Only the GUI is new, so if you already have mp3gain installed, just download the "GUI only" file, un-zip it, and replace your current copy of that file with the new one.
New feature: Save/Load Analysis results! Pretty self-explanatory, I think.
Right now it's very picky: if you move your files to a different folder after saving the analysis results, mp3gain will not be able to find them again... unless you edit the .csv file yourself, which really isn't too hard.
Oh, and the "install" versions broke during the upload again :mad:
But after the fiasco last time, I put a workaround in place: there's now a download that installs just the support files (Microsoft VB run-time files and stuff). So if you need a full installation, you can download the "EXE only" and the "VB stuff" downloads. Run the installation program from the VB package, and then manually un-zip the EXE files into the MP3Gain folder that was created by the installer.
