0.1.1 (2016-01-27)
------------------
Note: This release does NOT change the libserialport API or ABI in
backwards-incompatible ways. Programs using libserialport should
continue to work fine without recompiling or relinking.
* New API calls:
- sp_get_port_description(): Obtain a user friendly port description.
- sp_get_port_transport(): Obtain the underlying transport type.
- sp_get_port_usb_bus_address(): Obtain the USB bus number & device address.
- sp_get_port_usb_vid_pid(): Obtain the USB VID and PID.
- sp_get_port_usb_manufacturer(): Obtain the USB manufacturer string.
- sp_get_port_usb_product(): Obtain the USB product string.
- sp_get_port_usb_serial(): Obtain the USB serial number string.
- sp_get_port_bluetooth_address(): Obtain the Bluetooth MAC address.
- sp_blocking_read_next(): Read bytes from the specified serial port,
returning as soon as any data is available.
* API related additions:
- enum sp_mode: Add SP_MODE_READ_WRITE.
- Add enum sp_transport with the following enum entries:
SP_TRANSPORT_NATIVE, SP_TRANSPORT_USB, SP_TRANSPORT_BLUETOOTH.
* Fix the build on platforms where port enumeration and/or port
metadata is not available or implemented.
* Build system:
- Don't set/override "user variables" such as CFLAGS or LDFLAGS, since
those are meant to be controlled by the "user" (bug #577).
- Modernize and cleanup autotools setup.
* Remove trailing commas in libserialport.h enum definitions to allow
the code to build with the -pedantic compiler option.
* Fix various issues to allow successful builds with -std=c99.
* Fix various (non-fatal) compiler warnings.
* Fix various memory leaks (bug #419, among others).
* Fix a potential overflow of the timeout parameter of poll().
* Fix ReadFile() ERROR_IO_PENDING in sp_nonblocking_read() (bug #707).
* Fix a glibc >= 2.20 compiler warning for deprecated _BSD_SOURCE (bug #716).
* Rename a 'signals' parameter to 'signal_mask' to avoid a conflict with Qt.
* Fix two potential segfaults in sp_get_port_handle() and sp_get_config_*()
(which only occurred if the user incorrectly passed in a NULL argument).
* sp_list_ports(): Actually set list_ptr NULL as documented.
* Use "Port not open" debug message when a closed port is used (bug #710).
* Linux:
- The libudev requirement has been dropped (/sys is now used directly).
- Fix a build issue in the get_termios_get_ioctl() call (bug #396).
- Fix sp_flush() so that it only flushes the requested buffers.
- Fix a build error if BOTHER is not available (bug #363).
- If present, add the USB "description" for better port identification.
- Handle the case when /sys/class/tty/ entries are not symlinks.
* Windows:
- MinGW-w64 (mingw-w64.sf.net) is now required for building, and MinGW
(mingw.org) is no longer supported (bug #393).
- Fix a build issue due to a missing <initguid.h> #include.
- Fix a build issue due to the missing -lsetupapi linker argument.
- Use libtool's -no-undefined option to allow shared (DLL) builds.
- Fix a compile error due to multiply or not defined GUIDs (bug #416).
- Fix a build issue related to the SP_PRIV/SP_API macros (bug #553).
- Fix a bug where an uninitialized pointer was free()'d (bug #512).
- Fix a bug wrt the SetupDiOpenDevRegKey() return code (bug #499).
- Fix a bug wrt restart of RX/error wait operations after read (bug #421).
- Fix a bug wrt WaitCommEvents() and/or fAbortOnError handling (bug #341).
- Fix USB iSerial queries on USB composite devices.
- Strip CR/LF from end of system error messages (bug #585).
- Avoid unnecessary calls to the SetCommTimeouts() function (bug #586).
- Fix a bug in the Windows implementation of sp_blocking_read_next().
- Fix an ERROR_SEM_TIMEOUT related issue in sp_blocking_write().
* FreeBSD:
- Implement serial port enumeration for FreeBSD systems.
* Android:
- Fix a portability issue wrt the unavailable 'serial_struct' (bug #376).
- Fix a portability issue wrt a readlinkat() call (bug #377).
* Mac OS X:
- Fix port listing on Mac OS X 10.11 (El Capitan).
* README: Various documentation updates and fixes.
* AUTHORS: Add/update list of contributors.
* Doxygen API docs: Various documentation updates and fixes.
0.1.0 (2014-05-06)
