Also deprecates all httpMD5* functions.
- cgi-bin/var.c: Use cupsHashData to compute SID hash.
- cups/auth.c: Rewrite WWW-Authenticate parser to support multiple auth schemes
and the new RFC 7616 version of HTTP Digest.
- cups/cups.h: Add cupsHashString function to get a hex version of a hash.
- cups/hash.c: Add MD5 support.
- cups/http.c: Track WWW-Authenticate in a long string, concatenate new set
values.
- cups/http.h: Deprecate httpMD5* and recommend cupsDoAuth and cupsHash*.
- cups/http-private.h: Pull MD5 stuff, nonce_count is unsigned, track
WWW-Authenticate header as a potentially long string.
- cups/http-support.c: Use cupsHashData to compute UUID hash.
- cups/md5.c: Comment everything out if we have an OS-supplied MD5 hash
function.
- cups/md5passwd.c: Use cupsHash* functions.
- cups/tls-*.c: Use cupsHash* functions.
- cups/versioning.h: Add CUPS_API_2_3 definition.
- scheduler/client.c: Update WWW-Authenticate header to include AuthRef,
Local, and PeerCred schemes with parameters as needed.
-CHANGES - 2.3b1 - 2017-11-03
+CHANGES - 2.3b1 - 2017-11-06
============================
- Documentation updates (Issue #4580)
- The `lpstat` command now reports when new jobs are being held (Issue #4761)
+- The CUPS library now supports the latest HTTP Digest authentication
+ specification including support for SHA-256 (Issue #4862)
- The scheduler now supports the "printer-id" attribute (Issue #4868)
- No longer support backslash, question mark, or quotes in printer names
(Issue #4966)
