GitHub Copilot's Slack and Teams bot gains file and image context
The bot also switches models mid-conversation and files linked issues from a thread; separately, VS Code 1.139 runs agents in remote dev containers.

Copilot's chat bot finally reads your files and threads
In Slack and Teams, Copilot now ingests attachments, inline images, message links and thread history, and checks for similar issues before opening a new one — so a bug pasted into a channel becomes a scoped, linked GitHub issue that traces back to the conversation. You can switch the model for the next message and keep that choice for the thread, and Slack users can set default repos and owners. It's public preview on Copilot Business and Enterprise, billed against existing entitlements.
VS Code 1.139 runs agents inside remote dev containers
Agent sessions can now run in Dev Containers over SSH, Tunnel and WSL, so an agent uses your project's real toolchain instead of you rebuilding it on the host. Initial session listing is about 12x faster (1.3s to 0.1s across 645 sessions), and chats add Multiple/Single view modes plus double-click renaming.
