- Choose the best model for each task. Switch models mid-conversation, and Copilot keeps your choice for the rest of the thread. In Slack, you can also set channel defaults.
- Avoid duplicate issues since Copilot now checks for similar existing issues before creating a new one.
- Follow longer-running tasks more easily with clearer implementation-plan status, better recovery from interrupted or stale replies, and more predictable reconnection when a conversation goes idle.
- Give Copilot more context in Slack by sharing supported files, attachments, and message links. Learn more about GitHub Copilot public previews in Slack and Teams . GitHub Copilot in JetBrains
- Assisted approvals, now in public preview for Copilot agent sessions, automatically approve low-risk tool calls while prompting you for higher-risk actions.
- Edit an earlier message to redirect an agent session and Copilot rewinds both the conversation and file changes before sending the replacement request.
- Shared organization and enterprise skills, along with organization-managed custom instructions, now work in local and Copilot agent sessions. Learn more in the full Copilot in JetBrains changelog . GitHub Copilot in VS Code 1.139 release
- Run agents in Dev Containers on SSH, Tunnel, and WSL hosts, using your remote project's tools and dependencies. Support is rolling out gradually.
- Keep busy session lists organized with Compact View, filters to hide empty groups, and the ability to rename sessions and chats directly in the list.
- Choose between separate chat tabs or a single active-chat view within a session, without losing your conversations. This layout option is now in preview. Explore everything that's new in the full release notes . Table of Contents
