+Add support for extra request / response data for SRU codecs and GFS.
+The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
+for extra data response buffer and length. For the GFS, both request
+and response data (XML) is carried in extra_args and extra_response_data
+for the search handler. Patch by Ko van der Sloot.
+
+--- 3.0.49 2009/10/01
+
+Make a number of functions defined in xmlquery.c static. These have
+never been declared in a public header file (yaz/xmlquery.h) and was
+made public by mistake.
+
+Improve speed of character conversions (iconv utilities). This makes
+conversions from MARC-8 faster.
+
+ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
+unless type desired is "raw". This will prevent type "xml" from
+returning ISO2709 .. Which obviously can not be XML parsed.
+
+Fix memory leak in ZOOM that would occur if option apdulog was used
+on a re-used connection.
+
+Frontend server logs HTTP requests.
+
+Frontend server now sends Z39.50 close when it times out (sesssion has
+been idle for too long). Versions 2.0.30 and earlier also sent close.
+But due to a mistake this was disabled in all versions after that, i.e.
+the server would just close the socket immediately.
+
+yaz-client emits a better message when receiving an unrecognised
+userInformationField.
+
+Skip zero-length subfields when decoding ISO2709. This rare case happens
+if a record has two FS characters in a sequence. Without this patch
+there would be a reference beyond char array in using_code_len fragments
+in marcdisp.c.
+
+Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
+
+--- 3.0.48 2009/08/28
+
+The show command offered by the zoomsh command now takes a 3d optional
+parameter type which is what is passed to ZOOM_record. If the type
+argument is omitted, "render" is used.
+
+RPN to CQL conv may use USE string attributes (bug #2978).
+
+MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
+
+--- 3.0.47 2009/07/08
+
+Function yaz_xml2query allows a diagnostic element in the PQF XML
+representation .. diagnostic@code and diagnostic@addinfo is diagnostic
+code and additional info respectively.
+
+The BER BOOLEAN is now the integral type Odr_bool which still happens
+to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
+typedef'd to Odr_int. This is still an integral 'int', but it may be
+changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
+ASN-1 compiler as well as programs has been updated to use the new types.
+
+--- 3.0.46 2009/06/08
+
+zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
+only the bibliographic record was rendered. For type=opac, an OPAC
+record is only returned if it is present.
+
+iconv: small fix for encoding of advancegreek.
+
+yaz-client: avoid double display of SRU/SRW records (bug #2798).
+
+yaz-client: option auto_reconnect=on really reconnects.
+
+yaz-client: fix bug #2770 - avoid length limit for auth parameters.
+
+server: avoid null ptr ref for for yaz_poll errors.
+
+build: fix RPM build for RHEL 5.3.
+
+comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
+
+--- 3.0.45 2009/03/31
+
+Fixed bug #2709: TCP connect returns Invalid argument.
+
+Fixed compilation for mingw.
+
+Honor charset for raw records (ZOOM_record_get).
+
+Fixed use of errno for threaded mode that was seen on Solaris 10.
+
+Fixed argument passing with blanks in value for Windows Service.
+
+Disable YAZ' own log rotate by default (no 1 GB limit).
+The variable l_max_size which specifies the log file limit is set to 0
+(DISABLED): This is due to the fact that YAZ is most often deployed using
+logrotate. Also YAZ can not perform log rotate because of unsufficient
+permissions (setuid).
+
+--- 3.0.44 2009/02/17
+
+List supported encodings in man page for yaz-iconv.
+
+Fixed missing SSL libs for --libs output
+
+Re-established OID record syntax application-xml. Nobody should use it
+but we don't want to change soname because of this symbol being absent.
+
+--- 3.0.42 2009/02/02
+
+YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
+
+Added member named_result_sets for init handler struct for the GFS. This
+allows a server to disable named result sets.
+
+Removed OID record syntax application-xml.
+
+Added support for rule-based transliterator for ICU wrapper of YAZ.
+
+Fixed bug #1902: yaz-icu XML output.
+
+Make YAZ checks Emacs friendly.
+
+BITSTRING value shows value. Bug #2346.
+
+ISO2709 decoding: skip control characters from indicator data.
+
+Omit sort key by default in yaz-icu's output.
+
+Allow combined single char options (again) for YAZ' options function.
+
+Utility yaz-marcdump got option to display YAZ version (-V).
+
+Allow YAZ to use ICU 3.4.
+
+Added new ICU test case which illustrates removal of diacritics.
+
+--- 3.0.41 2008/12/29
+
+Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
+
+--- 3.0.40 2008/12/29
+
+For configure, using option --without-xml2 also disables Libxslt/Libexslt
+support.
+
+Fixed bug #2352: yaz-marcdump crashes for certain record.
+
+Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
+
+Added support for Danmarc2 to UTF-8 conversion.
+
+Added support for ISO5426 to UTF-8 conversion.
+
+zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
+implementation version.
+
+Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
+
+--- 3.0.38 2008/11/10
+
+ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
+ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
+
+ZOOM C now interprets databaseName option for ZOOM connection as path
+(SRU "database").
+
+Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
+
+Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
+
+Dummy Libxml2 types no longer defined in headers of YAZ'.
+
+Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
+received.
+
+--- 3.0.36 2008/09/26
+
+Various ODR chapter fixes.
