To disable a profile, call setProfileEnablement with zero channels. + +**Rationale** + +The new API is simpler, more compact, and more consistent, as it now mirrors +the signature of Device::sendProfileEnablement. + + +## Change + +OpenGLContext::getRenderingScale() has been changed to include the effects of +AffineTransforms on all platforms. + +**Possible Issues** + +Applications that use OpenGLContext::getRenderingScale() and also have scaling +transformations that affect the context component's size may render incorrectly. + +**Workaround** + +Adjust rendering code by dividing the reported scale with the user specified +transformation scale, if necessary. + +**Rationale** + +The previous implementation resulted in inconsistent behaviour between Windows +and the other platforms. The main intended use-case for getRenderingScale() is +to help determine the number of physical pixels covered by the context +component. Since plugin windows will often use AffineTransforms to set up the +correct rendering scale, it makes sense to include these in the result of +getRenderingScale(). + + +## Change + +Components that have setMouseClickGrabsKeyboardFocus() set to false will not +accept or propagate keyboard focus to parent components due to a mouse click +event. This is now true even if the mouse click event happens in a child +component with setMouseClickGrabsKeyboardFocus (true) and +setWantsKeyboardFocus (false). + +**Possible Issues** + +Components that rely on child components propagating keyboard focus from a +mouse click, when those child components have setMouseClickGrabsKeyboardFocus() +set to false, will no longer grab keyboard focus. + +**Workaround** + +Add a MouseListener to the component receiving the click and override the +mouseDown() method in the listener. In the mouseDown() method call +Component::grabKeyboardFocus() for the component that should be focused. + +**Rationale** + +The intent of setMouseClickGrabsKeyboardFocus (false) is to reject focus changes +coming from mouse clicks even if the component is otherwise capable of receiving +keyboard focus. + +The previous behaviour could result in surprising focus changes when a child +component was clicked. This manifested in the focus seemingly disappearing when +a PopupMenu item added to a component was clicked. + + +## Change + +The NodeID argument to AudioProcessorGraph::addNode() has been changed to take +a std::optional. + +**Possible Issues** + +The behavior of any code calling AudioProcessorGraph::addNode(), that explicitly +passes a default constructed NodeID or a NodeID constructed with a value of 0, +will change. Previously these values would have been treated as a null value +resulting in the actual NodeID being automatically determined. These will now +be treated as requests for an explicit value. + +**Workaround** + +Either remove the explicit NodeID argument and rely on the default argument or +pass a std::nullopt instead. + +**Rationale** + +The previous version prevented users from specifying a NodeID of 0 and resulted +in unexpected behavior. + + +## Change + +The signature of DynamicObject::writeAsJSON() has been changed to accept a +more extensible JSON::FormatOptions argument. + +**Possible Issues** + +Code that overrides or calls this function will fail to compile. + +**Workaround** + +Update the signatures of overriding functions. Use FormatOptions::getIndentLevel() +and FormatOptions::getMaxDecimalPlaces() as necessary. To find whether the output +should be multi-line, compare the result of FormatOptions::getSpacing() with +JSON::Spacing::multiLine. + +Callers of the function can construct the new argument type using the old +arguments accordingly + +``` +JSON::FormatOptions{}.withIndentLevel (indentLevel) + .withSpacing (allOnOneLine ? JSON::Spacing::singleLine + : JSON::Spacing::multiLine) + .withMaxDecimalPlaces (maximumDecimalPlaces); +``` + +**Rationale** + +The previous signature made it impossible to add new formatting options. Now, +if we need to add further options in the future, these can be added to the +FormatOptions type, which will not be a breaking change. + + +# Version 7.0.9 + +## Change + +CachedValue::operator==() will now emit floating point comparison warnings if +they are enabled for the project. + +**Possible Issues** + +Code using this function to compare floating point values may fail to compile +due to the warnings. + +**Workaround** + +Rather than using CachedValue::operator==() for floating point types, use the +exactlyEqual() or approximatelyEqual() functions in combination with +CachedValue::get(). + +**Rationale** + +The JUCE Framework now offers the free-standing exactlyEqual() and +approximatelyEqual() functions to clearly