Changes in release 0.21.2:
* Fix 'make install' for VPATH builds.
* Use $(mandir) for installing man pages (Rodney Dawes).
* Follow some simple (yet illegal) relativeURI redirects.
* Always build ne_compress.obj in Win32 build (Branko ╚ibej).
* Fix decompression logic bug (Justin Erenkrantz <jerenkrantz@apache.org>)
(could give a decompress failure for particular responses)
* Fix ne_proppatch() to submit lock tokens for available locks.
* More optimisation of ne_sock_readline.

Changes in release 0.21.1:
* Don't include default SSL port in Host request header, which can
help interoperability with misbehaving servers (thanks to Rodney Dawes
* Don't give a "truncated response" error from ne_decompress_destroy if
the acceptance function returns non-zero.
* Fix for Win32 build (Sander Striker <striker@apache.org>).
* Fix for cookie name/value being free()d (thanks to Dan Mullen).
* Optimisation of ne_sock_readline.

Changes in release 0.21.0:
* Socket layer implements read buffering; efficiency and performance
improvement. Based on work by Jeff Johnson <jbj@redhat.com>
* Cleanup of socket interface:
- renamed everything, s/sock_/ne_sock_/, s/SOCK_/NE_SOCK_/
- removed unused and inappropriate interfaces.
- renaming done by Olof Oberg <mill@pedgr571.sn.umu.se>
- see src/ChangeLog for the gory details.
* Fix typoed 'ne_destroy_fn' typedef (Olof Oberg).
* Support OpenSSL/ENGINE branch.
* Bogus ne_utf8_encode/decode functions removed.
* ne_base64() moved to ne_string.[ch].
* ne_token drops 'quotes' parameter; ne_qtoken added.
* ne_buffer_create_sized renamed to ne_buffer_ncreate.
* ne_xml_get_attr takes extra arguments and can resolve namespaces.
* ne_accept_response function type takes const ne_status pointer.
* Drop support for automatically following redirects:
- ne_redirect_register just takes a session pointer
- ne_redirect_location returns an ne_uri pointer
* configure changes: --with-ssl and --with-socks no longer take a directory
argument.  To use SOCKS or SSL libraries/headers in non-system locations,
use ./configure CPPFLAGS=-I/... LDFLAGS=-L/...
* Reference documentation included for most of ne_alloc.h and ne_string.h,
and parts of ne_session.h and ne_request.h.
- see installed man pages, HTML documentation.

Changes in release 0.20.0:
* Major changes to DAV lock handling interface (ne_locks.h):
- struct ne_lock uses a full URI structure to identify locked resource
- ne_lock() requires that owner/token fields are malloc-allocated (or NULL)
on entry
- introduce a "lock store" type, ne_lock_store, to replace the lock session;
accessor functions all renamed to ne_lockstore_*.
- ne_lock_iterate replaced with a first/next "cursor"-style interface
- If: headers use an absoluteURI (RFC2518 compliance fix).
- fix for handling shared locks on DAV servers which return many active locks
in the LOCK response (thanks to Keith Wannamaker)
* Moved URI/path manipulation functions under ne_* namespace (ne_uri.h):
- path handling functions renamed to ne_path_*
- URI structure handling to ne_uri_*; struct uri becomes ne_uri.
- ne_uri_parse doesn't take a 'defaults' parameter any more
- if URI port is unspecified, ne_uri_parse sets port to 0 not -1.
- added ne_uri_unparse and ne_uri_defaultport functions.
* New 'ne_fill_server_uri' function to initialize a URI structure with
the server details for a given session (useful with locks interface).
* ne_decompress_{reader,destroy} are defined as passthrough-functions
if zlib support is not enabled.
* API change: ne_ssl_provide_fn returns void not int.
* Added NE_SSL_FAILMASK for verify failure sanity check.
* Removed return codes NE_SERVERAUTH and and NE_AUTHPROXY; correct
documentation, NE_PROXYAUTH is given for proxy auth failure.
* Require zlib >= 1.1.4 to avoid possible vulnerability in earlier versions.
See http://www.gzip.org/zlib/advisory-2002-03-11.txt for more details.
(version check can be skipped by passing --with-force-zlib to configure)
* New 'ne_ssl_readable_dname' function to create a human-readable string
from an X509 distinguished name.
* Fix support for newer versions of libxml2 (thanks to Jon Trowbridge
* Fix corruption of reason_phrase in status object returned by
* More lenient handling of whitespace in response headers.
* ne_content_type_handler will give a charset of "ISO-8859-1" if no charset
parameter is specified for a text/* media type (as per RFC2616).
* Miscellaneous cleanups and fixes (Jeff Johnson <jbj@redhat.com>).

Changes in release 0.19.4:

* Fix some error messages in new SSL code.

