New versions are released through GitHub, so the reference page is the [GitHub Releases](https://github.com/natario1/CameraView/releases) page.

Starting from 2.4.0, you can now [support development](https://github.com/sponsors/natario1) through the GitHub Sponsors program. 
Companies can share a tiny part of their revenue and get private support hours in return. Thanks!

- [*Camera1*] New: support for `previewFrameRate` for Camera1 ([#661][661])
- [*Camera2*] Fix: fix crashes when taking snapshots very early ([#651][651])
- [*Preview*] Fix: Fixed preview being upside-down for 180 degrees flips ([#651][651])
- Fix: other bug fixes ([#651][651])

https://github.com/natario1/CameraView/compare/v2.3.1...v2.4.0

### v2.3.1

- [*Video*] Improvement: better timing for `onVideoRecordingStart()` thanks to [@agrawalsuneet][agrawalsuneet] ([#632][632])
- [*Video, Camera1*] Fix: fixed video errors when starting on specific devices ([#617][617])
- [*Video*] Fix: fixed crash when closing the app during video snapshots ([#630][630])
- [*Preview*] Fix: fixed crash when using `GL_SURFACE` ([#630][630])

https://github.com/natario1/CameraView/compare/v2.3.0...v2.3.1

## v2.3.0

- [*Camera2, Metering*] New: `startAutoFocus` is much more powerful and does 3A metering (AF, AE, AWB) ([#574][574])
- [*Camera2, Metering*] New: `setPictureMetering(boolean)` decides whether to do metering before `takePicture()`. Defaults to true to improve quality. ([#580][580])
- [*Camera2, Metering*] New: `setPictureSnapshotMetering(boolean)` decides whether to do metering before `takePictureSnapshot()`. Defaults to false to improve latency. However, you can set this to true to greatly improve the snapshot quality, for example to support `Flash`. ([#580][580])
- [*Camera2, Metering*] New: metering extended to many more cameras, which can now use `startAutoFocus` or the focus gesture ([#574][574])
- [*Camera2, Metering*] Improvement: `onAutoFocusEnd` is now guaranteed to be called ([#574][574])
- [*Camera2, Metering*] Improvement: taking picture does not invalidate the previous focus ([#574][574])
- [*Camera2, Metering*] Improvement: better metering when zoomed in ([#574][574])
- [*Real time filters*] **Breaking change**: `Filter` interface signatures now accept timestamps for animations ([#588][588])
- [*Overlays*] New: you can now use `addView()` and `removeView()` to add or remove overlays at runtime (see docs) ([#588][588])
- [*Video*] Improvement: better encoder selection ([#588][588])
- Fix: fixed various bugs and improved stability ([#588][588])

https://github.com/natario1/CameraView/compare/v2.2.0...v2.3.0

## v2.2.0

https://github.com/natario1/CameraView/compare/v2.0.0-rc1...v2.0.0-rc2

## v2.0.0-rc1

This is likely to be the last release before v2.0.0.

- New: support for watermarks and animated overlays ([docs](../docs/watermarks-and-overlays.html)), thanks to [@RAN3000][RAN3000] ([#502][502], [#421][421])

- Improvement: improved Camera2 stability and various bugs fixed (e.g. [#501][501])
- Improvement: improved video snapshots speed, quality and stability ([#506][506])

https://github.com/natario1/CameraView/compare/v2.0.0-beta06...v2.0.0-rc1

### v2.0.0-beta06

- New: Full featured Camera2 integration! Use `cameraExperimental="true"` and `cameraEngine="camera2"` to test this out. ([#490][490])
- Improvement: we now choose a video recording profile that is compatible with the chosen size. Should fix some video recording issues. ([#477][477])
- Improvement: most internals are now open to be accessed by subclassing. Feel free to open PRs with more protected methods to be overriden. ([#494][494])
- **Breaking change**: some public classes have been moved to different packages. See [table here](../extra/v1-migration-guide.html#repackaging). ([#482][482])
- **Breaking change**: the listener methods `onFocusStart` and `onFocusEnd` are now called `onAutoFocusStart` and `onAutoFocusEnd`. ([#484][484])
- **Breaking change**: the gesture actions `focus` and `focusWithMarker` have been removed and replaced by `autoFocus`, which shows no marker. ([#484][484])
- New: new API called `setAutoFocusMarker()` lets you choose your own marker. ([#484][484])

If you were using `focus`, just switch to `autoFocus`.

If you were using `focusWithMarker`, you can [add back the old marker](../docs/metering.html#touch-metering-markers).

https://github.com/natario1/CameraView/compare/v2.0.0-beta05...v2.0.0-beta06

### v2.0.0-beta05

- Fixed `FrameProcessor` freeze and release behavior, was broken ([#431][431])
- New: new api `setAutoFocusResetDelay` to control the delay to reset the focus after autofocus was performed, thanks to [@cneuwirt][cneuwirt] ([#435][435])
- Faster camera preview on layout changes ([#403][403])
- A few bug fixes ([#471][471])

https://github.com/natario1/CameraView/compare/v2.0.0-beta04...v2.0.0-beta05

### v2.0.0-beta04

- Renames setPreviewSize to setPreviewStreamSize (previewSize suggests it is related to the view size but it's not) ([#393][393])
- Added new APIs `setSnapshotMaxWidth` and `setSnapshotMaxHeight` ([#393][393]). You can now have a good looking preview but still take low-res snapshots using these snapshot constraints. Before this, the two sizes were coupled.

https://github.com/natario1/CameraView/compare/v2.0.0-beta03...v2.0.0-beta04

### v2.0.0-beta03

- Fixed a few bugs ([#392][392])

https://github.com/natario1/CameraView/compare/v2.0.0-beta02...v2.0.0-beta03

### v2.0.0-beta02

- Fixed important bugs ([#356][356])
- Picture snapshots are now flipped when front camera is used ([#360][360])
- Added `PictureResult.getFacing()` and `VideoResult.getFacing()` ([#360][360])

https://github.com/natario1/CameraView/compare/v2.0.0-beta01...v2.0.0-beta02

## v2.0.0-beta01

This is the first beta release. For changes with respect to v1, please take a look at the [migration guide](../extra/v1-migration-guide.html).