express the desired semantics when +comparing floating point values. These functions are intended to eliminate +the ambiguity in code-bases regarding these types. However, when such a value +is wrapped in a CachedValue the corresponding warning was suppressed until now, +making such efforts incomplete. + + +# Version 7.0.8 + +## Change + +DynamicObject::clone now returns unique_ptr instead of +ReferenceCountedObjectPtr. + +**Possible Issues** + +Overrides of this function using the old signature will fail to compile. +The result of this function may need to be manually converted to a +ReferenceCountedObjectPtr. + +**Workaround** + +Update overrides to use the new signature. +If necessary, manually construct a ReferenceCountedObjectPtr at call sites. + +**Rationale** + +It's easy to safely upgrade a unique_ptr to a shared/refcounted pointer. +However, it's not so easy to convert safely in the opposite direction. +Generally, returning unique_ptrs rather than refcounted pointers leads to more +flexible APIs. + + +# Version 7.0.7 + +## Change + +The minimum supported CMake version is now 3.22. + +**Possible Issues** + +It will no longer be possible to configure JUCE projects with CMake versions +between 3.15 and 3.21 inclusive. + +**Workaround** + +No workaround is available. Newer versions of CMake can be obtained from the +official download page, or through system package managers. + +**Rationale** + +Moving to CMake 3.22 improves consistency with the Projucer's Android exporter, +which already requires CMake 3.22. It also allows us to make use of the +XCODE_EMBED_APP_EXTENSIONS property (introduced in CMake 3.21), fixing an +issue when archiving AUv3 plugins. + + +# Version 7.0.6 + +## Change + +Thread::wait and WaitableEvent::wait now take a double rather than an int to +indicate the number of milliseconds to wait. + +**Possible Issues** + +Calls to either wait function may trigger warnings. + +**Workaround** + +Explicitly cast the value to double. + +**Rationale** + +Changing to double allows sub-millisecond waits which was important for +supporting changes to the HighResolutionTimer. + + +## Change + +RealtimeOptions member workDurationMs was replaced by three optional member +variables in RealtimeOptions, and all RealtimeOptions member variables were +marked private. + +**Possible Issues** + +Trying to construct a RealtimeOptions object with one or two values, or access +any of its member variables, will no longer compile. + +**Workaround** + +Use the withMember functions to construct the object, and the getter functions +to access the member variable values. + +**Rationale** + +The new approach improves the flexibility for users to specify realtime thread +options on macOS/iOS and improves the flexibility for the API to evolve without +introducing further breaking changes. + + +## Change + +JUCE module compilation files with a platform suffix are now checked case +insensitively for CMake builds. + +**Possible Issues** + +If a JUCE module compilation file ends in a specific platform suffix but does +not match the case for the string previously checked by the CMake +implementation, it may have compiled for all platforms. Now, it will only +compile for the platform specified by the suffix. + +**Workaround** + +In most cases this was probably a bug, in other cases rename the file to remove +the platform suffix. + +**Rationale** + +This change improves consistency between the Projucer and CMake integrations. + + +## Change + +An undocumented feature that allowed JUCE module compilation files to compile +for a specific platform or subset of platforms by declaring the platform name +followed by an underscore, was removed. + +**Possible Issues** + +If a JUCE module compilation file contains a matching platform suffix followed +by an underscore and is loaded by the Projucer it will no longer compile for +just that platform. + +**Workaround** + +Use the suffix of the name only. If the undocumented feature was used to select +multiple platforms, make multiple separate files for each of the required +platforms. + +**Rationale** + +This change improves consistency between the Projucer and CMake integrations. +Given the functionality was undocumented, the ease of a workaround, and the +added complexity required for CMake support, the functionality was removed. + + +## Change + +Unique device IDs on iOS now use the OS provided 'identifierForVendor'. +OnlineUnlockStatus has been updated to handle the iOS edge-case where a device +ID query might return an empty String. + +**Possible Issues** + +The License checks using InAppPurchases, getLocalMachineIDs(), and +getUniqueDeviceID() may return an empty String if iOS 'is not ready'. This can +occur for