AiR-BOOT v1.07 -- As released with eCS v2.1. [2011-05-06]
Signature-date: 2006-03-13. (incorrect)
Trunk contains buildable v1.07 version as distributed with eCS v2.1.
Directory 'tags' contains v1.06 & v1.07 reference versions
built for all languages. Note that language ID for 'Dutch' changed
from 'DT' to 'NL' in v1.07 and that the v1.06 reference version also
uses 'NL' for 'Dutch'.
Also note that helper programs like the installer and setaboot are
are only modified for the OS/2 versions in v1.07.
The signature-date for v1.07 incorrectly states the same
date as for v1.06. The signature-version is correct.
Removed other binaries. (cd-rom images, old releases, etc.)
The tags serve as reference versions:

• v1.06: rebuilt from source. (tags/v1.06r)
• v1.07: built as released with eCS v2.1. (tags/v1.07r)
