Hi, This is an announcement for the second official release of alsa-gobject project[1]. The release is available in below URL: * https://github.com/alsa-project/alsa-gobject/releases/tag/v0.2.0 It includes some enhancements and bug fixes. * Some implementations of GLib GQuark is exported as error domain and corresponding enumerations are added. This improves error reporting in each libraries. It closes issue #47[2]. * Selection of substream in ALSARawmidi.StreamPair.open() now works well. This closes issue #53[3]. * Prototypes of some methods in ALSACtl.Card object for data of TLV(Type-Length-Value) in ALSA control interface are changed without backward compatibility. Corresponding exported symbols are maintained by new symbol version. In detail, refer to #55[4]. * Error handling is changed so that function call with invalid argument just returns with warnings instead of generating GError, according to convention for GLib application. Memory allocation failure is supposed to be unrecoverable error and aborts program, as well. * It's possible to build for older version Linux kernel, therefore build dependency is now Linux kernel v4.5 or later. For the new release, documentations are also updated. They're auto-generated by gtk-doc[5] from function annotations: * https://alsa-project.github.io/alsa-gobject-docs/ The new release of Rust crates are available as well in repository. They're auto-generated by gtk-rs/gir[6]: * https://github.com/alsa-project/alsa-gobject-rs/releases/tag/v0.2.0 I note that ALSA PCM interface is not supported yet.
