To: devel at lists.lv2plug.in


LV2 4.0 is out.

More information about LV2 can be found at: http://lv2plug.in

This release is a significant one, fixing many problems and
introducing a new standard (though optional) method of depending on
LV2 extensions. In particular, it is now possible to install
system-wide extensions and build against them using a standard include
style (without requiring a central authority on extension package
names). The lv2core package, as of this version, includes a utility
called lv2config that makes this possible.
See http://lv2plug.in/docs/index.php?title=Using_Extensions_in_Code for details.

Changes (non-exhaustive):

 * Make doap:license suggested, but not required (for wrappers)
 * Define lv2:binary (MUST be in manifest.ttl)
 * Define lv2:majorVersion and lv2:minorVersion (MUST be in manifest.ttl)
 * Define lv2:documentation and use it to document lv2core
 * Add lv2:FunctionPlugin and lv2:ConstantPlugin classes
 * Move lv2:AmplifierPlugin under lv2:DynamicsPlugin
 * Loosen domain of lv2:optionalFeature and lv2:requiredFeature
   (to allow re-use in extensions)
 * Add generic lv2:Resource and lv2:PluginBase classes
 * Fix definition of lv2:minimum etc. (used for values, not scale points)
 * More precisely define properties with OWL
 * Move project metadata to manifest
 * Add lv2:enumeration port property.
 * Define run() pre-roll special case (sample_count == 0).

Release tarball is available at: http://lv2plug.in/spec/lv2core-4.0.tar.bz2
Documentation for LV2 core is available at:

Share and enjoy,