Changes in release 0.19.0:
* Major API change: ne_session_create now takes (scheme, hostname, port)
arguments: a session is clarified to be "a group of requests to a
certain server".
- removal of ne_session_server, ne_set_secure, and ne_set_proxy_decider
- ne_session_proxy returns void.
- DNS lookups are delayed until request dispatch time.
* Significant improvements to TLS/SSL support:
- SSL is enabled if scheme passed to ne_session_create is "https"
- new interfaces to load CA certs and to load SSL library's bundled CA certs
- add server cert verification callback.  An SSL connection to a server
with an unknown CA will now fail unless a verification callback is used.
- enable SSL session caching (performance improvement)
- support for wildcard server certs where commonName is "*.example.com".
- thanks to Tommi Komulainen for the contribution of code from mutt's
IMAP/SSL implementation under the LGPL, from which bits of this were derived.
* Improved SSL client certificate support:
- far simpler interface, all done at ne_session.h level.
- supports PKCS#12 and PEM-encoded certificates.
- optional callback for only providing client when demanded by server.
* Support for TLS upgrade is removed, since it isn't useful.
* If NEON_SSL is defined, API extensions are available to:
- allow access to the SSL_CTX * to adjust session SSL options
- retrieve the server certificate (X509 *)
* Decompress fixes:
- fix potential segfault in ne_decompress_destroy
- check the CRC of the deflated output (and fail if it doesn't match)
- fail appropriately on truncated responses, and trailing bytes in response.
* Added ne_set_read_timeout to use configurable timeout on socket reads.
* Malformed response headers will be ignored rather than failing the request.
* ne_set_error takes printf-style vararg.
* Fixes for ne_get_range and improve error handling.
* Functions which append to an ne_buffer do not return a success value,
but they do use ne_realloc/ne_malloc under the hood now, so an OOM callback
will be used (with the usual caveats).
* XML interface does not strip leading whitespace from cdata by default,
the NE_XML_STRIPWS flag is available to restore this feature if required.
* Upgraded to libtool 1.4.2:
- should fix --enable-shared on Mac OS X 10.1
* Test suite now contains over one hundred tests.

- remove expect100_works bitfield in ne_session structure (thanks to
Yan Periard <yperiard@ems.net>).

Changes in release 0.18.1:
* Minor fix for authentication: "attempt" counter was not reset correctly
after authentication failed, so subsequent requests would not authenticate
correctly either.
* API change: ne_session_destroy returns void (there was no error case).
* Portability fixes (non-GCC compilers, 64-bit platforms, UnixWare 7)
* Optimisations in string manipulation routines.
* config.hw is included in the release tarball again.
* Improvements in the autoconf support macros:
- check for neon-config in PATH if --with-neon is not given
- stop if --with-neon is used, and the check for external neon fails
- added NEON_WITHOUT_ACL to prevent build of ne_acl.o

Changes in release 0.18.0:
* API change: authentication callback is passed fixed-size username/password
buffers, and an 'attempt' counter.  Authentication is retried *forever*
until either it succeeds, or the callback returns non-zero.
* API clarifications:
- ne_propname may have a NULL nspace field, indicating the property has no
namespace.  This holds for properties returned by the propfind interfaces.
- added NE_ELM_PROPS_UNUSED as the lowest element number which should
be used with handlers added to the XML parser returned by
* Fixes and cleanups of lock discovery interface.
* Fix for short write handling in ne_get() (thanks to rado <dzusto@yahoo.com>).
* Fix for XML namespace prefix handling where a prefix could be mapped to an
incorrect URI (e.g. in PROPFINDs against mod_dav with >10 namespaces used)
* Add '--support <feature>' option to neon-config; the script exits with
success if given feature is supported. Known features are ssl, dav, zlib.
* Support for SSL, DAV, zlib is exported by neon.m4 as shell variable
NEON_SUPPORTS_{SSL,DAV,ZLIB}={yes,no} for bundled and external builds.
* `neon-config --cflags` won't include -I/usr/include for SSL build.

- prettify output; imitate Perl test suite output.
- add tests for interim 1xx responses, persistent connections, more
unbounded operations.

Changes in release 0.17.0:
* Add support for decoding gzip Content-Encoding: see ne_compress.h.

  is destroyed.
* Fixed leaks in redirect code (Kai Sommerfeld).
* Fixed crashes in hip_xml_destroy (Kai Sommerfeld).
* Redirects to a different hostname/port/scheme are never followed: the request

   MUST do this yourself to remain HTTP compliant, using e.g.
   uri_abspath_escape. (Kai Sommerfeld)
* Added --disable-webdav flag to configure, to disable DAV support in
  the library.  This allows building neon without an XML parser.
* Corresponding NEON_WITHOUT_WEBDAV macro for use in bundled builds.
* Fix Makefile dependancies.
* A bundled neon directory builds or doesn't build automatically
  (i.e. you recurse into it unconditionally).

   a response for the given property (issue is open for debate).
* API change up for debate:
- Property values to dav_proppatch are UTF-8 encoded internally.
- Property values in dav_propfind_* are UTF-8 decoded internally.
* API additions: ne_realloc, ne_utf8_encode.

