Full Changelog: v3.2.4...v3.3.0

ossia score 3.3.0 is a major release featuring a host of new capabilities.

New features

• Devices: initial work in allowing devices to specify the resources they are using such as ports, etc. in a more structured way.
• Devices: Move the Device QML object implementation from score to libossia ; add Device.read/write to HTTP device
• Devices: support for direct NeoPixel LED control over SPI.
• Devices: support for the Sh4lt protocol which supersedes Shmdata. Thanks @nicobou!
• Graphics: Add support for GPU decoding of RGB24 and BGR24 textures, useful for Qt Animation qtrle files
• Graphics: Efficient geometry filtering pipeline. Introduction of a Geometry Filter object which is able to inject transformations in the vertex shader stage and support for geometry processing relationships in the graphics thread.
• Graphics: Sprite Reader object for all your retro-gaming needs
• Graphics: Support for loading point clouds
• JS: Add utility functions to convert between types
• Mappings: Add a ArrayGen object to generate arrays easily
• Mappings: add Combine and Spread objects to enable simpler processing and recombination of values into arrays
• Mappings: add initial gesture detection support through the Puara Gestures library
• Mappings: Mapping Tool object with a lot of feature for mapping data such as deadzone detection, re-scaling, etc.
• Math: Fix live editing of expression in arraygen / arraymap
• MIDI: initial support for computer keyboard input
• MIDI: Virtual ports will now be scanned
• OSC: add support for the SpatGRIS OSC API directly through a new device
• OSC: allow to expose a local OSC device as a TCP server
• OSC: allow to expose a local OSC device over an OSCQuery port
• OSCQuery: handle buggy HTTP implementations that do not properly close connection
• OSCQuery: implement dense mode which packs values according to an OSCQuery spec, especially useful for resource-constrained devices
• Pipewire Respect PIPEWIRE_LATENCY environment variable
• Platforms: add CI script based on native packages for Debian Trixie
• Platforms: prevent the Intel version to run on AppleSilicon Macs as it is thoroughly incompatible
• Platforms: support for building in C++23 mode
• Platforms: support for macOS 15 and Xcode 16, clang-18, clang-19, Fedora 41
• PureData / libpd: revert to a version with working audio
• UI: Add icon for upcoming AI-based processes. Thanks @aklevy!
• UI: Add support for slowing down slider changes with CTRL / Command
• UI: implement reset-to-default-value-on-double-click on most central view UI controls
• UI: make the middle column resizeable in the Device dialog. Thanks @samamou!
• UI: tighter UI style
• VST3: Support for VST3 on AArch64 platforms

Improvements and bug fixes

• Audio: Fix saving / loading of propagate attribute
• Audio: many fixes to quantification.
• Audio: Various fixes for VST and LV2
• Automation: Fix that changing the address would reset the scale if it was a pattern
• Avnd: dynamic ports improvements
• Avnd: support for texture sizes in CPU texture filters
• BLE: Fix support on Win32 and Flatpak
• Core: Be more lenient when reloading if a cable isn't present in a save file due to dynamic operations
• Core: finish porting all the plug-ins written in the previous "Fx" API to Avendish which is now the one and only officially supported API for making ossia add-ons.
• Curve rendering: optimizations when we have more than a thousand points.
• Devices: Add a more optimized device_parameter implementation when we know the type beforehand
• Devices: DNSSD: force every execution to execute over the same thread as Avahi is not thread-safe nor reentrant
• Devices: Do not try to infer the min / max if things are patterns
• Execution: domain and range improvements, allow value ports with ranges, fix LFO output range
• Graphics: Fix missing Spout I/O on Windows
• Graphics: fix that shmdata input do not reconnect when writer quits
• Graphics: improve the amount of recomputations needed for geometry updates
• Images: fix render shader which had broken
• Items: Send signals to release mouse if a graphics item is deleted while being grabbed
• JS: thread safety fixes and improvements
• MIDI: fix some note-off cases that were not handled.
• MIDI: Use the proper app name in MIDI APIs
• Platform: Improve support of QT_QPA_PLATFORM=minimal
• Raw I/O: improve PWM support
• Scenario: creating a state by double-click will now automatically make it auto-started
• Spline: Update and fix small bugs in tinyspline library
• UI: Add documentation links to most processes and devices. The process inspector and device dialog now have direct links to the relevant help pages.
• UI: Be more permissive with looping slot issues
• UI: fix connected port look in hi-dpi mode
• UI: fix the ugly ampersand that appeared some Qt versions ago.
• UI: Fix UI not resizing when a port is added to a node
• UI: LineEdit: improve relayout in nodes
• UI: make sure that controls always show up no matter what in the inspector panel
• UI: port UI improvements in inspector ; show more port names and always show port list.
• UI: respect Alt-key magnetism behaviour when dropping a state.
• UI: Update scene when node size changes to prevent background artefacts
• UI: use double-precision for storing slider data as it caused visible precision issues with large ranges
• VST / VST3: Disable GUI when running under wayland as plug-ins will crash
• VST and friends: Use the actual processed samples as timing information instead of a computation depending on speed
• YSFX: cmake improvements
• Many, many other bugfixes and code improvements...
