Apache Arrow Go 18.0.0 Release

Published 23 Oct 2024
By The Apache Arrow PMC (pmc)

The Apache Arrow team is pleased to announce the v18.0.0 release of Apache Arrow Go. This release covers 35 resolved issues from 11 contributors.

Release Highlights

Move to new Repository

The Apache Arrow Go implementation has been shifted out of the Arrow monorepo and to its own repository now located at https://github.com/apache/arrow-go. This will enable fewer major version releases and facilitate more minor version/patch releases instead as it will detach the version number from the Arrow C++ and other implementations in the monorepo.

Current users of Arrow Go will want to carefully note the breaking change to module paths this move causes. To upgrade to Arrow Go v18.0.0, ensure you properly update all relevant module paths in your go.mod, replacing all instances of github.com/apache/arrow/go/ with github.com/apache/arrow-go.

Existing Go related issues have been moved to the new repository and please file any new issues on the new repository instead of the Arrow monorepo.

Go Version

With this release, the minimum Go version is now 1.22.