### v1.6.1

This is the last release before v2.

- Fixed: crash when using TextureView in API 28, thanks to [@Keyrillanskiy][Keyrillanskiy] ([#297][297])
- Fixed: restore Frame Processor callbacks after taking videos, thanks to [@stefanJi][stefanJi] ([#344][344])
- Enhancement: when horizontal, camera now uses the last available orientation, thanks to [@aartikov][aartikov] ([#290][290])
- Changed: we now swallow exceptions during autoFocus that were happening unpredictably on some devices, thanks to [@mahdi-ninja][mahdi-ninja] ([#332][332])

https://github.com/natario1/CameraView/compare/v1.6.0...v1.6.1

## v1.6.0

- Lifecycle support. Use `setLifecycleOwner` instead of calling start, stop and destroy ([#265][265])
- Enhancement: provide synchronous version of CameraUtils.decodeBitmap thanks to [@athornz][athornz] ([#224][224])
- Enhancement: prevent possible context leak thanks to [@MatFl][MatFl] ([#245][245])
- Bug: fix crash when using default VideoCodec thanks to [@Namazed][Namazed] ([#264][264])
- Enhancement: CameraException.getReason() gives some insight about the error ([#265][265])
- Enhancement: Common crashes are now being posted to the error callback instead of crashing the app ([#265][265])

https://github.com/natario1/CameraView/compare/v1.5.1...v1.6.0

### v1.5.1

- Bug: byte array length for Frames was incorrect thanks to [@ssakhavi][ssakhavi] ([#205][205])
- Bug: gestures were crashing in some conditions ([#222][222])
- Bug: import correctly the ExifInterface library ([#222][222])
- Updated dependencies thanks to [@caleb-allen][caleb-allen] ([#190][190])

https://github.com/natario1/CameraView/compare/v1.5.0...v1.5.1

## v1.5.0

- New: set encoder for video recordings with `cameraVideoCodec` ([#174][174])
- New: set max duration for videos with `cameraVideoMaxDuration` ([#172][172])
- Enhancement: reduced lag with continuous gestures (ev, zoom) ([#170][170])
- Bug: tap to focus was crashing on some devices ([#167][167])
- Bug: capturePicture was breaking if followed by another event soon after ([#173][173])

https://github.com/natario1/CameraView/compare/v1.4.2...v1.5.0

### v1.4.2

- Add prefix to XML resources so they don't collide, thanks to [@RocketRider][RocketRider] ([#162][162])
- Add `videoMaxSize` API and XML attribute, to set max size video in bytes, thanks to [@chaitanyaraghav][chaitanyaraghav] ([#104][104])
- Improved the preview size selection, thanks to [@YeungKC][YeungKC] ([#133][133])
- Improved the playSounds attribute, was playing incorrectly, thanks to [@xp-vit][xp-vit] ([#143][143])

https://github.com/natario1/CameraView/compare/v1.4.1...v1.4.2

### v1.4.1

- Fixed a bug that would flip the front camera preview on some devices ([#112][112])
- Two new `CameraOptions` APIs: `o.getSupportedPictureSizes()` and `o.getSupportedPictureAspectRatios()` ([#101][101])
- Most controls (video quality, hdr, grid, session type, audio, white balance, flash, facing) now inherit
  from a base `Control` class ([#105][105]). This let us add new APIs:

  - `CameraView.set(Control)`: sets the control to the given value, e.g. `set(Flash.AUTO)`
  - `CameraOptions.supports(Control)`: returns true if the control is supported
  - `CameraOptions.getSupportedControls(Class<? extends Control>)`: returns list of supported controls of a given kind

https://github.com/natario1/CameraView/compare/v1.4.0...v1.4.1

## v1.4.0

- CameraView is now completely thread-safe. All actions are asynchronous. ([#97][97])
  This has some breaking drawbacks. Specifically, the `get` methods (e.g., `getWhiteBalance`) might
  not return the correct value while it is being changed. So don't trust them right after you have changed the value.
  Instead, always check the `CameraOptions` to see if the value you want is supported.
- Added error handling ([#97][97]) in `CameraListener.onCameraError(CameraException)`.
  At the moment, all exceptions there are unrecoverable. When the method is called, the camera is showing
  a black preview. This is a good moment to show an error dialog to the user.
  You can also try to `start()` again but that is not guaranteed to work.
- Long requested ability to set the picture output size ([#99][99]). Can be done through
  `CameraView.setPictureSize()` or through new XML attributes starting with `cameraPictureSize`.
  Please refer to docs about it.
- Deprecated `toggleFacing`. It was unreliable and will be removed.
- Deprecated `getCaptureSize`. Use `getPictureSize` instead.
- Fixed bugs.
