What changed

  • Built-in OAuth device flow for GitHub MCP server. devin mcp add github --url https://api.githubcopilot.com/mcp/ now authenticates via device flow (enter a code at github.com/login/device) without n…
  • /copy command to copy the last agent response to the system clipboard. Works over SSH connections and on Linux desktops.
  • Numbered options in select prompts can now be picked directly with the 1-9 keys instead of arrowing + Enter. The shortcut is shown as a digit prefix on each option in non-search prompts.
  • web_search tool for searching the web during agent sessions.
  • Cancelling a session now also stops running subagents instead of letting them continue in the background
  • Shell commands that redirect output to /dev/null (e.g. 2>/dev/null, >/dev/null, &>/dev/null) no longer prompt for write permission to /dev/null.
  • Edit tool previews now show correct file line numbers instead of always starting from 1.
  • Output token limit raised from 16k to match each model’s actual capacity (128k for Opus, 64k for Sonnet), preventing premature response truncation.