example if the device has restarted but has not yet been unlocked. + +**Workaround** + +InAppPurchase has been updated to handle this and propagate the error +accordingly. The relevant methods have been updated to return a Result object +that can be queried for additional information on failure. + +**Rationale** + +Apple have introduced restrictions on device identification rendering our +previous methods unsuitable. + + +## Change + +AudioProcessor::getAAXPluginIDForMainBusConfig() has been deprecated. + +**Possible Issues** + +Any AudioProcessor overriding this method will fail to compile. + +**Workaround** + +- Create an object which inherits from AAXClientExtensions. +- In the object override and implement getPluginIDForMainBusConfig(). +- In the AudioProcessor override getAAXClientExtensions() and return a pointer + to the object. + +**Rationale** + +Additional AAX specific functionality was required in the audio processor. +Rather than continuing to grow and expand the AudioProcessor class with format +specific functionality, separating this concern into a new class allows for +greater expansion for those that need it without burdening those that don't. +Moving this function into this class improves consistency both with the new +functionality and with similar functionality for the VST2 and VST3 formats. + + +## Change + +Unique device IDs on Windows have been updated to use a more reliable SMBIOS +parser. The SystemStats::getUniqueDeviceID function now returns new IDs using +this improved parser. Additionally, a new function, +SystemStats::getMachineIdentifiers, has been introduced to aggregate all ID +sources. It is recommended to use this new function to verify any IDs. + +**Possible Issues** + +The SystemStats::getUniqueDeviceID function will return a different ID for the +same machine due to the updated parser. + +**Workaround** + +For code that previously relied on SystemStats::getUniqueDeviceID, it is advised +to switch to using SystemStats::getMachineIdentifiers() instead. + +**Rationale** + +This update ensures the generation of more stable and reliable unique device +IDs, while also maintaining backward compatibility with the previous ID +generation methods. + + +## Change + +The Grid layout algorithm has been slightly altered to provide more consistent +behaviour. The new approach guarantees that dimensions specified using the +absolute Px quantity will always be correctly rounded when applied to the +integer dimensions of Components. + +**Possible Issues** + +Components laid out using Grid can observe a size or position change of +/- 1px +along each dimension compared with the result of the previous algorithm. + +**Workaround** + +If the Grid based graphical layout is sensitive to changes of +/- 1px, then the +UI layout code may have to be adjusted to the new algorithm. + +**Rationale** + +The old Grid layout algorithm could exhibit surprising and difficult to control +single pixel artifacts, where an item with a specified absolute size of +e.g. 100px could end up with a layout size of 101px. The new approach +guarantees that such items will have a layout size exactly as specified, and +this new behaviour is also in line with CSS behaviour in browsers. The new +approach makes necessary corrections easier as adding 1px to the size of an +item with absolute dimensions is guaranteed to translate into an observable 1px +increase in the layout size. + + +## Change + +The k91_4 and k90_4 VST3 layouts are now mapped to the canonical JUCE 9.1.4 and +9.0.4 AudioChannelSets. This has a different ChannelType layout than the +AudioChannelSet previously used with such VST3 SpeakerArrangements. + +**Possible Issues** + +VST3 plugins that were prepared to work with the k91_4 and k90_4 +SpeakerArrangements may now have incorrect channel mapping. The channels +previously accessible through ChannelType::left and right are now accessible +through ChannelType::wideLeft and wideRight, and channels previously accessible +through ChannelType::leftCentre and rightCentre are now accessible through +ChannelType::left and right. + +**Workaround** + +Code that accesses the channels that correspond to the VST3 Speakers kSpeakerL, +kSpeakerR, kSpeakerLc and kSpeakerRc needs to be updated. These channels are now +accessible respectively through ChannelTypes wideLeft, wideRight, left and +right. Previously they were accessible respectively through left, right, +leftCentre and rightCentre. + +**Rationale** + +This change allows developers to handle the 9.1.4 and 9.0.4 surround layouts +with one codepath across all plugin formats. Previously the +AudioChannelSet::create9point1point4() and create9point0point4() layouts would +only be used in CoreAudio and