Here's a suggestion that I hope will be easy for Robert to accept and helpful to others if he does.
Often when a new version of TC/MC is released, it comes with a note about files that have changed in the new release that might conflict with older versions in users' backups. I use grub to boot TC, so I update TC simply by replacing the file 'tinycore.gz' in my boot directory with the new one. (Of course I check that the new kernel matches the previous kernel, too.) When I boot the new version, the material in my backup overwrites the new and improved files just as the release announcement warns. Unfortunately, this makes it difficult to take advantage of the invitation to use the fresh ones. There are probably several ways to access the new files, but here's a simple idea that could beat them all. Could the updated files mentioned in the release announcement be made available for direct download? Maybe they could even be supplied as attachments to the announcement itself in the forums. This change in standard operating procedure shouldn't be too onerous: the developer has a copy of the files on a working new system, and the files involved are usually few in number and small in size.
Thank you Robert and Team TC for your ongoing work. I'm still loving it.
