New releases should not mask already working functionality in old releases .
If it does it can cause surprise .

The server is the same in both cases .The libcurl versions are different

Please say if this is what you meant.
Since in 1st case it is a lower version of libcurl(7.15.1) it ignored
ftp-ssl and proceeded with normal ftp . But in 2nd case it is a higher
version which proceeds only if ftp-ssl otherwise bails out since it couldn't
use ftp-ssl. Hence you meant this was an intended change in the new version.
 Thanks in advance.

Modified behaviour between two versions should not surprise anyone. What
would
the purpose of doing new releases be otherwise?

Read the protocol dumps, they show it quite clearly.

See? This server refuses to do ftp-ssl when asked for it and libcurl bails
out
since it couldn't use the requested ftp-ssl level.

This failed to use ftp-ssl but silently ignored that and proceeded with
normal
ftp.
