Changes from Version 14.5 to Version 15

Version 15 of this C API has changed from version 14.5 as follows:

• LEADTOOLS Version 15 now supports both ANSI and UNICODE development in the same libraries.

• LEADTOOLS now supports development for x64 platforms.

Note: x64 Platforms are not supported in the current version of LEADTOOLS TWAIN due to a lack of availability of a 64-bit version of TWAIN.  As soon as TWAIN releases 64-bit support, LEADTOOLS will also support x64 TWAIN.

• LEADTOOLS now supports specifying the version of toolkit that you are using. You should define LTVXX_CONFIG in your project, where "*" is the version you are using, for example: LTV15_CONFIG.

• LEADTOOLS now supports Unicode.

L_TwainFastAcquire has been replaced.
