An SSL connection to a server 687 with an unknown CA will now fail unless a verification callback is used. 688 - enable SSL session caching (performance improvement) 689 - support for wildcard server certs where commonName is "*.example.com". 690 - thanks to Tommi Komulainen for the contribution of code from mutt's 691 IMAP/SSL implementation under the LGPL, from which bits of this were derived. 692* Improved SSL client certificate support: 693 - far simpler interface, all done at ne_session.h level. 694 - supports PKCS#12 and PEM-encoded certificates. 695 - optional callback for only providing client when demanded by server. 696* Support for TLS upgrade is removed, since it isn't useful. 697* If NEON_SSL is defined, API extensions are available to: 698 - allow access to the SSL_CTX * to adjust session SSL options 699 - retrieve the server certificate (X509 *) 700* Decompress fixes: 701 - fix potential segfault in ne_decompress_destroy 702 - check the CRC of the deflated output (and fail if it doesn't match) 703 - fail appropriately on truncated responses, and trailing bytes in response. 704* Added ne_set_read_timeout to use configurable timeout on socket reads. 705* Malformed response headers will be ignored rather than failing the request. 706* ne_set_error takes printf-style vararg. 707* Fixes for ne_get_range and improve error handling. 708* Functions which append to an ne_buffer do not return a success value, 709 but they do use ne_realloc/ne_malloc under the hood now, so an OOM callback 710 will be used (with the usual caveats). 711* XML interface does not strip leading whitespace from cdata by default, 712 the NE_XML_STRIPWS flag is available to restore this feature if required. 713* Upgraded to libtool 1.4.2: 714 - should fix --enable-shared on Mac OS X 10.1 715* Test suite now contains over one hundred tests. 716 717Changes in release 0.18.5: 718* Removed old neon.dsp, neon.dsw. 719* Update Win32 build to add OpenSSL and zlib support (Branko �ibej). 720* Fix ne_compress.c to compile on Win32 (Branko �ibej). 721 722Changes in release 0.18.4: 723* Fixes for Content-Type parsing using ne_content_type_handler (Greg Stein) 724 - also now parses the charset parameter from header value. 725* Removed ne_concat() function, which didn't work and wasn't used. 726 727Changes in release 0.18.3: 728* Fix parsing lock timeout from server (Arun Garg). 729* Send Timeout headers in LOCK and refresh LOCK requests (Arun Garg). 730* Updated neon.mak and config.hw.in for Win32 build (patch from 731 Branko �ibej <brane@xbc.nu>). 732* Define XML_BYTE_ORDER for bundled expat build in support macro 733 NEON_XML_PARSER(). 734 735Changes in release 0.18.2: 736* Fix --with-neon=PATH in support macros. 737* Support DESTDIR in Makefile install targets (patch by 738 Pawel Golaszewski <blues@blysk.ds.pg.gda.pl>). 739* Portability fixes: 740 - fix configure check for time_t on some platforms (e.g Solaris 2.6). 741 - remove expect100_works bitfield in ne_session structure (thanks to 742 Yan Periard <yperiard@ems.net>). 743 744Changes in release 0.18.1: 745* Minor fix for authentication: "attempt" counter was not reset correctly 746 after authentication failed, so subsequent requests would not authenticate 747 correctly either. 748* API change: ne_session_destroy returns void (there was no error case). 749* Portability fixes (non-GCC compilers, 64-bit platforms, UnixWare 7) 750* Optimisations in string manipulation routines. 751* config.hw is included in the release tarball again. 752* Improvements in the autoconf support macros: 753 - check for neon-config in PATH if --with-neon is not given 754 - stop if --with-neon is used, and the check for external neon fails 755 - added NEON_WITHOUT_ACL to prevent build of ne_acl.o 756 757Changes in release 0.18.0: 758* API change: authentication callback is passed fixed-size username/password 759 buffers, and an 'attempt' counter. Authentication is retried *forever* 760 until either it succeeds, or the callback returns non-zero. 761* API clarifications: 762 - ne_propname may have a NULL nspace field, indicating the property has no 763 namespace. This holds for properties returned by the propfind interfaces. 764 - added NE_ELM_PROPS_UNUSED as the lowest element number which should 765 be used with handlers added to the XML parser returned by 766 ne_propfind_get_parser. 767* Fixes and cleanups of lock discovery interface. 768* Fix for short write handling in ne_get() (thanks to rado <dzusto@yahoo.com>). 769* Fix for XML namespace prefix handling where a prefix could be mapped to an 770 incorrect URI (e.g. in PROPFINDs against mod_dav with >10 namespaces used) 771* Add '--support <feature>' option to neon-config; the script exits with 772 success if given feature is supported. Known features are ssl, dav, zlib. 773* Support for SSL, DAV, zlib is exported by neon.m4 as shell variable 774 NEON_SUPPORTS_{SSL,DAV,ZLIB}={yes,no} for bundled and external builds. 775* `neon-config --cflags` won't include -I/usr/include for SSL build. 776* Fix to call progress callbacks while sending request bodies again. 777* Test changes: 778 - portability fixes, auth interface and progress tests. 779 780Changes in release 0.17.2: 781* Accept Status-Lines with no reason phrase (Jeremy Elson). 782* Fix handling of persistent connection timeout, and better error 783 handling if sending a request fails. 784* Fix crashes in locking code. 785* Return parse error on XML namespace prefix declaration with 786 an empty value.

