LSP (Linux Studio Plugins) is a collection of open-source plugins currently compatible with CLAP, LADSPA, LV2, VST2/LinuxVST, VST3 and JACK standalone formats.
The basic idea is to fill the lack of good and useful plugins under the GNU/Linux platform.
After some contributions to other open source projects the decision was made to implement separate and independent plugin distribution.

minor feature:
Implemented default OpenGL rendering engine for the UI for X11-based operating systems. The rendering engine can be switched back to Cairo by setting LSP_WS_LIB_GLXSURFACE=off environment variable. Added possibility to use custom scaling for each plugin bundle. Added highlighting of active item in file navigator nearby sample preview. Several optimizations related to scaling widgets in the graphical toolkit library. Updated several core libraries for better support of MacOS. Additional AVX-512 optimizations of code DSP library. Several changes in Sampler and Multisampler plugin series: Implemented possibility to Drag Drop drumkits, SFZ files and LSPC files directly to the plugin's window for import purpose. Muting button does not disable the listen button. Added 'velocity' button that allows to disable or enable the volume control of a sample by the velocity value of the MIDI note. Added automatic instrument name assign same to current sample file name if UI behavior option 'Take instrument name from file' is enabled and the name of instrument is empty or similar to currently selected sample file. Updated several labels in the UI. Added workaround for Renoise host related to latency reporting by VST2 and VST3 plugins on state load. unnecessary output parameter cleanup when importing configuration that caused several when importing plugin state from file. regression related to impossibility of setting proper values for in several parameters in the VST3 plugin format. some typos in UI.

minor bugfix:
Implemented Referencer plugin series.
Added "Automatically load files when navigating file list" feature that allows to automatically load files when navigating file list nearby the loaded sample.
Added shared memory sends and returns to Mixer plugin series.
Added shared memory returns to A/B Tester plugin series.
Added tracking of maximum values to the Spectrum Analyzer plugin series.
Several fixes around UI Widgets.
Added 'Stop' button for file preview in plugins tha allow audio file loading:
Impulse Responses;
Impulse Reverb;
Room Builder;
Sampler and Multisampler;
Trigger.
Better support of Enter and Escape keys in dialogs.
Yet more SIMD and AVX-512 optimizations in the DSP libray.
AVX-512 optimizations are now enabled for AMD Ryzen 7000 processor series and later.
DSP library now supports build for MacOS on Apple M1 and later chips.
Fixed possible file name loss on deactivated plugins for all modern plugin formats.
Fixed imprecise spectrum graph and left/right channel desynchronization when rapidly changing the frequency of filter in Parametric Equalizer plugin series.
Fixed the behaviour of the 'Inspect' button in the VST3 version of Parametric Equalizer plugin series. The fix may cause some regressions in user sessions by enabling the inpection of the first filter.
Fixed regression related to he AArch64 version of plugins that freezed the host.
