New Features in s3270 3.3

s3270 3.3 is the future development line for s3270. It is functionally equivalent to s3270 3.2.20, with the addition of SSL (Secure Sockets Layer) support and DBCS (Double Byte Character Set) support for East Asian languages -- Chinese, Japanese and Korean.

The DBCS work required a significant change in the internal workings of s3270. For those familiar with the source code, the change was to store EBCDIC codes internally, and to dispense with the confusing CG-code representation of the 3270 display. This required changing all of the logic that manipulates field attributes, as well as the logic that translates the host output, keyboard input, and X11 display output.

A few eggs were broken in that process:

And other bugs may yet lurk.

However, once s3270 3.3 is stable enough and the broken features have been corrected, it will replace s3270 3.2.
