+
+2013-07-11: v1.0.16
+* Add hotplug support for Darwin and Linux (#9)
+* Add superspeed endpoint companion descriptor support (#15)
+* Add BOS descriptor support (#15)
+* Make descriptor parsing code more robust
+* New libusb_get_port_numbers API, this is libusb_get_port_path without

+* Many other bug fixes and improvements
+The (#xx) numbers are libusbx issue numbers, see ie:
+https://github.com/libusbx/libusbx/issues/9
+
+2013-04-15: v1.0.15
+* Improve transfer cancellation and avoid short read failures on broken descriptors
+* Filter out 8-bit characters in libusb_get_string_descriptor_ascii()
+* Add WinCE support
+* Add library stress tests
+* Add Cypress FX3 firmware upload support for fxload sample
+* Add HID and kernel driver detach support capabilities detection
+* Add SuperSpeed detection on OS X
+* Fix bInterval value interpretation on OS X
+* Fix issues with autoclaim, composite HID devices, interface autoclaim and
+  early abort in libusb_close() on Windows. Also add VS2012 solution files.
+* Improve fd event handling on Linux
+* Other bug fixes and improvements
+
+2012-09-26: v1.0.14
+* Reverts the previous API change with regards to bMaxPower.
+  If this doesn't matter to you, you are encouraged to keep using v1.0.13,
+  as it will use the same attribute as v2.0, to be released soon.
+* Note that LIBUSBX_API_VERSION is *decreased* to 0x010000FF and the previous
+  guidelines with regards to concurrent use of MaxPower/bMaxPower still apply.
+
+2012-09-20: v1.0.13
+* [MAJOR] Fix a typo in the API with struct libusb_config_descriptor where
+  MaxPower was used instead of bMaxPower, as defined in the specs. If your 
+  application was accessing the MaxPower attribute, and you need to maintain
+  compatibility with libusb or older versions, see APPENDIX A below.
+* Fix broken support for the 0.1 -> 1.0 libusb-compat layer
+* Fix unwanted cancellation of pending timeouts as well as major timeout related bugs
+* Fix handling of HID and composite devices on Windows
+* Introduce LIBUSBX_API_VERSION macro
+* Add Cypress FX/FX2 firmware upload sample, based on fxload from
+  http://linux-hotplug.sourceforge.net
+* Add libusb0 (libusb-win32) and libusbK driver support on Windows. Note that while
+  the drivers allow it, isochronous transfers are not supported yet in libusbx. Also
+  not supported yet is the use of libusb-win32 filter drivers on composite interfaces
+* Add support for the new get_capabilities ioctl on Linux and avoid unnecessary
+  splitting of bulk transfers
+* Improve support for newer Intel and Renesas USB 3.0 controllers on Windows
+* Harmonize the device number for root hubs across platforms
+* Other bug fixes and improvements
+
+2012-06-15: v1.0.12
+* Fix a potential major regression with pthread on Linux
+* Fix missing thread ID from debug log output on cygwin
+* Fix possible crash when using longjmp and MinGW's gcc 4.6
+* Add topology calls: libusb_get_port_number(), libusb_get_parent() & libusb_get_port_path()
+* Add toggleable debug, using libusb_set_debug() or the LIBUSB_DEBUG environment variable
+* Define log levels in libusb.h and set timestamp origin to first libusb_init() call
+* All logging is now sent to to stderr (info was sent to stdout previously)
+* Update log messages severity and avoid polluting log output on OS-X
+* Add HID driver support on Windows
+* Enable interchangeability of MSVC and MinGW DLLs
+* Additional bug fixes and improvements
+
+2012-05-08: v1.0.11
+* Revert removal of critical Windows event handling that was introduced in 1.0.10
+* Fix a possible deadlock in Windows when submitting transfers
+* Add timestamped logging
+* Add NetBSD support (experimental) and BSD libusb_get_device_speed() data
+* Add bootstrap.sh alongside autogen.sh (bootstrap.sh doesn't invoke configure)
+* Search for device nodes in /dev for Android support
+* Other bug fixes
+
+2012-04-17: v1.0.10
+* Public release
+* Add libusb_get_version
+* Add Visual Studio 2010 project files
+* Some Windows code cleanup

+APPENDIX A - How to maintain code compatibility with versions of libusb and
+libusbx that use MaxPower:
+
+If you must to maintain compatibility with versions of the library that aren't
+using the bMaxPower attribute in struct libusb_config_descriptor, the 
+recommended way is to use the new LIBUSBX_API_VERSION macro with an #ifdef.
+For instance, if your code was written as follows:
+
+  if (dev->config[0].MaxPower < 250)
+
+Then you should modify it to have:
+
+#if defined(LIBUSBX_API_VERSION) && (LIBUSBX_API_VERSION >= 0x01000100)
+  if (dev->config[0].bMaxPower < 250)
+#else
+  if (dev->config[0].MaxPower < 250)
+#endif
