After far too long with a name that wasn't really descriptive about all its current features, for version 4.0 I've finally renamed the plugin to "simpleuploads"
That means that when you upgrade this very first time you might experience a few hickups, but it should be easy if you pay a little attention.
Also I must recognize that there's a lot of new code (v4 means far more than the rename of the plugin), and that code might have unexpected bugs, so if you're unsure you can wait a few days/weeks to check that I don't publish a new version to polish this version
First of all: backup your setup :-)
Now delete the imagepaste folder from the plugins folder and place the new simpleuploads instead
Just like when you first installed it open your config.js, and in the config.extraPlugins replace imagepaste with simpleuploads
If you didn't apply any extra customizations then you're done!. Clear the cache and reload the editor
But you might have used some of the configuration options that the plugin provides, in that case you have to update that code also
The events have been renamed from imagepaste.* to simpleuploads.*, that's easy to fix
The configuration options are also mostly easy, replace config.simpleuploads_* with config.simpleuploads_*, there's only two exceptions: the CSS clases for dragover, I've renamed the "hover" part to just "over", so they become:
imagepaste_editorhover -> simpleuploads_editorover
imagepaste_containerhover -> simpleuploads_containerover
That should take care of almost everything, there's one last item: you might have used the tmp class in your CSS to style the uploads, in that case you must change .ImagePasteTmpWrapper with .SimpleUploadsTmpWrapper
I might provide updated info in my blog
