+v1.0.0-beta
+===========
+
+v1.0.0-beta is the **initial (beta) release of the OpenMV firmware** — the
+first public build of the OpenMV Cam. It establishes the foundation everything
+since builds on: a **MicroPython** scripting runtime on the STM32F4 OpenMV
+Cam, a camera ``sensor`` API, an ``image`` machine-vision library, and the
+OpenMV IDE for live development. As the first release there is nothing to
+migrate from — this entry summarizes what the initial firmware shipped with.

+
+Highlights
+----------
+
+- **MicroPython on the OpenMV Cam** — run Python scripts on the camera over
+  USB with an interactive REPL and IDE debug interface.
+- **Camera capture** — the ``sensor`` module: configure pixel format /
+  resolution / frame rate and grab frames with ``snapshot()``.
+- **Machine vision** — the ``image`` library: color blob detection, drawing,
+  filters, template matching, Haar-cascade face detection, and keypoints.
+- **OpenMV IDE** — a desktop IDE with a live framebuffer viewer, code editor,
+  and in-IDE firmware update.
+- **Hardware** — the original OpenMV Cam (STM32F4) with OmniVision OV9650 /
+  OV2640 cameras, SD-card and WiFi-shield support.
+
+New features
+------------
+
+Scripting and modules:
+
+- A MicroPython runtime as the firmware base, with on-camera script execution
+  over a USB debug interface and an interactive REPL.
+- A ``sensor`` module — ``set_pixformat()`` / ``set_framesize()`` /
+  ``set_framerate()``, gain ceiling / brightness / contrast / gain controls,
+  ``reset()``, ``snapshot()``, and horizontal-mirror / vertical-flip — plus
+  sensor and resolution constants.
+- An ``image`` machine-vision module (imlib) exposing image objects (with the
+  Python buffer protocol) and the image-processing surface below.
+- A ``time`` / ``clock`` module for timing and FPS measurement.
+- Early peripheral modules — ``led`` (RGB LED), ``spi``, ``gpio`` (pin I/O
+  with external-interrupt registration), ``uart``, hardware ``rng``, a
+  systick timer, and ``file`` / ``select`` for the filesystem.
+- Networking via ``socket`` / ``wlan`` (CC3000 WiFi), an ``lcd`` display
+  driver, an ``mlx90620`` thermal-sensor module, and AVI/MJPEG video
+  recording.
+
+Image processing:
+
+- Camera frames captured into a dynamically allocated framebuffer.
+- Color blob detection (flood-fill) and LAB/XYZ-color-space thresholding
+  (with RGB↔LAB conversion tables).
+- Drawing primitives (line, string/font, circle), filters
+  (erode / dilate / median / invert / binary / threshold), image scaling
+  (bilinear), sub-image extraction, blit, and alpha blending.
+- Template matching (with template save/load), Viola-Jones Haar-cascade
+  face/object detection (loadable cascades + an OpenCV cascade converter), an
+  LBP cascade and eye detector, FAST / SURF / FREAK keypoint detection and
+  descriptor matching, integral images, and motion detection.
+- JPEG encoding (with quality control), PPM / PGM / PNG / raw image saving,
+  and AVI/MJPEG video encoding.
+
+IDE and tooling:
+
+- The OpenMV IDE desktop application — live framebuffer viewer with FPS, a
+  code editor (open / new / save / save-as, recent files, bundled Examples
+  menu), connect / reset / auto-connect, and configuration load/save.
+- In-IDE firmware update over DFU, a pure-Python ``pydfu`` utility, and a
+  force-into-bootloader USB command; the ``openmv.py`` host library/protocol;
+  a standalone framebuffer viewer and cascade tool; and Linux udev rules.
+
+Other changes and improvements
+------------------------------
+
+- Bundled example scripts: blob detection, face detection / tracking, SURF /
+  keypoints, template matching, LCD, framebuffer viewer, blit, MJPEG
+  streamer, AVI recording, echo server, FPS, and JPEG / image-write demos.
+
+Hardware and board support
+--------------------------
+
+- **OpenMV Cam** — STM32F4xx (STM32F407 / F429) across the early hardware
+  revisions, with CMSIS + STM32 peripheral/Cube HAL and CMSIS-DSP.
+- **Cameras** — OmniVision OV9650 and OV2640 (SCCB/I2C, regulator control)
+  via a sensor HAL, plus the MLX90620 thermal IR sensor; resolutions from
+  QQCIF/QCIF up to SVGA/UXGA at up to 30 FPS.
+- **Storage / connectivity** — SD card (SPI and SDIO) with FatFS, an internal
+  flash filesystem, SDRAM (framebuffer in SDRAM), USB OTG FS (debug + DFU),
+  CC3000 WiFi (WiFi / BLE shields), an IR LED, and soft/hardware I2C and
+  DMA-driven SPI.
+
+Breaking API changes
+--------------------
+
+None. v1.0.0-beta is the **initial (beta) release of the OpenMV firmware** —
+there is no prior release to break compatibility with. Subsequent releases
+document their breaking changes against their predecessor; see the rest of
+:ref:`the changelog <changelog>`.
