Nearest release: v2.1.322, published 15 hours before upstream edited the page. Shown because the two are within 24 hours of each other. Nothing here says the release caused the edit.

Upstream edited this page at 10 Nov 2026 17:26 UTC, give or take a minute or two: the time comes from Anthropic’s own sitemap rather than from a commit. This site recorded the change at 10 Nov 2026 17:37 UTC.

59Claude Science itself does not require GitHub; the package manager ships inside the app. The GitHub domains are used only when a package Claude installs is published as a GitHub release or a member imports a skill from a GitHub repository, and blocking them fails only those operations.
59Claude Science itself does not require GitHub; the package manager ships inside the app. The GitHub domains are used when a package Claude installs is published as a GitHub release, when a member imports a skill from a GitHub repository, and when code Claude runs reaches GitHub, for example with `git clone`, `git fetch`, or `git push`. If your firewall blocks them, those operations fail.

6161When you configure a conda channel mirror, Claude Science removes only the conda hosts (`conda.anaconda.org`, `repo.anaconda.com`, `anaconda.org`, `*.anaconda.org`) from the allowlist, and a Python index mirror removes only `pypi.org`, `*.pypi.org`, and `files.pythonhosted.org`. The `*.conda.io`, CRAN and Bioconductor, npm, and GitHub rows stay. A removed host is reachable again if a member re-adds it under **Settings** > **Network** or an administrator lists it in `[sandbox.network] allowed_domains`, which takes precedence over the removal. Environment builds contact the mirror host directly from the workstation, not through the outbound proxy, so it must be reachable directly (over your VPN or internal network if the mirror is internal, HTTPS on TCP 443 or 8443). A proxy allowlist entry alone does not make the mirror reachable for builds, and build-time mirror traffic will not appear in your proxy logs. See [Point package installs at an internal mirror](https://claude.com/docs/claude-science/corporate-networks.md#point-package-installs-at-an-internal-mirror).
