Release Notes

oapi-codegen/oapi-codegen (github.com/oapi-codegen/oapi-codegen/v2)

v2.6.0: : 7th anniversary release 🎂

Compare Source

For those that aren't aware, 7 years ago to the day, oapi-codegen was born!

(Well, technically it's tonight at midnight UTC, but who's splitting hairs?)

There's nothing too special planned for today, but we thought it'd be the perfect time to cut a slice of cake a release!

🎉 Notable changes

New generated code requires oapi-codegen/runtime v1.2.0+

As part of #​2256, github.com/oapi-codegen/runtime v1.2.0 is needed alongside github.com/oapi-codegen/oapi-codegen, for new generated code.

This is providing a more future-proofed means to bind parameters.

See the release notes for the runtime package, and #​2256 for more information.

oapi-codegen was part of the GitHub Secure Open Source Fund

oapi-codegen was one of the projects taking part in the third GitHub Secure Open Source Fund session.

We've written up more about what we've learned, and have some more things to share with you over the coming months about lessons we've learned and improvements we've taken that we can share.

We were pretty chuffed to be selected, and it's already helped improve our security posture as a project, which is also very important for the wider ecosystem!

go directive bump in next release

Long-time users will be aware that we work very hard to try and keep our requirement for Go source compatibility, through the go directive, especially as we recommend folks use oapi-codegen as a source-tracked dependency.

For more details about this, see our Support Model docs.

In the next minor release, we'll be setting our minimum go directive to Go 1.24 (End-of-Life on 2026-02-11), as it's required for a number of dependencies of ours to be updated any higher, and a change to the module import path for Speakeasy's OpenAPI Overlay library requires us fix this centrally for our users to be able to continue updating their libraries.

[!NOTE]
Nothing is changing as part of v2.6.0, this is a pre-announcement for v2.7.0.

Behind the scenes cleanup

There's also been some work behind-the-scenes to try and clean up outstanding issues (of which we know there are many!) that have been fixed, as well as Marcin's work on trying to do some more significant rework of the internals with help from Claude.

There's still, as ever, work to go with this - as we've mentioned before, sponsoring our work would be greatly appreciated, so we can continue to put in the work, considering this is a widely used and depended on project.
