Upgrade Antigravity to 1.2.17 and run Windows Python, Git, and npm without administrator rights

Antigravity 1.2.17 lets the Windows command sandbox run Python, Git, and npm without administrator rights, adds Esc-dismissible announcement cards for model launches and deprecations, and stops TIFF-to-PNG mis-conversion plus emoji/Hindi markdown table drift over SSH and tmux.

Why this loop

1.2.17 changes three daily habits. On Windows, sandboxed commands no longer need administrator rights and Python, Git, and npm work inside the sandbox out of the box, so stop elevating the CLI or turning the sandbox off for those tools. Service notices now appear as cards above the prompt, one at a time, newest first; Esc on an empty prompt permanently dismisses the current card and shows the next, while sending a message only hides it for the rest of the session—use Esc after reading deprecation or launch notices so they do not return. The agent also reports .tiff files with the correct type instead of silently converting them to PNG, and markdown table columns no longer drift when a cell has emoji such as ⚠️ or 👍🏽 or combining scripts such as Hindi over SSH or tmux, so drop workarounds for those cases.

Proposed actions

  1. Upgrade Google Antigravity CLI to 1.2.17 from https://github.com/google-antigravity/antigravity-cli/releases/tag/1.2.17 before the next session.
  2. On Windows, instruct the agent: Run Python, Git, and npm inside the Antigravity command sandbox and do not request administrator rights; 1.2.17 no longer needs elevation for those tools.
  3. When an announcement card appears above the prompt, press Esc on an empty prompt to dismiss that card permanently (newest first) and show the next model-launch or deprecation notice; send a message only if you want it hidden for this session.
  4. Tell the agent: Open .tiff files in place and report them as TIFF; do not convert them to PNG.
  5. In SSH or tmux sessions, keep markdown tables that include ⚠️, 👍🏽, or Hindi combining characters; columns should stay aligned without extra padding.

Verified excerpt — the source's own words
  • Added announcement cards above the prompt for model launches, deprecations, and other service notices. Cards appear one at a time, newest first; press Esc on an empty prompt to dismiss the current card permanently and show the next one, and sending a message hides the card for the rest of the session.
  • Improved the Windows command sandbox so sandboxed commands no longer need administrator rights, and common tools such as Python, Git, and npm work inside the sandbox out of the box.
  • Fixed markdown table columns drifting out of alignment when a cell contains emoji such as ⚠️ or 👍🏽 or scripts with combining characters such as Hindi, which affected every session over SSH or inside tmux.
  • Fixed .tiff images being reported with the wrong file type and silently converted to PNG when the agent viewed them.
