4.2.0 (2026-07-31)

Features - 4.2.0

• Publish cp315t wheels, so a free-threaded 3.15 installs a wheel instead of compiling the Rust extension. (:issue:644)

Bug fixes - 4.2.0

• Publish Linux aarch64 wheels. 4.1.0 shipped none, so pip and uv fell back to the source distribution on ARM64 hosts, where building the Rust extension needs a local cargo and C toolchain. (:issue:640)
• Build from source on a free-threaded interpreter. The package asked for the limited API unconditionally and meson-python refuses to pair it with a free-threaded CPython, so the source build stopped before it started. (:issue:643)

Packaging updates - 4.2.0

• Take the released version from the git tag rather than from a file in the tree, so a release can no longer ship artifacts labeled with the previous version. 4.1.1 and 4.1.2 were tagged that way and reached no index. (:issue:647)

Releases up to 4.1.0 are recorded on the GitHub releases page <https://github.com/tox-dev/pipdeptree/releases>_.
