+Version 0.1.2
+-------------
+
+2010-01-16
+
+New feature: photographers using RAW + JPEG mode now have the option to 
+synchronize sequence numbers for the matching pair of images. This option is
+useful if you use the RAW + JPEG feature on your camera and you use sequence
+numbers or letters in your image renaming. Enabling this option will cause the 
+program to detect matching pairs of RAW and JPEG images, and when they are 
+detected, the same sequence numbers and letters will be applied to both image
+names. Furthermore, sequences will be updated as if the images were one. For 
+example, if 200 RAW images and 200 matching JPEG images are downloaded, the 
+value of Downloads today will be incremented by 200, and not 400. The same goes 
+for the rest of the sequence values, including the Stored number sequence 
+number. Images are detected by comparing filename, as well as the exif value for
+the date and time the image was created (including subseconds when the camera 
+records this value). This option will take effect regardless of whether the RAW 
+and JPEG images are stored on different memory cards or the same memory card. 
+Furthermore, if they are stored on separate memory cards, you can download from 
+them simultaneously or one after the other. The only requirement is to download 
+the images in the same session--in other words, for the feature to work, use as 
+many memory cards as you need, but do not exit the program between downloads of 
+the matching sets of images.
+
+Increased maximum sequence number length to seven digits by user request.
+
+Fixed bug #503704: changes in values for downloads today and stored number not
+updated when changed via program preferences while a download is ready to begin.
+
+Fixed a rare startup bug, where the program could crash when starting a thread.
+
+Added Serbian translation by Milos Popovic. Updated Czech, Dutch, Finnish,
+French, German, Hungarian, Italian, Polish, Russian, Slovak, Spanish and 
+Swedish translations.
+
