What's New

Version control

• Git tool window — a workspace bound to a git repository gains a
  full Version Control tool window. The log pane draws the commit
  graph with ref labels for branches and tags, per-pane toolbars with
  filter chips and view options, a sticky branch scope, and a details
  pane for the selected commit.
• Branches rail — an activity-bar rail lists local and remote
  branches with checkout, create, and compare verbs; comparing two
  refs opens as its own tab.
• Commit window — a changes tree with tri-state checkboxes,
  keyboard navigation, and per-row context menus stages exactly what
  you pick; commit and amend run from the tree, and the working diff
  sits beside it. Single-chain directories compress to one row, the
  IDE way.
• Ignore management — Add to .gitignore and Stop Ignoring live on
  the tree's context menus, and ignored rows say which ignore file
  and pattern claimed them.
• Console tab — every git command the app runs is visible in a
  console tab, so nothing happens behind your back.

Traffic

• Capture sessions — the Traffic monitor can record what it
  observes into sealed, encrypted session archives: auto-named at
  seal, deduplicated storage for bodies, a retention budget with
  garbage collection, and recovery of interrupted recordings on next
  launch.
• Replay — a sealed session opens back up in the same viewer the
  live Traffic monitor uses — rows, timings, and bodies resolve from
  the archive even after the browser tab is long gone.
• Sessions in the sidebar — recorded sessions live in a SESSIONS
  section of the sources rail: search, sort, folders, rename and
  organize verbs, and open-on-click replay.
• Redesigned monitor — the Traffic monitor moves into the dock as
  a tool window with a per-source tab row, a sources rail, and a
  start/stop capture control in the header.
• Clear names — the wire vocabulary is now Traffic Interception,
  the system proxy settings group reads Proxy · System, and Install
  CA takes you straight to the trust pane.

AI agents

• Observe traffic over MCP — with an explicit workspace grant, an
  AI agent connected to the app's MCP server can observe captured
  traffic: list sources and requests, pull failures with their
  bodies, diff two requests, wait on traffic matching a predicate,
  and read redirect chains.
• Redaction first — sensitive fields are redacted in everything
  an agent reads, and redacted markers say so honestly; turning a
  captured request into a rule forces a draft whenever redacted
  fields are involved.
• Session tools — agents can list and read sealed capture
  sessions; raw unredacted reads sit behind their own grant, off by
  default, and every raw read is stamped in the observe feed.

Workbench

• Compact sidebar — denser rows, hover-gated controls, one global
  focus tint, and slimmer dividers across the sidebar trees.
• Speed-search — the sidebar gains an on-demand filter/search
  mode; filtering prunes empty folders and highlights no-match state.
• Tool windows keep their state — switching dock tabs no longer
  resets a tool window's scroll and selection; bodies stay mounted
  and pick up where you left them.
• Bottom panel splits — the bottom panel can hold two tool
  windows at once, side by side or stacked. Pick the arrangement from
  the merged Bottom Panel Layout menu or the panel toolbar, or drag a
  tab onto a drop zone to split in place.
• Reveal means focus — actions that reveal a tool window now
  focus it too, landing on its natural input so the keyboard follows
  your intent.
