+- ChangeLog O-3000 Host Driver
+-------------------------------------------------------------------------------
+
+Version 2.0.2
+ 2018-04-11-PR
+ * Function handle_transfer() rewritten:
+ The image frame synchronization was a bit hacky. Image frames were passed only to the
+ overlaying application after the next image frame has been received. But when receiving a single
+ snapshot, there won't follow an image. This causes a delay of one image until the application
+ receives it. Now the function passes images to the application after a image is
+ received completely without checking the preamble of the following image.
+ * Bug race condition at o3000_init() function:
+ Accessing the session table for getting next free session and allocation session structure
+ must be atomic.
+ * New function o3000_get_num_cam() added:
+ This function returns the number of connected O-3000 cameras to the system.
+ * New loglevel O3000_LOG_VERBOSE added:
+ This loglevel will set the libusb to debugging mode and is very useful for debugging purposes.
+
+Version 2.0.1
+ 2015-08-11 -PR
+ * Bugfix in function handle_transfer(): A negative byte offset was calculated when the resolution
+ has changed during wrap-around. A SEGFAULT occured.
+ * Fields added to image header and image header version update to 4:
+ - data rate in bytes/seconds
+ - frames per seconds
+ - field-of-view added used by lense distortion algorithm
+ * Short USB bulk transfers are supported now by the driver. Therefore the resolution
+ doesn't have to be a multiple of 512 bytes anymore and binning is done correctly.
+ There are following restrictions about image resolution settings:
+ - Window size must start with an even pixel coordinate (see examples below)
+ - Minimum image resolution is 640x480.
+ - Binning is allowed at full-screen only (1280x960)
+ E. g. valid window: X = 110 to 1111, Y = 32 to 917
+ E. g. invalid window: X = 111 to 1111, Y = 33 to 917 --> coordinate 111 and 33 are odd numbers
+
+ 2016-03-01
+ * Calling convention added for Win32 and Win64.
+
+Version 2.0.0 - 2015-02-16
+ * PR: Multi camera sessions capability. The host can scan the number of cameras and establish a connection to
+ each of them. Sending a XML message to the camera uses the synchronous API with OS dependet timeout handling.
+
+Version 1.0.0 - 2015-02-16
+ * PB: Inititial version
