 Also, YafaRay, by default, ** will change the output folder/file name ** so the images are exported to a subfolder with the same name as the .blend file with suffix _render. This is for convenience and can be disabled, but if you leave the default it could cause you confusion especially when switching to other renderers.

+Changes from v3.0.0-beta to v3.0.1-beta:
+----------------------------------------
+* Important: Background IBL light sampling fix. This solves a long standing problem with incorrect background lighting accuracy and fireflies. (http://yafaray.org/node/752, http://yafaray.org/node/727, http://yafaray.org/node/566).
+
+* IBL clamp sampling parameter no longer needed thanks to the fix above, so it has been removed from the exporter.
+
+* Fix for crash when using yafaray-xml without specifying the type of badge to be used.
+
+* yafaray-xml: new "-ccd" "console-colors-disabled". If specified, disables the Console colors ANSI codes, useful for some 3rd party software that cannot handle ANSI codes well.
+
+* Light photon control: changed back control param names from "shoot_" to "with_" as originally for better backwards compatibility with 3rd party exporters
+
+* Render Passes: added "generic" external render passes for other Exporters and plugins other than Blender Exporter
+
+* Render passes: added new debug passes for diagnosing light estimation problems

 If you have any issues:
 
 * Check that you have copied the "yafaray_v3" folder into the correct Blender addons folder.
+* If you get the error message "file too short" in Linux systems, it could be caused by incorrect zip decompressing of links. Make sure you decompress the zip file in Linux so the links are correctly decompressed.
 * Check that you have downloaded the appropiate YafaRay build for your Operating System and Blender build (32/64 bit)
 * Check that you are using the official Blender build from www.blender.org and it's a version supported by YafaRay (see CHANGELOG)
 * In extreme cases (black renders, crashes, etc) remove all older YafaRay versions and other YafaRay derived forks, and try again.
