v5.0.0
======

v5.0.0 is the first OpenMV Viewer release. OpenMV Viewer is a separate,
read-only build of OpenMV IDE for showing off a finished product built on an
OpenMV Cam: it streams the camera's live output and runs a script, but the
development tools are removed, so a customer or an end user can see what a
product does without the full development environment. It installs and runs
independently of OpenMV IDE.

Highlights
----------

- **A read-only telemetry viewer** — the frame buffer, serial terminal, and
  histogram work exactly as they do in OpenMV IDE, so you can watch what the
  camera captures and what its script prints live.
- **Runs a product's script** — Run and Stop work and run a script from disk,
  and the running script can be stopped when the viewer connects or
  disconnects, so a device is always in a known state.
- **Authoring tools removed** — the editor's development features, the machine
  vision authoring tools, the AI and model tools, and the developer settings
  are all stripped out, leaving a focused viewing application.
- **Installs on its own** — the viewer is branded and installed as *OpenMV
  Viewer*, with its own application name, settings, and identity, so it
  coexists with a full OpenMV IDE installation.

What's included
---------------

- **Live camera output** — the frame buffer viewer, the serial terminal, and
  the histogram, with the same controls as OpenMV IDE.
- **Run / Stop and stop-on-connect** — run the product's script from disk, and
  halt it when the viewer attaches or detaches.
- **File and Edit menus and Preferences** — kept so the viewer stays usable
  (open a file, adjust the interface), while the developer-only categories are
  hidden.
- **Firmware update and recovery** — the firmware manager, bootloader recovery,
  and loading a ROM file system onto the camera are kept, so the viewer can
  still recover or re-provision a device in the field.
- **Fiducial generators** — the AprilTag, DataMatrix, QR, and barcode
  generators are kept, since they are useful outside development too.

What's removed
--------------

- The script-authoring editor features, the machine vision tuning tools
  (threshold editor, keypoints editor, and the like), the AI and model-training
  tools, the model zoo and dataset editor, and the developer settings
  categories. Firmware-upgrade and onboarding prompts are suppressed so a demo
  never interrupts to change the device.

Platform and tool support
-------------------------

- **Qt Creator base:** 14.0.2 (shared with OpenMV IDE).
- **Availability:** Windows, macOS, and Linux, installed separately from OpenMV
  IDE.