AAX, but a different AudioChannelSet would be used +in VST3 even though they were functionally equivalent. + + +## Change + +The signatures of the ContentSharer member functions have been updated. The +ContentSharer class itself is no longer a singleton. + +**Possible Issues** + +Projects that use the old signatures will not build until they are updated. + +**Workaround** + +Instead of calling content sharer functions through a singleton instance, e.g. + ContentSharer::getInstance()->shareText (...); +call the static member functions directly: + ScopedMessageBox messageBox = ContentSharer::shareTextScoped (...); +The new functions return a ScopedMessageBox instance. On iOS, the content +sharer will only remain open for as long as the ScopedMessageBox remains alive. +On Android, this functionality will be added as/when the native APIs allow. + +**Rationale** + +The new signatures are safer and easier to use. The ScopedMessageBox also +allows content sharers to be dismissed programmatically, which wasn't +previously possible. + + +## Change + +The minimum supported AAX library version has been bumped to 2.4.0 and the +library is now built automatically while building an AAX plugin. The +JucePlugin_AAXLibs_path preprocessor definition is no longer defined in AAX +plugin builds. + +**Possible Issues** + +Projects that use the JucePlugin_AAXLibs_path definition may no longer build +correctly. Projects that reference an AAX library version earlier than 2.4.0 +will fail to build. + +**Workaround** + +You must download an AAX library distribution with a version of at least 2.4.0. +Use the definition JucePlugin_Build_AAX to check whether the AAX format is +enabled at build time. + +**Rationale** + +The JUCE framework now requires features only present in version 2.4.0 of the +AAX library. The build change removes steps from the build process, and ensures +that the same compiler flags are used across the entire project. + + +## Change + +The implementation of ColourGradient::createLookupTable has been updated to use +non-premultiplied colours. + +**Possible Issues** + +Programs that draw transparent gradients using the OpenGL or software +renderers, or that use lookup tables generated from transparent gradients for +other purposes, may now produce different results. + +**Workaround** + +For gradients to render the same as they did previously, transparent colour +stops should be un-premultiplied. For colours with an alpha component of 0, it +may be necessary to specify appropriate RGB components. + +**Rationale** + +Previously, transparent gradients rendered using CoreGraphics looked different +to the same gradients drawn using OpenGL or the software renderer. This change +updates the OpenGL and software renderers, so that they produce the same +results as CoreGraphics. + + +## Change + +Projucer-generated MSVC projects now build VST3s as bundles, rather than as +single DLL files. + +**Possible Issues** + +Build workflows that expect the VST3 to be a single DLL may break. + +**Workaround** + +Any post-build scripts that expect to copy or move the built VST3 should be +updated so that the entire bundle directory is copied/moved. The DLL itself +can still be located and extracted from within the generated bundle if +necessary. + +**Rationale** + +Distributing VST3s as single files was deprecated in VST3 v3.6.10. JUCE's CMake +scripts already produce VST3s as bundles, so this change increases consistency +between the two build systems. + + +# Version 7.0.3 + +## Change -Change ------- The default macOS and iOS deployment targets set by the Projucer have been increased to macOS 10.13 and iOS 11 respectively. -Possible Issues ---------------- +**Possible Issues** + Projects using the Projucer's default minimum deployment target will have their minimum deployment target increased. -Workaround ----------- +**Workaround** + If you need a lower minimum deployment target then you must set this in the Projucer's Xcode build configuration settings. -Rationale ---------- +**Rationale** + Xcode 14 no longer supports deployment targets lower than macOS 10.13 and iOS 11. -Change ------- +## Change + The ARA SDK expected by JUCE has been updated to version 2.2.0. -Possible Issues ---------------- +**Possible Issues** + Builds using earlier versions of the ARA SDK will fail to compile. -Workaround ----------- +**Workaround** + The ARA SDK configured in JUCE must be updated to version 2.2.0. -Rationale ---------- -Version 2.2.0 is the latest official release of the ARA SDK. +**Rationale** + +# Version 2.2.0 is the latest official release of the ARA SDK. -Change ------- +## Change + The Thread::startThread (int) and Thread::setPriority (int) methods have been removed.
