# blurb — Command-line tool to manage CPython Misc/NEWS.d entries.

License: permissive · Maintenance: active · Downloads: 103.7K/mo

## What it is and what it does

blurb is a specialized tool for CPython core development that solves the problem of merge conflicts in the Misc/NEWS file by splitting it into many individual entry files stored in Misc/NEWS.d. Each entry gets a unique filename based on timestamp and MD5 hash, ensuring no collisions even when multiple developers commit simultaneously. The tool provides subcommands to add new entries (which opens an editor for you to fill in a GitHub issue number and select a section), merge entries back into a single NEWS file, and manage releases.

The package is designed to be run from within a CPython repository and automatically uses the correct file paths. It supports Python 3.9 through 3.14 with no external runtime dependencies, making installation straightforward. For CPython contributors, the typical workflow is simply running `blurb add` (or just `blurb` with no arguments) to create a new entry; release managers use additional subcommands like `blurb merge` and `blurb release` to recombine entries and prepare releases.

Use it for:

- CPython contributor adding a NEWS entry for a commit without manually editing Misc/NEWS or resolving conflicts
- Release manager combining all pending entries into a single Misc/NEWS file during the release process
- Cherry-picking commits across CPython branches while automatically carrying the correct NEWS entry along
- Automating release notes generation by running blurb merge to reconstruct Misc/NEWS on demand

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

blurb is a command-line tool that manages CPython's release notes by splitting Misc/NEWS into individual entry files to eliminate merge conflicts, then recombining them on demand.

Yes, if you are a CPython core contributor or release manager. The tool directly solves the stated problem of Misc/NEWS merge conflicts and is actively maintained with no security vulnerabilities. For developers outside CPython core, it has no utility. Install via pip with no friction.

## Install

pip install blurb
uv add blurb
poetry add blurb

## Installing blurb

Before you install: Low install friction with no runtime dependencies. Actively maintained as of 2026-08-01 with recent release on 2025-01-15, supporting current Python versions 3.9 through 3.14.

License in practice: Permissive license allows broad use and modification without restriction.

Quickstart:

pip install blurb
blurb add
# Opens editor to add a new Misc/NEWS entry with GitHub issue number and section selection

Must be run inside a valid CPython Git repository; blurb automatically uses correct file paths relative to the repo root.

Verify before relying:

- Whether blurb is usable outside CPython development or only for CPython core contributors
- Performance characteristics when handling large numbers of entries in Misc/NEWS.d
