on GitHub

Weekly Pre-Release Build of Altair

This is a pre-release version for testing purposes.

Build Information

Version: 6.2.0.dev20260427
Tag: weekly-20260427-e8ce2f2
Previous Weekly Tag: weekly-20260420-e093674

Installation

From PyPI (recommended)

Install the latest weekly build directly from PyPI:

pip install altair==6.2.0.dev20260427
# or
uv pip install altair==6.2.0.dev20260427

Note: Weekly builds publish timestamped development versions (for example 6.2.0.dev20260427) to PyPI. When you pin that exact version, pip installs the dev build automatically, without the need for a --pre flag.

From GitHub Repository (direct install)

Install directly from the tagged commit without downloading the wheel:

Command line (pip or uv):

pip install git+https://github.com/vega/altair.git@weekly-20260427-e8ce2f2
# or
uv pip install git+https://github.com/vega/altair.git@weekly-20260427-e8ce2f2

Note: Installing directly from the weekly-... tag will surface the base development version (without the timestamp suffix) because the version file edits are not committed.

Add to pyproject.toml (pip/uv):

[project]
dependencies = [
    "altair @ git+https://github.com/vega/altair.git@weekly-20260427-e8ce2f2",
]

Add to pixi.toml (pixi):

[pypi-dependencies]
altair = { git = "https://github.com/vega/altair.git", rev = "weekly-20260427-e8ce2f2" }

From GitHub Release (manual download)

Download the wheel or sdist from the release assets and install, for example:

pip install ./altair-6.2.0.dev20260427-py3-none-any.whl
