grub4dos - good news, very good news and not so good news!

YaYa has fixed two bugs in grub4dos 0.4.6a
  1. Issue #122 - Replacing strings in a file using cat --locate=xxx --replace=yyy sometimes didn't work
  2. Issue #119 - grub4dos crashes when it access certain partitions (this is the “\_ISO\e2b\grub\E2B.cfg is MISSING!” issue)
Bug #122 has a workaround and this has been added into E2B v1.82 so that we can use older versions of grub4dos if we need to (useful for testing different versions, etc.). The bug was only found due to the new SDI_CHOCO feature in v1.82 and so did not affect previous versions of E2B.

Bug #119 is great news. Many people have helped in investigating this bug but a special thanks to Norbert who spent a lot of time to prepare a Virtual Machine in VBox which allowed the developer (YaYa) to see the problem and enabled him to fix it!

The not so good news, is that I discovered a new bug to do with certain types (joliet?) of XP ISOs crashing when accessed (e.g. using a cat command on a file inside the ISO). The bug report is Issue #123 and affects grub4dos 0.4.6a versions after 2016-04-10 (so does affect E2B v1.81 which used 2016-07-04 and E2B v1.80 which used 2016-04-26, but not E2B v1.79 which used 2016-03-26). A genuine MS XP3 ISO does not seem to be affected though and it only seems to happen with some ISOs on some systems (TBD). Hopefully, YaYa can find the problem and fix it. Then we will have a new version of grub4dos with all the major outstanding bugs fixed.

2016-08-04 - YaYa has fixed the bug. Next version should have all fixes!
