- This copy has many security additions added to it. Loader code
- and data is encrypted along with the regular encrypted program code.
- Earlier versions have had a few vulnerable spots in them but are for
- the most part safe. Both the COM and EXE loaders have been revamped and
- there is more than one specific model for each loader. A few changes were
- made so that the files will load a little faster also. Also, a few cosmetic
- changes have been made to the actual program, but for the most part, the
- changes were focused upon the loader's speed and security. This version
- is much improved over previous versions partially due to letters and
- comments from a few hackers and programmers. Weaknesses (particularily in
- the COM files) were pointed out and greatly improved upon, so thanks
- to everybody who wrote about Protect! EXE/COM!!! On the side note, you
- may now have spaces in your password (you don't need underscores anymore)!

- Protect! EXE/COM 1.1
-
- 4/26/93
-
- This copy has been released to fix a bug that occurs on some
- earlier XT computers when run. There is one instruction in the header
- that is not recognized by the "genuine" 8088's and 8086's, but is only
- recognized by the NEC V20, NEC V30, as well as the 286 and above. Since
- the XT that I tested this on used the NEC V20 (8088 compatible chip with
- a few enhancements) instead of the true 8088, it did not catch that error
- as a true 8088 would have. Thanks to an alert user in Virginia, the error
- was quickly caught and remedied (it took less than a half hour to fix),
- and now Protect! EXE/COM v.1.1 will work on all XT-class computers.
