Install script (verifies checksums, installs oh to ~/.local/bin):

curl -fsSL https://updates.openheaders.io/install.sh | sh

Windows (PowerShell):

irm https://updates.openheaders.io/install.ps1 | iex

No Node.js required (npm install -g @openheaders/cli is the Node channel). macOS binaries are signed and notarized; the Windows oh is unsigned — SmartScreen warns on first run (More info → Run anyway). Script copies on this page: install-oh.sh · install-oh.ps1

What's New

Streams

• Grouped timelines — WebSocket messages can group by event and
  direction (Socket.IO events get their own axis), and gRPC streams
  group by message type and direction. Collapsed groups show the
  newest rows with a Show older toggle at the top edge, and you
  can pick how many rows each group keeps in Settings → Requests.
• Easier scanning — sticky group headers now clear the scrollbar,
  and stream rows highlight on hover.

Compose

• Wrap toggle — every editor pane gets its own Wrap control next
  to Beautify, with an indent cue on continuation lines. The new
  Editor dropdown in the toolbar also exposes the global display
  settings, applied live.
• Line endings — a new editor setting paints an end-of-line glyph
  on real newlines, so trailing characters and missing final newlines
  are visible at a glance.
• Bearer auth — the scheme prefix is now a fixed label instead of
  editable text, and masked token fields can be revealed while editing.

Response

• Status at a glance — the status chip is now a filled pill tinted
  by status class, and shows the canonical reason phrase when the
  server omits one.
• Tidier toolbar — Save Response moved into the overflow menu in
  the response panel and the gRPC/WebSocket result panes.

gRPC

• Spec switching — change the API spec straight from the method
  picker or the Service definition tab, and import definitions from
  either place.

Devices

• Safer peer execute — running requests on another device is now a
  two-tier opt-in: browsers on this machine are allowed by default,
  other devices start off. A refusal now says which host declined and
  jumps you to the matching opt-in row.

Activity

• Quieter unread cue — the activity tab now marks unseen entries
  with a small grey dot instead of a numeric badge, so background
  activity no longer reads as an alert.

Traffic

• Connection detail — captured desktop requests now record the
  dial: socket phases, negotiated protocol, local and remote
  endpoints, and request size.
