I’m now “officially” maintaining WinBinder, so from now on you can get the latest version of WinBinder directly from Winbinder.org’s download page
Changes since 2010.10.01
Added in 2010.10.14
* Fixed bug with return values for wb_sys_dlg_open when using wbc_multiselect
* Made 3rd and 4th parameters of wb_send_message optional
Added in 2010.10.13
* Additional flag parameter for wb_sys_dlg_open that accepts the option WBC_MULTISELECT. If this is enabled, all selected files will be returned as an array.