Changes in release 0.11.0:
* Added SSL client certificate support with 'sock_set_client_cert'.
- Supports certs in PEM-encoded files.
- Specify a callback for prompting the user for the password with

* Register appropriate callback with libxml to handle <![CDATA blocks
  as normal character data (fixes PROPFINDs against sharemation.com).
* Added 'NEON_REQUIRE' macro to declare that you require a neon library
  of a given minimum version, e.g.  NEON_REQUIRE(0,10) means "I need
  neon 0.11 or later".  The _BUNDLED macros will fall back on the bundled
  copy if an external library is found which is not of a new enough version.
* Added neon_version_minimum() function call for run-time version detection.
* neon_config.h has been removed.
* Use closesocket() to close sockets on Win32 (Markus Fleck <fleck@isoc.de>).

Changes in release 0.10.1:
* Default expect-100 to OFF.

Changes in release 0.10.0:
* hip_xml API changes:
- The search for a handler for a new child element begins at the
   handler of the parent element, and carries on up the stack.
   (previously, it always started from the base of the stack)
- Documentation written: doc/parsing-xml.txt
* Remove memory leaks and tidy debugging output in new properties code.
* API changes to DAV locking interface:
- New function: dav_lock_copy to copy a lock object.
- Re-ordered arguments to callback of dav_lock_discover, and made the
   lock object passed back const.
- Fix leaks and crashes due to vague interface definitions.
* API change to dav_propfind_set_complex: use a callback to return the
  'private' structure.
* NEON_NORMAL_BUILD and NEON_LIBTOOL_BUILD macros defined for setting
  up neon's Makefile in a bundled build: see macros/neon.m4.
* NEON_VPATH_BUNDLED macro added which takes separate srcdir and
  builddir arguments for supporting VPATH builds (thanks to Peter Moulder
* Added optional final argument to NEON_(VPATH_)BUNDLED, which gives
  a set of actions to be run if the bundled build is chosen.
* NEON_SSL checks for OpenSSL in /usr too.
* API change: when using http_session_decide_proxy, it MUST be called
  before using http_session_server to prevent the DNS lookup on the origin
  server being optimised out.  The real scheme in use is passed to the
  callback now.
* New function, dav_207_ignore_unknown, to ignore any unknown XML fragments
  in the 207 response.  Used by properties layer.

Changes in release 0.9.2:
* Fix using both dav_propfind_set_complex and dav_propfind_set_flat with the
  same propfind_handler.

- Make it the *callers* responsibility to free() the private structure.
* Fix a few arguments/variables which mirrored globally declared symbols.

Changes in release 0.9.0:
* Removed old dav_propfind_* interface, replaced with a better, more
  powerful, and easier to use interface:

- 'dav_propfind_*' interface for fetching flat and/or "complex" (structured
   XML) properties.
- Lets you retrieve the 'status' information, to see what happened if
   fetching the property failed (e.g 404 Not Found).
* Fixes to doc/using-neon.txt (thanks to Greg Stein).
* Allow building when srcdir != builddir (Mo DeJong <mdejong@cygnus.com>)

  be used by users of dav_207_* code (incl. use of dav_propfind_*
* New NEON_* autoconf macro interface:
- Use NEON_BUNDLED if sources are bundled, otherwise NEON_LIBRARY.
- The NEON_XML_PARSER macro is NOT called automatically.  You must
   call this yourself if using NEON_BUNDLED; see doc/using-neon.txt
   for details.
* Fix use of 'socket' in nsocket.h function prototypes (Greg Stein).
* Remove extra backslash at line 69 of src/Makefile.incl (Dirk Bergstrom).
* Examples directory is now a separate package.

Changes in release 0.7.5:
* Fixed workaround for linking against a libtool-built expat (Greg Stein).

Changes in release 0.7.4:
* Fix for fd leak on connect failure (David Sloat <d.sloat@f5.com>).
* Fix for Digest auth against IIS5 (David Sloat).
* Workaround for linking against a libtool-built libexpat.la (Greg Stein).

Changes in release 0.7.3:

Changes in release 0.7.2:
* Define SHELL in Makefile (thanks to Eric Mumpower <nocturne@arepa.com>).
* Added 'all' target to Makefile (Greg Stein <gstein@lyra.org>)
* Added '--with-expat' argument to configure (Greg Stein)
* Added 'dav_propfind_destroy' function.