(Johan Lindh). 956* Partial fix for timezone/date parsing problems. 957 958Changes in release 0.13.0: 959* Fix ne_strndup allocating one byte less than it should (Kai Sommerfeld) 960 - if you use uri_parse, this bug may have caused subtle memory corruption 961 in your application. 962* Revert API changes in 0.12: property values are not UTF-8 encoded/decoded 963 internally. (thanks to Greg Stein) 964* Add another optional argument to NEON_BUNDLED macros, actions to 965 be run if bundled build is *not* selected. 966* API change: added argument to http_add_hooks to register cleanup function 967 for the cookie. 968* Removed dav_lock_unregister in favour of automatic cleanup when session 969 is destroyed. 970* Fixed leaks in redirect code (Kai Sommerfeld). 971* Fixed crashes in hip_xml_destroy (Kai Sommerfeld). 972* Redirects to a different hostname/port/scheme are never followed: the request 973 will fail with HTTP_REDIRECT instead.

Socket-level status callbacks removed, progress 993 callbacks made per-socket. 994* Supports new expat (Sam TH <sam@uchicago.edu>) 995* Supports libxml2 (in preference to libxml1). 996* API change: added namespace protection to base64 and dates functions: 997 all have ne_ prefix now. 998* Fixed ranged GETs where a specific range is requested (Johan Lindh 999 <johan@linkdata.se>). 1000* Limit number of response header fields to 100. 1001* Allow requests for the '*' URI even if a proxy server is in use. 1002* libxml: Get useful error messages for parse errors. 1003 1004Changes in release 0.12.0: 1005* Portability fixes to http_request.c and http_auth.c. 1006 - fixes digest auth on big-endian architectures. 1007* Fix warnings from stray tokens after #endif's in uri.h and string_utils.h. 1008* Add C++ inclusion safety to http_redirect.h (Kai Sommerfeld 1009 <kai.sommerfeld@germany.sun.com>). 1010* Make redirects to a different host work (Kai Sommerfeld). 1011* Fix reading response bodies when non-chunked and no Content-Length 1012 (Kai Sommerfeld). 1013* API change: 'http_add_hooks takes a 'const' request object. 1014* Fixed memory leaks in session hooks (thanks to Kai Sommerfeld). 1015* Fix passing NULL props argument to dav_simple_propfind, to support 1016 allprop requests. 1017**** MAJOR INTERFACE CHANGE **** 1018 - URIs passed to http_request_create() are NOT escaped by neon. You 1019 MUST do this yourself to remain HTTP compliant, using e.g. 1020 uri_abspath_escape. (Kai Sommerfeld) 1021* Added --disable-webdav flag to configure, to disable DAV support in 1022 the library. This allows building neon without an XML parser. 1023* Corresponding NEON_WITHOUT_WEBDAV macro for use in bundled builds. 1024* Fix Makefile dependancies. 1025* A bundled neon directory builds or doesn't build automatically 1026 (i.e. you recurse into it unconditionally). 1027* API clarification: 1028 - dav_propset_status may return NULL if the server does not return 1029 a response for the given property (issue is open for debate). 1030* API change up for debate: 1031 - Property values to dav_proppatch are UTF-8 encoded internally. 1032 - Property values in dav_propfind_* are UTF-8 decoded internally. 1033* API additions: ne_realloc, ne_utf8_encode. 1034 1035Changes in release 0.11.0: 1036* Added SSL client certificate support with 'sock_set_client_cert'. 1037 - Supports certs in PEM-encoded files. 1038 - Specify a callback for prompting the user for the password with 1039 sock_set_key_prompt. 1040* Added 'ne_oom_callback', to register a callback which is used if 1041 malloc() returns NULL. (Mike Rosellini <m@icopyright.com>) 1042* Register appropriate callback with libxml to handle <![CDATA blocks 1043 as normal character data (fixes PROPFINDs against sharemation.com). 1044* Added 'NEON_REQUIRE' macro to declare that you require a neon library 1045 of a given minimum version, e.g. NEON_REQUIRE(0,10) means "I need 1046 neon 0.11 or later". The _BUNDLED macros will fall back on the bundled 1047 copy if an external library is found which is not of a new enough version. 1048* Added neon_version_minimum() function call for run-time version detection. 1049* neon_config.h has been removed. 1050* Use closesocket() to close sockets on Win32 (Markus Fleck <fleck@isoc.de>). 1051 1052Changes in release 0.10.1: 1053* Default expect-100 to OFF. 1054 1055Changes in release 0.10.0: 1056* hip_xml API changes: 1057 - The search for a handler for a new child element begins at the 1058 handler of the parent element, and carries on up the stack. 