• stop hardcoding protoc-gen-js plugin version in download script. This fixes an issue where @protocolbuffers/protoc-gen-js only downloads v4.0.0, which lacks support for editions 2024

Full Changelog: v4.0.1...v4.0.2

EDIT: Feb. 27, 2026: macos and windows releases were mistakenly double-zipped, causing further problems for the @protocolbuffers/protoc-gen-js's download script. Re-uploading the inner zip files to fix.

Full Changelog: v4.0.2-rc4...v4.0.2-rc5

v4.0.2-rc4

Bump version to 4.0.2-rc4 for testing BCR workflow

v4.0.2-rc3

Add placeholder google-protobuf.js file to fix missing input

Release workflow currently errors out with `//:dist_files: missing
input file '//:google-protobuf.js'` because we normally only generate
it as part of the cross-compiled binary and npm releases. However,
this seems to be causing problems for the BCR release process because
the build target is broken without it.

This change just adds a placeholder file to smooth things over.

Bump version to 4.0.2-rc2 for testing BCR workflow

v4.0.2-rc2

Bump version to v4.0.2-rc2 or testing BCR workflow

v4.0.2-rc1

Bump version to 4.0.2-rc1 for testing BCR workflow (#265)

The BCR publishing workflow requires a tag, and we can't use v4.0.1
since it didn't yet contain the actions. We will hold off doing an
actual plugin release to npm until BCR is settled.

v4.0.1

• Add support for protobuf edition 2024
• Add --version argument to protoc-gen-js binary for easier version checking. E.g. running ./protoc-gen-js will yield 4.0.1.

Update 2026-09-10:

We originally failed to publish a *-win64.zip package. However, the *-win32.zip is actually a 64-bit binary (file yields protoc-gen-js.exe: PE32+ executable for MS Windows 6.00 (console), x86-64, 6 sections). Re-uploading a freshly downloaded *-win32.zip binary renamed to win64.

v4.0.0

What's Changed

• Backport: binary proto serialization/deserialization changes and enable protobuf Editions 2023 (breaking change)
• Backport: Fix JSPB binary utf8 decoding and validate by default (breaking change)
• Do not ignore descriptor extensions
• Limit global resolution to globalThis by (breaking change)