Changes in release 0.7.1:
* Don't register response body/header authentication callbacks if no
  credentials-supplying callback has been registered (speed optimisation).

Changes in release 0.7.0:
* Deprecated use of 'NULL' to http_add_response_header_handler.
  New interface, http_add_response_header_catcher, to register
  a callback which is passed ALL response headers regardless of name.
* Speed optimisation (~10%?): storing response-header handlers in a
  hash table for faster look.
* New SBUFFER_CAST() macro for getting to the 'char *' of an sbuffer
  as fast as possible.

Changes in release 0.6.1:
* Fix for retrying request if connection is closed by server.
* Make redirect hook work for >1 request per session.

Changes in release 0.6.0:
* New interface to allow following HTTP redirects (301/302 responses).
  A callback must be given to get user confirmation if the request method
  is not GET, HEAD, or PROPFIND.
* New interface to determine whether the proxy server should be used
  for a given request: http_session_decide_proxy.
* Fix nget build again. Support automatic redirects in 'nget'.
* Add --with-extra-includes and --with-extra-libs configure parameters
  to point configure at

Changes in release 0.5.1:
* Prevent segfault if USE_DAV_LOCKS is defined, and a locking session
  is not registered (thanks to David Sloat).

Changes in release 0.5.0:
* Rename xmalloc, xstrdup etc to ne_malloc, ne_strdup etc.
* Some speed optimisation in response-header reading.
* Use 'off_t' rather than 'size_t' in sock_progress callback,
  sock_readfile_blocked, and sock_transfer.

Changes in release 0.4.2:
* Fix for sending request bodies after getting 100-continue response.

Changes in release 0.4.1:
* Fix nget build.

Changes in release 0.4.0:
* Install library headers into .../include/neon not .../include/libneon
* Install all necessary library headers.
* Compile support for WebDAV locking throughout the library
* Rename md5.h to neon_md5.h (avoids conflict with md5.h in OpenSSL)
* Rename socket.h to nsocket.h (avoids possible conflict with C library)
* Update licensing notice on macros/neon*.m4: note that these files are
  NOT under the LGPL, and can be used in other packages regardless of
  the license the package uses.
* Update NEON_LIBRARY m4 function to allow optional specification of
  names of bundled neon/expat source directories.
* Increase socket read timeout to 60 seconds.
* Added an POST method: from Sander Alberink <sander.alberink@cmg.nl>.
* Added 'http_get_request_headers' to return the sbuffer containing
  all request headers.
* Allow passing NULL as name to http_add_response_header_handler:
  the handler callback is passed the entire header string, of ALL
  response headers.

Changes in release 0.3.1:
* Compile fix for dav_locks.c (thanks to Paul D'Anna)

Changes in release 0.3.0:
* Rewrite of socket handling layer. All sock_* functions changed.
* Added basic SSL support: --with-ssl (requires OpenSSL).
  NOTE: Certificates are NOT presented for verification.
* 'nget' accepts URL's using the 'https' scheme.
* New example program, 'nserver', to display the Server: string,
  e.g. 'nserver https://www.eu.c2.net/'
* Fixed request re-send when persistent connection times out.
* "Hooks" support: allow external hooks into the HTTP request/
  response dispatch loop.
* New printf-style interface for adding request headers.
* Make symbols used in header files C++-safe (Tom Bednarz).
* WebDAV locking support: lock discovery, LOCK (exclusive/shared)
  UNLOCK. "If:" headers are sent as appropriate. Simple interface
  for implementors of new methods to indicate which locks are
  required for the method.
* Primitive HTTP cookies support.
* Primitive hack at a GNOME-based GUI example program "nbrowse".
  Enable build with --enable-gnome-examples. It crashes, and
  not much else. Requires GNOME and POSIX threads. Example usage:
       'nbrowse dav.ics.uci.edu /msdav/'
  Many thanks to Lee Mallabone for Gtk help, and showing how to
  use Gtk and threads.

Changes in release 0.2.0:
* Use libtool: new configure options to select whether to build
  shared and/or static libraries. Should build shared libraries
  portably now.  
* Complete rewrite of the hip_xml interface to use opaque pointers.
  New functions: hip_xml_create, hip_xml_destroy: create parser.
  hip_xml_{set,get}_error: Access to error string.
  hip_xml_add_handler: Register callbacks for a set of elements.
  hip_xml_valid: Returns whether the parse was valid or not.
  Removed functions: hip_xml_init, hip_xml_finish.
* Removed functions made reduntant by above changes in dav_207.
* Don't include config.h in header files
* Fix PROPFIND allprop request body (Michael Sobolev)
* Added C++ safety macros around header files.
* Added neon-config script for getting correct CFLAGS and LIBS
  values for using libneon in applications.

Changes in release 0.1.1
* Fix for short writes in GET

Changes in release 0.1.0
* Initial release.
