Based on feedback I've promoted 3.8.21beta1U to production, it can be found via links from http://smalltalkconsulting.com/squeak.html If someone can update ftp.squeak.org that would be helpful. Because of the following issues anyone using 3.8.20beta1U should upgrade. info.plist change: To turn on the mmap file mapping for the image loading, which can improve startup times alter the SqueakUseFileMappedMMAP setting to TRUE from the default value of false. Note the risk of turning this one appears to affect image saving where you experience: (a) lockups writing to images on NFS mounts (b) occasionally an image save to the local hard disk can fail. -- = = = ======================================================================== John M.
