see the continued growth of the Bazel community and to work with our partners to make Bazel the best open source build solution.
BazelCon 2023 and community monthly updates
We are currently planning our 2023 community outreach events and will share more details in Q2 ‘23. We are excited about the growth of community-led meetups to support training and skill development, and we are always happy to join in when possible. Please reach out to email@example.com if you would like to discuss how we can help make your event a success.
Office hours pilot
We have launched dedicated office hours to provide the Bazel team and community experts a forum to engage with users and contributors. This will run as a monthly pilot program on the upcoming dates:
You can submit your questions beforehand through this form and join the live office hours session here.
Contribute to a better Bazel
Release cadence survey
We’re currently collecting feedback on the Bazel LTS release cadence through a survey. The survey is still open, so please feel free to fill it out. Your feedback will be used to help determine the best release cadence for the Bazel community.
Platform API improvements
The Configurability team is seeking input on the next steps for improving the Platforms API. Please read the initial requirements document, add any comments or suggestions, and then fill out a survey to help the team decide on priorities.
Last year, we made significant changes to Bazel’s website to elevate overall developer experience and make it easier to contribute new content. This year, we aim to further improve Bazel’s documentation and eliminate common pain points. We published a blog post on how you can help support this effort.
Bazel Day 2023
Bazel Day 2023 was held on March 2 on Google Open Source Live. The following videos are available on-demand:
- Intro to Bazel by Radhika Advani and Sven Tiffe: New to Bazel? Learn how to get started with a quick overview of how Bazel is used, basic concepts, and a demo to build projects with Bazel.
- Managing external dependencies with Bzlmod by Xudong Yang: Dependencies are part of any build process. With the latest version of Bazel, the process for handling external dependencies has been reworked to better support external and transitive dependencies. This talk introduces Bzlmod and how you can begin to use it with your projects.
- Introduction to remote caching and execution with Bazel by Chi Wang and Tiago Quelhas: Did you know you can fast build and test with Bazel's remote caching and remote execution? In this session, you'll learn how to build even faster when building without the bytes.
- Bazel IntelliJ plugin by Mai Essa: Walkthrough of the Bazel IntelliJ plugin's features and capabilities.
Community Day in Israel
Wix Engineering and EngFlow hosted a Bazel Community Day in Israel on February 23. The community gathered for a Bazel newcomers' workshop and a series of talks ranging from Wix's remote execution migration to external dependency management. The following videos are available on-demand:
- Keynote by Helen Altshuler, CEO and Co-Founder of EngFlow
- How Wix migrated from one RBE provider to another with zero downtime by Zachi Nachshon, Backend Tech Lead at Wix
- Leading EngFlow Bazel workshop: build performance analysis & improvements by Antonio Di Stefano, Software Developer at EngFlow
- Managing external dependencies with Bzlmod by Xudong Yang, Software Engineer at Google
- Future of Bazel by Tobias Werth, Staff Software Engineer at Google
GitHub archive checksum outage: On January 30, a change in GitHub's source archive generation mechanism caused build errors for many Bazel users. We have published a blog post that provides more information about the issue and our recommendations. We would like to thank the community and GitHub product teams for their cooperation in resolving this issue quickly.
Bazel Central Registry: BCR was launched in January. As the default Bazel registry for the Bzlmod external dependency system, which entered general availability with Bazel 6.0, the BCR is the recommended place to publish and discover Bazel modules. Find more information in this blog post.
Bazel roadmap: We're thrilled to share our 2023 roadmap! Our next long term release (LTS), Bazel 7.0, is scheduled for late ‘23. Our focus for 2023 will be on improving the performance, features, and developer experience of Bazel. Some specific goals include:
- Migrating Java and C++ rules to Starlark so they can be developed independently of Bazel LTS release
- Supporting IntelliJ IDEA IDE releases in partnership with JetBrains*
- Making Bazel more user-friendly for Android app builds using the CLI
- Supporting secure supply chain integrity by supporting generation of data required to produce SBOM
We appreciate your feedback. Please check the roadmap for regular updates throughout the year.
Backlog clean up: Over the past few years, we have noticed several languishing issues and pull requests on repositories across the Bazel GitHub organization. Our goal is to close issues/PRs older than 6 months that haven't been addressed and are unlikely to be addressed at the current state, in order to sustainably manage and maintain the growing backlog. More information and implementation details can be found in our blog post.
GitHub Discussions: The Github Discussions feature has been enabled for the Bazel project, which provides a new space for our community members to have conversations, ask questions, and share answers, all without the need to open issues. Other channels like bazel-discuss and bazel-dev are still available. Please read our blog post for more information.
This is a space for the Bazel community voice. If there is anything interesting you are building or any updates you would like to highlight in future editions, please reach out to firstname.lastname@example.org.
