-------------------------------------------- 2013-05-22: Release 0.27 -------------------------------------------- We are pleased to present stable release 0.27 of LibLo, the lightweight, easy to use implementation of the Open Sound Control protocol. Open Sound Control (OSC) is a protocol for communication among computers, sound synthesizers, and other multimedia devices that is designed for use over modern network transports. This is the first release in quite some time, and includes several major features and improvements since the 0.26 release, particularly related to bundles, multicast, and TCP support. Features include: - Support for sending and receiving nested bundles, including ref-counted memory handling for bundled messages. - Support for multicast in oscdump and oscsend tools. - Callbacks for bundle handling. - Select desired network interface for multicast. - Fix blocking semantics of lo_server_wait() / lo_server_recv(). - Make inclusion of threading-related code optional. - Basic compilation script for Android. - Allow to optionally disable server dispatch queueing at runtime. (In this case messages are dispatched immediately even if they are timestamped for later.) - Support bidirectional use of TCP ports using lo_send_from(). - Add SLIP protocol support for packetization when sending and receiving with TCP. - Allow to enable the TCP_NODELAY flag on TCP sockets. Bug fixes include: - Fixed timestamp serialization. - Fixed blob padding and char-type padding. - Close sockets properly under Windows. - Fix multicast under Windows. - Fix TCP reception blocking behaviour, such that a message can span multiple calls to recv(). - Correct printing of blob bytes. - Only call getnameinfo() when requested.

Open Sound Control (OSC) is a protocol for communication among computers, sound synthesizers, and other multimedia devices that is designed for use over modern network transports. This release marks the first release of LibLo under the LGPL license version 2.1 or later, allowing the use of LibLo in non-GPL applications as long as it is dynamically linked such that the LibLo portion of the application can remain freely modifiable. We hope that this will allow compatibility with a wider variety of audio applications and encourage the use of open protocols even in commercial software. (This change was motivated by receiving a number of requests for special permission for the use of LibLo in non-GPL software.) This release also introduces some new features, such as the ability to use custom transports, proper TCP multi-session support, access to bundle timestamp information, and wider C compiler compatibility. Details: - Change license to LGPL 2.1 or later. - Add return codes to all functions that may fail. - Fix memory leaks in lo_address_new_from_url(), dispatch_method(), lo_url_get_path() - Move lo_arg_size(), lo_get_path(), lo_arg_host/network_endian() back to lo_lowlevel.h. - Expose the lo_server_dispatch_data() function as public, making it possible to react to messages contained in an arbitrary block of memory. (i.e., allows use with custom transport protocols) - Get protocol by ID number. - Keep TCP sessions open, and automatically track multiple open sessions in a data structure. - Allow access to bundle timestamp information. - Fix bug in lo_timetag_diff(). - Change the value of LO_TT_IMMEDIATE to correspond with the OSC specification. - Enable SO_REUSEPORT when initializing a multicast server. - Update the "soname" describing API/ABI compatibility. - Update documentation and various bug fixes. - Compiles under MSVC, avoiding the use of gcc-isms when not using gcc.

Open Sound Control (OSC) is a protocol for communication among computers, sound synthesizers, and other multimedia devices that is optimized for modern networking technology. This release brings several new features, including support for broadcast messages, multicast UDP groups, message deserialisation, and input validation. Details: - Check for buffer overflows - Added oscsend and oscdump command-line tools - Added lo_message_add_varargs() for variable-argument C functions. - Added lo_bundle_free_messages() - Bug fix for pattern matching. (curly braces) - Broadcast support - Added lo_message_deserialise() - Multicast support - Fixes for compiling on OS X - General bug fixes Contributions by: - Camille Troillard - Chris Hixon - Kentaro Fukuchi - Dave Robillard - Nicolas Humfrey - Stephen Sinclair Please feel free to download it at SourceForge: http://downloads.sourceforge.net/liblo/liblo-0.25.tar.gz Or read the online documentation: http://liblo.sourceforge.net Stephen Sinclair LibLo maintainer -------------------------------------------- 2007-03-21: Release 0.24 -------------------------------------------- About: LibLO is a lightweight library for handling the sending and receiving of messages according to the Open Sound Control (OSC) protocol on POSIX systems. Changes: lo_server_get_protocol() and lo_address_get_protocol() were added. Tests for lo_address_get_* were added to the test tool. Several compiler warnings were fixed. The address for package bug reports was changed. lo_blob_new() was changed to take const void*. The getnameinfo() method of getting hostname is disabled when IPv6 is disabled. A Unix server socket is now unlinked when it is closed. The size of a Unix socket path is checked properly. -------------------------------------------- 2006-01-27: Release 0.23 -------------------------------------------- Liblo, the Lite OSC library, is an implementation of the Open Sound Control protocol for POSIX systems*.
