Antigravity 2.28.0

[Improvements] Antigravity now has a built-in browser. Web pages open in a browser tab in the side panel, and the panel widens when a page opens so sites are less likely to switch to their narrow mobile layout.

[Improvements] You can now attach files of any type, such as videos, design files, or programs, up to 20 MB. Files that used to be rejected as an unsupported format are attached as files, and the agent reads them from where they are saved.

[Improvements] Links you open from a conversation open in the built-in browser by default. To use your external browser instead, change Open Links In under Settings > General, or right-click a link to pick either browser or copy the link.

[Improvements] PDF files now open in a built-in PDF viewer, both in the file viewer and when an artifact is a PDF, so you can read them without leaving Antigravity.

[Improvements] New status icons show when the agent is working, running a background command, or waiting on your answer, and a conversation keeps showing as working while its subagents run. The conversation hover card also shows states such as Action required, Working, and Unread.

[Improvements] Hooks you define now receive the current user message, so a hook can check a prompt before the agent acts on it.

[Improvements] Improved performance while responses stream in and when switching between conversations.

[Improvements] The project picker opens and responds much faster when you have hundreds of projects.

[Improvements] The built-in browser's address bar shows whether your connection to a site is secure, with its certificate details, or a Not secure warning. Its tabs also keep each site's icon as you move between pages.

[Improvements] Diffs now highlight the exact words and characters that changed within a line, including in edits that span several lines, and added text is easier to see in dark mode.

[Improvements] You can now reopen side panel tabs you closed, at their previous position and scroll point, with Cmd+Shift+T on macOS or Ctrl+Shift+T on Windows and Linux.

[Improvements] You can now move the open conversation up or down in the sidebar with Alt+Shift+Up and Alt+Shift+Down (Option+Shift on macOS), including into Pinned and other sections.

[Improvements] Selecting a quote in a message now scrolls the conversation to the quoted text and briefly highlights it.

[Improvements] Long commands in the background command view are now syntax highlighted and collapsed to three lines, with a toggle to expand them when they overflow and a Copy button.

[Improvements] Screen readers now announce what the agent is doing while it works, including how long it has been thinking, each response, and when a turn is canceled or fails.

[Improvements] In windows narrower than 1024 pixels, the sidebar and side panel no longer open side by side. Opening the side panel hides the sidebar, and the sidebar button closes the side panel, so the conversation keeps its room.

[Improvements] The Wide conversation width setting is now wider, at 960 pixels, so it makes better use of large screens.

[Improvements] Web addresses in notifications are now links you can open, such as the appeal form link in an account error message.

[Improvements] The sidebar and side panel buttons now appear filled while their panel is open, so you can tell at a glance which panels are showing.

[Fixes] Fixed an issue where a conversation could switch to a different model after Antigravity restarted or reconnected.

[Fixes] Fixed an issue where some enterprise accounts on macOS and Windows were not kept signed in after a restart, because the saved sign-in was too large for the system keychain.

[Fixes] Fixed an issue where subagents asked again about a command or website you had already approved with Always allow or for the conversation, and where choosing to always allow something when not in a project was not saved.

[Fixes] Fixed an issue where the built-in browser showed an error screen instead of pages that returned an error code but still had content, such as security checks and custom 404 pages, or kept showing an old error after you switched tabs.

[Fixes] Fixed an issue where a failed plugin install, removal, or toggle on the Marketplace tab showed no error there, and the error appeared later on another plugin's page.

[Fixes] Fixed an issue where installing a plugin failed with no way forward when its folder held a broken copy, such as one left by a failed update. The install dialog now offers Replace.

[Fixes] Fixed an issue where some plugin MCP servers whose command starts with ./ failed to start when they set a working folder other than the plugin's own folder.

[Fixes] Fixed an issue where the conversation jumped to the bottom when you quoted an earlier passage or when a queued message was sent, so you lost your place.

[Fixes] Fixed an issue where mentions and quotes in a queued follow-up message showed as raw text instead of pills.

[Fixes] Fixed an issue where a turn that was still running could collapse its latest Worked for section and hide the Working indicator.

[Fixes] Fixed an issue where bold, italic, and strikethrough text next to punctuation in Chinese, Japanese, or Korean showed the raw markdown markers.

[Fixes] Fixed an issue where pasted GIF images were rejected by models that do not accept GIFs.

[Fixes] Fixed an issue where holding Backspace to clear a search in the command palette also removed its category, such as Files or Conversations.

[Fixes] Fixed an issue where the media viewer's copy, download, and close buttons and zoom control looked like dark gray blobs in light mode.

[Fixes] Fixed an issue where the send button changed size and shifted when the message box finished loading.
