13.0.2

Camera Compatibility

• Added support for the OM System OM-1 Mark II.

• When connected via USB, the Canon EOS 1300D no longer has the CBLCameraSupportedFunctionalityLimitedRemoteControlWithoutLiveView functionality flag, and has the full range of shutter control. Behaviour when connected via WiFi is unchanged.

Bug Fixes

• Fixed a bug that'd cause KVO observations to not fire for the currentCommandCategories property with Olympus/OMS cameras.

• Improved the reliability of live view on the Canon EOS 1300D, particularly when switching between photo and video modes. Live view will be terminated if it's active when such a mode change occurs, but the camera will no longer go into an undefined state.

13.0.1

Camera Compatibility

• Fixed incorrect parsing of Nikon "extended" shutter speed values (longer than 90 seconds). [CORE-671]

• Added localised string values for Nikon U60 and U120 drive modes. [CORE-672]

13.0.0

Support for Mac Catalyst

CascableCore now supports the Mac Catalyst platform on both Intel and Apple Silicon. The minimum required deployment target is Mac Catalyst 15.0, which shipped with macOS 12.

Support For Encrypted Connections to Sony Cameras

Sony have added an encrypted network connection option, on by default, to its newest cameras. They're also backdeploying this feature to some existing cameras, such as the α7 IV, via firmware updates. We're pleased to announce that CascableCore now fully supports these encrypted connections.

Due to the need to collect a username and password to connect to these cameras, the camera connection API has breaking changes. See the documentation and demo projects for examples on the new camera connection API.

Improved Live View Zoom

We've revamped live view zoom, which has introduced breaking changes to this API.

• The CBLCameraSupportedFunctionalityZoomableLiveView functionality flag is now deprecated, and the -setLiveViewZoomLevel:completionCallback: method has been removed.

• A new property, CBLPropertyIdentifierLiveViewZoomLevel, has been added in replacement. The property can expose multiple zoom levels, and values conform to id <CBLLiveViewZoomLevelPropertyValue> allowing you to target specific zoom levels, make sure the camera is or isn't zoomed in, etc.

• Added a new functionality flag, CBLCameraSupportedFunctionalityPannableLiveView, which signals whether a camera can pan around a zoomed-in live view. If available, the new method -setLiveViewZoomCenterPoint:completionCallback: can be used to pan live view around.

Camera Compatibility

• Added support for the Sony α7R V, α7C R, α7C II, and α6700. [CORE-564]

• Added support the Nikon Z f. [CORE-636]

• Added touch AF, focus geometry, and live view zoom to newer Sony cameras that support these features. [CORE-565, CORE-566]

• Improved live view zoom support for Nikon cameras. [CORE-50]

• For newer Sony cameras, the -currentCommandCategories property now more accurately represents the camera's state, and calling -setCurrentCommandCategories:… will now manipulate the exposure mode property in order to get the camera into the desired state. [CORE-594]

Bug Fixes

• Implemented a number of improvements in an attempt to track down reports of truncated file transfers from Canon EOS 5D Mark IV cameras. [CORE-606]

• The rating and isProtected properties on filesystem items are now correctly dynamically updated when changed on newer Canon camera bodies.

• Increased the amount of data CascableCore will transfer to get a high-resolution preview of a NEF RAW image before falling back to a lower-resolution thumbnail. [CORE-387]

12.5.0

Camera Discovery Changes

• On iOS and iPadOS, if the user doesn't have an active WiFi connection, +[CBLNetworkConfigurationHelper suggestedInterfaceForCameraCommunication] will now iterate available local network interfaces and return the first one it finds with a valid IP address. This behaviour was already in place on macOS. [CORE-601]

• Partially as a consequence of the above, camera discovery now works correctly on iOS and iPadOS devices connected to the network only via Ethernet. [CORE-601]

• On all platforms, SSDP discovery requests will now be performed on all active network interfaces, not just the "primary" one. [CORE-601]

Bug Fixes

• +[CBLNetworkConfigurationHelper allInterfaces] no longer includes the loopback interface in its return value.

12.4.1

Changes

• Included an updated StopKit framework.

• The lowest supported iOS version is now iOS 12.

Bug Fixes

• Fixed an issue that would cause plugins to not be invoked for discovery if CascableCore decides not to natively search for cameras via network or USB. [CORE-496]

12.4

API Changes

• Added the CBLVideoFormatCompressionLevel enum and compressionLevel property to id <CBLVideoFormatPropertyValue>.

Bug Fixes

• Fixed an issue that would cause the CBLErrorCodeRequiresPhysicalInteraction error to not be thrown when failing to switch to stills mode due to the physical position of the stills/video switch on some Canon camera models.

• -setCurrentCommandCategories:completionCallback: now correctly waits for Canon cameras to switch in/out of the requisite mode before calling the completion handler, matching the documented behaviour.

12.3

New Property: Video Recording Format

The new CBLPropertyIdentifierVideoRecordingFormat property allows the ability to change the camera's video recording format on supported cameras. This property is currently implemented for Canon and Nikon cameras.

Objects for this property conform to id <CBLVideoFormatProperty> and values to id <CBLVideoFormatPropertyValue>, allowing the programmatic inspection of the frame rate and frame size of each format value. For users of our CascableCoreSwift library, you'll get a typed property with VideoFormatValue common values.

Camera Compatibility

• Added support for the Canon EOS R6 Mark II, EOS R100, EOS R8, and EOS R50. [CORE-558]

• Added support for the Nikon Z8 and Z30.

Bug Fixes

• Fixed a problem that would cause video recording to fail to start on newer Nikon cameras. [CORE-507]

• Fixed a problem that would cause still image shooting to get "stuck" on Canon cameras that'd been connected to other apps (such as EOS Utility) that configure the camera with a "PC" image destination before being connected to CascableCore without being switched off in between - CascableCore will clear that destination upon connection. A future update will enable full support for this shooting mode and the CBLPropertyIdentifierImageDestination property. [CORE-563]

12.2.4

Bug Fixes

• Fixed a crash that would occur on the "iOSOnMac" environment on Apple Silicon when searching for USB devices. Running CascableCore in this mode is currently experimental — please report any problems you find.

12.2.3

Bug Fixes

• Fixed a crash that could occur on macOS when disconnecting from a USB camera on macOS 13 Ventura. [CORE-399]

• Improved internal protection around the handling of messages on USB cameras on iOS. [CORE-400]

Other

• CascableCore now requires macOS 10.13 High Sierra or later.

12.2.2

Bug Fixes

• Fixed a bug that could cause live view to not start again after it'd been stopped on some Canon cameras. [CORE-394]
