I've just released firmware 057y-dc42 to fix a couple of issues that were annoying me. The first is to support long filenames. This version displays long filenames already on the SD card correctly; however it needs a patch to Matt's web interface if you want to to upload new files preserving the long filenames (otherwise filenames get truncated to 8.3 format during upload). The patch is to change line 477 in reprap.js to "gFilename = fName;" without the quotes - and of course you need to be running a local web server in order to use the patched version.
The second patch is to fix the behaviour of the M201 command, which sets the axis accelerations. Previously, if you set X and Y accelerations but not Z, it would set the Z acceleration to a stupidly low value. Now, for any axes you don't specify in the command, it leaves the accelerations alone.
