GitHub CLI 2.99.0 ڈاؤن لوڈ

Attach images and videos to issues and pull requests
The repeatable --attach flag uploads local images and videos and adds them to issue, pull request, or comment bodies. If a body already references the local path, gh replaces it with the uploaded URL; otherwise it appends the attachment:
# Attach files when creating or editing an issue
gh issue create --attach './repro.png#The error state'
gh issue edit 123 --attach ./walkthrough.mp4
# Attach files when creating or editing a pull request
gh pr create --attach ./before.png
gh pr edit 456 --attach ./after.png
# Attach files to comments
gh issue comment 123 --attach ./repro.png
gh pr comment 456 --attach ./result.mp4
Repeat the flag to attach multiple files in a single invocation. Attachments are available on GitHub.com and GitHub Enterprise Cloud.

Worktree support extended to gh issue develop
gh issue develop can now create a linked branch and check it out in a new Git worktree, leaving your current working copy unchanged:
# Create a linked branch for an issue and check it out in a worktree
gh issue develop 123 --checkout --worktree /path/to/wt-feature
