ChangeLog

The clap wrapper is still an undergoing project, and we are not yet at a 1.0 release.

In August 2023, we started the process of tagging checkpoint versions either as we reached internal milestones or before we began new substantial development

0.11.0 (October 2024)

0.11.0 is under preparation; this draft changelog entry is as-of next f898db307fd81500b130088b2668bc2b5800ea07

• Windows Standalone substantial improvements

  • The Windows Standalone has a complete refactor
  • An audio/midi settings screen is in place
  • builds with various compilers and compiler versions
  • Properly defines unicode, handles UTF16 files
  • correctly factor CMake to not leak NOMINMAX, etc..
  • complies without warning even at high warning levels

• VST3

  • Test the VST3 extensively with linux hosts, and adjust
  • Implement several API points required for the VST3 in Ardour
  • Implement Steinberg::IPlugViewContentScaleSupport properly for scaling on Linux/Win
  • Implement SingleComponentEffect::getBusInfo to respond earlier, fixing an Ardour crash
  • clap param_refresh forces accurate VST3 parameter refresh
  • Correctly convert UTF8/UTF16 for internal strings, allowing clap parameter names with extended charsets to work in VST3
  • Fix an off-by-one error in stepped value conversions reflecting as VST3 stepped parameters

• AUV2

  • Allow a user specified INSTRUMENT_TYPE
  • Allow several strategies for constructing the AUV2 state stream, including one which allows compatibility with ausdk examples and another allowing compatibility with JUCE AUv2
  • Make the host name reported by the plugin consistent with the VST3
  • Fix a memory double-free in host get name.
  • clap param_refresh forces accurate AUv2 parameter refresh
  • AUv2 request resize makes host window resize
  • the MACOSX_EMBEDDED_CLAP option also uses that clap for plist creation

• Other wrapper fixes

  • request_resize doesn't block on can_resize
  • Mac standalone timer halts properly avoiding a crash-on-exit

• CMake and C++ infrastructure

  • Update CPM to 0.40.2
  • Update fmt to 11.0
  • Set flags correctly for C++ 20 builds
  • Change clap wrapper private/public flags to avoid Werror etc leaking to upstream targets
  • Support CMAKE_UNITY builds
  • All stand-alonee accurately set OUTPUT_NAME cmake property

0.10.1 (July 2024)

• Include one ARA cleanup commit for the VST3
• Only set CMAKE_MSVC_RUNTIME_LIBRARY (to static) if it is not set, allowing parent CMakeLists to make their own choice
• Include timer.cpp on Linux for VST3 SDK versions 3.7.9 or newer
• Update the version in CMakeLists.txt (in 0.10.0 it was still 0.9.2; now it is 0.10.1)

0.10.0 (July 2024)

• Add ARA support to the VST3 wrapper. If your underlying CLAP implements the ARA extension, your wrapped VST3 will correctly wrap the ARA API
• Add a small example of a clap plugin which builds self contained VST3, AUv2, etc...; build this in our CI pipeline as a test.
• Fix an off-by-one error in VST3 stepped params
• Fix a set of AUv2 crashes for plugins which do not implement the gui extension
• Add a build time option for the wrapper to statically locate clap_entry as opposed to via dlopen on self or remote clap.

0.9.1 (May 2024)

• Fixed to support VST3 program changes
• Implement offline processing for clap
• Implement the IsRecording flag for AUv2
• Allow child NSView to resize wrapper in AUv2

0.9.0 (Apr 2024)

• VST3 wrapper feature complete (Context menu support added)
• AUv2 wrapper feature complete
• Standalone working, in progress

0.8.0 (Mar 2024)

• Check active state before querying latency. Issue 229 by @Schroedingers-Cat
• VST3 programs / MIDI Program Changes
• fixed release build issues
• CMake Project Version reflected in version struct for CLAP host
• IMIDIMapping wasn't correctly used in VST3 wrapper

0.7.0 (Feb 2024)

• Audio Unit v2 (AUv2) wrapper is completed
• Uses CLAP 1.2.0 now
• Hostnames for different wrapper flavors are fixed
• fixed Cocoa namespaces clashes
• better unicode path handling on Windows
• Standalone App on Windows is now a proper application
• Various small bugfixes and improvements

0.5.0 (Sep 2023)

• A substantial rework of the CMake infrastructure, making the code more library like, able to download dependencies, and more
• Changes to allow operation as a top-level or subordinate cmake.
• Support for a variety of linking modes, including co-linked single products, included bundles, and standalone plugins
• A shell for AUv2 work
• Allow builds back to macOS 10.11; Set the default build target to 10.13
• Implement linux Timer and FD support, allowing full linux implementation of many test cases
• Turn on -Wall -Wextra -Wpedantic -Werror on linux
• Suppress CLAP Param Change events for parameters under edit
• Implement param to/from string VST3 API
• Output note ports in CLAP become output event queues in VST3; CLAP_EVENT_NOTE_* is transmitted out (but note expressions and MIDI are not yet)
• Several small crash and lifecycle fixes on various OSes

0.4.0 (Aug 2023)

• 0.4.0 is the first tagged release.
• It can create a win/mac VST3 with a subset of the spec which runs with a remote clap.
• It implements the entire clap host API required to proxy to multiple formats.
