I ran it against a branch with the latest Node.js 26.7.0 removed, and ./update.sh 26 added it correctly.

Did a quick test with curl -sSL --compressed "https://nodejs.org/dist/index.json" | jq -r '[.[] | select(.version | startswith("v24."))] | first | .version | ltrimstr("v")'.
Did something similar with the JS rewrite branches

I don't have write access here, so will leave this with y'all to land 🙏

[MikeMcC399]

I tested it also in my fork, both on the current state and rewinding to Node.js 26.6.0 and it worked fine.

Thank you for your support @MattIPv4 👍🏻

I've added two PRs due to the additional requirement to have jq installed. the additional error messages if jq wasn't already installed.

#2599
#2600

This isn't an issue in GitHub runners. It just needs an additional step for contributors if they don't already have jq installed.

The error message without jq installed is quite messy:

Ah, ty! I had assumed jq was safe to use as it was already used elsewhere in the script.

Ah, ty! I had assumed jq was safe to use as it was already used elsewhere in the script.

I've put the text right in the related PRs. My assumption that jq was new was incorrect. The additional usage just made the error messages a lot more intensive!
