*) applies to 0.9.6a (/0.9.6b) and 0.9.7
+) applies to 0.9.7 only
+ +) Add a general user interface API. This is designed to replace things
+ like des_read_password and friends (backward compatibility functions
+ using this new API are provided). The purpose is to remove prompting
+ functions from the DES code section as well as provide for prompting
+ through dialog boxes in a window system and the like.

+ *) In versions up to 0.9.6, RAND_file_name() resorted to file ".rnd"
+ in the current directory if neither $RANDFILE nor $HOME was set.
+ RAND_file_name() in 0.9.6a returned NULL in this case. This has
+ caused some confusion to Windows users who haven't defined $HOME.
+ Thus RAND_file_name() is changed again: e_os.h can define a
+ DEFAULT_HOME, which will be used if $HOME is not set.
+ For Windows, we use "C:"; on other platforms, we still require
+ environment variables.
+
+) Add "ex_data" support to ENGINE so implementations can add state at a
per-structure level rather than having to store it globally.
