Node.js default version description is contradictory: 24.x (system default in cached PATH) conflates two separate concepts and will mislead users.

💡 Details

The "system default" is the OS-installed Node.js version, while a "cached PATH" version is managed by the n version manager. These are mutually exclusive in the runner model.

The old text 20.x (system default) was accurate and clear. If 24.x is now the first cached version on PATH (effectively overriding system default), the correct wording is something like:

- **Default Version**: 24.x (first cached version on PATH via n)

Or if 24.x is genuinely now the system-installed default, drop the "cached PATH" qualifier.

Broken list structure — the - **Package Managers**: header line was deleted, leaving its child items (pip, pip3, pipx) as orphaned list entries with no parent context. Either restore the header or rewrite as a flat list.

Broken list structure in Python section: removing the - **Package Managers**: label leaves pip, pip3, and pipx as orphaned bullet points with no heading.

💡 Suggested fix

The diff removes the parent label but keeps the child items:

-  - **Package Managers**:
     - pip: 24.0
     - pip3: 24.0
     - pipx: 1.11.1

Either restore the - **Package Managers**: label, or promote the items to top-level bullets so they read as named properties of the Python section instead of dangling sub-list items.

GitHub CLI version appears to be a downgrade — this change updates gh from 2.96.0 → 2.93.0. Runner images ship progressively newer versions; a lower version in a newer image is unexpected and likely an analysis error. Please re-verify against the source documentation at the linked runner-images README.

@copilot please address this.

GitHub CLI version regresses from 2.96.0 to 2.93.0: a newer image shipping an older version of a tool is almost certainly a data-entry error.

💡 Details

The previous image 20260705.232.1 listed GitHub CLI at 2.96.0. This update to 20260720.247.2 lists it at 2.93.0. Runner images do not regress tool versions. The "Recent Changes" blurb also describes this as an "update", which is internally consistent but factually misleading.

Verify against the upstream source: https://github.com/actions/runner-images/blob/ubuntu24/20260720.247/images/ubuntu/Ubuntu2404-Readme.md

If the upstream README genuinely shows 2.93.0, explicitly call it out as a downgrade — not an update.
