The main change is that it now uses by default, grub4dos 0.4.6a (alpha version) instead of 0.4.5c (the stable version).
Changes from v1.61 are listed in the Version History page here. New changes since Beta A are:
- New grub4dos version 2015-01-16 as default (and new 0.4.5c version)
- Fix knoppix boot from non-contiguous ISO file in isoboot.g4b
- macpup sample .mnu file added for saving sessions on exit
- New .isomacpup file extension added
Grub4dos v0.4.6a has a few more features than 0.4.5c (can access Joliet ISOs, includes an internal USB 2.0 rd/wr driver and better debug/message control features).
E2B will still work OK with either version of grub4dos though.
Please let me know if you find any problems with this new version or with grub4dos 0.4.6a (i.e. if 0.4.5c works but 0.4.6a does not).
