 -------------------------------------
 
 
+v0.5.3 (2014-11-21)
+
+* Support filenames of uppercase JPEG, JPG, PNG and GIF, as proposed in #37.
+* Changing `CImage::output()` as proposed in #37.
+* Adding security check that image filename is always below the path `image_path` as specified in `img_config.php` #37.
+* Adding configuration item in `img_config.php` for setting valid characters in image filename.
+* Moving `webroot/test*` into directory `webroot/test`.
+* `webroot/check_system.php` now outputs if extension for exif is loaded.
+* Broke API when `initDimensions()` split into two methods, new `initDimensions()` and `loadImageDetails()`.
+* Added `autoRotate,`aro` to auto rotate image based on EXIF information.
+* Added `bgColor,`bgc` to use as backgroundcolor when needing a filler color, for example rotate 45.
+* Added `rotateBefore,`rb` to rotate image a certain angle before processing.
+* Added `rotateAfter,`ra` to rotate image a certain angle after processing.
+* Cleaned up code formatting, removed trailing spaces.
+* Removed @ from opening images, better to display correct warning when failing #34, but put it back again.
+* Setting gd.jpeg_ignore_warning to true as default #34.
+* `webroot/check_system.php` now outputs version of PHP and GD.
+* #32 correctly send 404 header when serving an error message.
+* Trying to verify issue #29, but can not.
+* Adding structure for testprograms together with, use `webroot/test_issue29.php` as sample.
+* Improving code formatting.
+* Moving parts of verbose output from img.php to CImage.php.
+
+
 v0.5.2 (2014-04-01)
 
 * Correcting issue #26 providing error message when not using postprocessing.