1059 (previously, it always started from the base of the stack) 1060 - Documentation written: doc/parsing-xml.txt 1061* Remove memory leaks and tidy debugging output in new properties code. 1062* API changes to DAV locking interface: 1063 - New function: dav_lock_copy to copy a lock object. 1064 - Re-ordered arguments to callback of dav_lock_discover, and made the 1065 lock object passed back const. 1066 - Fix leaks and crashes due to vague interface definitions. 1067* API change to dav_propfind_set_complex: use a callback to return the 1068 'private' structure. 1069* NEON_NORMAL_BUILD and NEON_LIBTOOL_BUILD macros defined for setting 1070 up neon's Makefile in a bundled build: see macros/neon.m4. 1071* NEON_VPATH_BUNDLED macro added which takes separate srcdir and 1072 builddir arguments for supporting VPATH builds (thanks to Peter Moulder 1073 <pjm@bofh.asn.au>). 1074* Added optional final argument to NEON_(VPATH_)BUNDLED, which gives 1075 a set of actions to be run if the bundled build is chosen. 1076* NEON_SSL checks for OpenSSL in /usr too. 1077* API change: when using http_session_decide_proxy, it MUST be called 1078 before using http_session_server to prevent the DNS lookup on the origin 1079 server being optimised out. The real scheme in use is passed to the 1080 callback now. 1081* New function, dav_207_ignore_unknown, to ignore any unknown XML fragments 1082 in the 207 response. Used by properties layer. 1083 1084Changes in release 0.9.2: 1085* Fix using both dav_propfind_set_complex and dav_propfind_set_flat with the 1086 same propfind_handler. 1087 1088Changes in release 0.9.1: 1089* dav_propfind interface 1090 - Guarantee that the 'private' structure will be initialized to zero on 1091 creation. 1092 - Make it the *callers* responsibility to free() the private structure. 1093* Fix a few arguments/variables which mirrored globally declared symbols. 1094 1095Changes in release 0.9.0: 1096* Removed old dav_propfind_* interface, replaced with a better, more 1097 powerful, and easier to use interface: 1098 - 'dav_simple_propfind' interface for just fetching "flat" (byte-string) 1099 properties. 1100 - 'dav_propfind_*' interface for fetching flat and/or "complex" (structured 1101 XML) properties. 1102 - Lets you retrieve the 'status' information, to see what happened if 1103 fetching the property failed (e.g 404 Not Found). 1104* Fixes to doc/using-neon.txt (thanks to Greg Stein). 1105* Allow building when srcdir != builddir (Mo DeJong <mdejong@cygnus.com>) 1106 1107Changes in release 0.8.1: 1108* Fix segfault in PROPFIND code. 1109 1110Changes in release 0.8.0: 1111* Fix for using COPY/MOVE over SSL (thanks to David Sloat). 1112* Fix for using a proxy server and SSL. 1113* Added 'http_get_scheme' API call. 1114* Added 'http_redirect.h' to list of installed headers (thanks to everyone ;). 1115* Changes for building on Windows (Peter Boos <PediB@colorfullife.com>) 1116* Fixes for building on BeOS (Sam TH <sam@uchicago.edu> and David Reid 1117 <dreid@jetnet.co.uk>). 1118* Add buffering to socket code for pre-BONE BeOS systems (David Reid). 1119* Interface changes for hip_xml: 1120 - Renamed hip_xml_add_(mixed_)handler to hip_xml_push_(mixed_)handler 1121 - Documentation updates. 1122 - Added HIP_ELM_UNUSED for lowest element id which should be used. 1123*** MAJOR INTERFACE CHANGE *** 1124 - Removed 'http_status *' pointer from http_request_dispatch. 1125 - Added http_get_status(req) to retrieve the response-status information 1126 instead. You don't have to declare an http_status object yourself now. 1127* Similarly, added DAV_ELM_207_UNUSED for lowest element id which should 1128 be used by users of dav_207_* code (incl. use of dav_propfind_* 1129 code). 1130* New NEON_* autoconf macro interface: 1131 - Use NEON_BUNDLED if sources are bundled, otherwise NEON_LIBRARY. 1132 - The NEON_XML_PARSER macro is NOT called automatically. You must 1133 call this yourself if using NEON_BUNDLED; see doc/using-neon.txt 1134 for details. 1135* Fix use of 'socket' in nsocket.h function prototypes (Greg Stein). 1136* Remove extra backslash at line 69 of src/Makefile.incl (Dirk Bergstrom). 1137* Examples directory is now a separate package. 1138 1139Changes in release 0.7.7: 1140* Another fix for linking against a libtool-built expat (Greg Stein). 1141 1142Changes in release 0.7.6: 1143* Better check for closed SSL connection after doing SSL_peek.
