You can get these latest releases from Christian's github.
If you've been using the IAP to update firmware then you can do the complete update without USB, bossac or removing the CF card! Here's how, it's as easy as 1, 2, 3:
From Settings->General in DWC:
- upload the DWC zip file. Note, Mac OS X automatically unzips after downloading so you may have to recompress the root folder.
- upload the IAP
- upload RRF
There are a few feature differences between ch and dc42 firmwares (comparing the latest versions).
- ch has G-code interleaving, which means you can run G-codes from any input source at the same time like PanelDue, Serial USB, code quay, file and macro. There is a G-codequeue that insures codes like M106 are executed in time. These features are useful for cooling bridges, etc.
- the current ch has the most recent fixes for the disconnect issues that affected many users.
- otherwise, the overall functionality is basically the same.
Note that the latest dc42 firmware also supports the IAP and DWC 1.11