+
+Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
+
+Added missing source for Windows compilation, mutex.c.
+
+Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
+
+For SRU connections in ZOOM all records up to "count" are now fetched.
+
+Fixed crash in generic frontend server (and yaz-ztest) which occurred
+in Windows due to bad error handling for Libxml2.
+
+Added facility for sending arbitrary records (ASN.1 any) using
+ZOOM C's Extended service update. Patch by Sam Reynolds.
+
+New options for ZOOM C's connection, logapdu which makes ZOOM log
+APDUs.
+
+--- 3.0.34 2008/06/18
+
+YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
+
+--- 3.0.32 2008/06/12
+
+Fixed memory violation that could occur when decoding UTF-8. This bug
+was only present in 3.0.30 of YAZ.
+
+--- 3.0.30 2008/06/06
+
+Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
+GNU TLS is used by default (if found).
+
+yaz-ztest returns OPAC records if a client asks for OPAC.
+
+Improved speed of MARC-8 encoding.
+
+Added support for lossy and loss-less MARC-8 encoding.
+
+Changed yaz_record_conv_record to be reentrant for XSLT conversions.
+
+Added new Windows Service wrapper (sc).
+
+yaz-client's itemorder command may now send a file.
+
+Fixed yaz-marcdump to allow the use of NS prefix for record element.
+
+Added new function yaz_log_xml_errors.
+
+Allow (but warn) unknown XML attributes in MARCXML parsing.
+
+Handle G1 sequneces in MARC-8 decoding. Bug #2115.
+
+The UTF-8 to MARC-8 conversion now uses a different set of characters
+for Greek symbols. Bug #2120.
+
+--- 3.0.26 2008/02/21
+
+Added yaz_daemon (daemon.h).
+
+Fixed bug #2068: pkg-config trouble
+
+Fixed bug #395: ZOOM_record / OPAC record encoding problems.
+
+--- 3.0.24 2008/01/28
+
+Document --with-xml2 option.
+
+Added OPAC XML XSD (etc/opacxml.xsd).
+
+Allow glob mask for name attribute in retrieval element for the
+generic frontend server's retrieval facility.
+
+Changed yaz_poll_poll to return yaz_poll_except for all returned events
+except POLLIN/POLLOUT.
+
+Fixed error handling in cs_listen. Bug #2037.
+
+--- 3.0.22 2008/01/20
+
+Fixed version in yaz/yaz-version.h.
+
+Fixed bug #2027: Crash when closing connection.
+
+Changed configure so that ICU support is only enabled if only ICU
+and Libxml2 is available (because the ICU chain is XML based).
+
+--- 3.0.20 2008/01/15
+
+YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
+is built. Only this DLL depends on the ICU runtime.
+
+yaz-ziffy is no longer part of YAZ. It is distributed separately by
+Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
+
+Changed license of CCL module to 'Revised BSD'. After consultation with
+remaining members of the original EUROPAGATE consortium, we are re-issuing
+the CCL module without a separate license. The software was developed by
+Index Data as part of a research project. The special license was included
+to help feed usage information back to the project consortium to support
+project evaluation. At this time, the project consortium has long-since
+disbanded, and the majority of the original principals have retired. At the
+same time, we have significantly modified the software during the following
+years, to the point where very practically no original code remains. To
+simplify re-use of the software, we have contacted those members of the
+consortium who could be reached, and agreed to re-issue the module as a
+proper part of the YAZ package.
+
+Tcl scripts uses /usr/bin/tclsh as preferred shell.
+
+CQL closer to being version 1.2 compliant. CQL also allows free-form
+terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
+and user-frendly.
+
+Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
+bug could make Extended services handling crash in the ZOOM layer. This
+bug was only present in YAZ 3.0.18.
+
+--- 3.0.18 2007/12/19
+
+ziffy uses YAZ' options rather than getopt; getopt is unavailable on
+some systems.
+
+yaz-marcdump reads and writes collection wrapped records.
+
+Handle OPAC for record conversion module.
+
+Fixes for ICU wrapper.
+
+Allow ICU libs to be controlled with --with-icu .
+
+--- 3.0.16 2007/11/12
+
+Added yaz_poll which is a wrapper for select/poll. When poll is available
+and non-buggy, it is used, by yaz_poll . This allows more than 1024
+sockets to be in use.
+
+Added ICU wrapper library which exposes ICU http://www.icu-project.org/
+functionality through an XML based configuration (ICU chain). This system
+is useful for search facilities such as Pazpar2 and Zebra that needs to
+perform tokenization of indexed material. The ICU code in a separate
+library libyaz3_icu.a.
+
+Added HTTP tunnel facility for COMSTACK, bug #1752.
+This is a facility that allows a Web proxy, such as squid, to tunnel
+Z39.50 traffic. This facility is "transparent" to must applications
+using YAZ. It's enabled by using pseudo transport connect: followed by
+the proxy address, followed by command, then follwed by he regular
+"virtual" addresss. For example,
+connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
+
+More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
+
+--- 3.0.14 2007/09/21
+
+Fixed bad memory reference in ZOOM_record - cuased by member not being
+initialized. This was a problem only in YAZ 3.0.12.
+
+Fixed bug in conversion from MARC to XML: Non-XML characters in control
+fields were not removed.
+
+Changed the way C code is generated from codetables.xml. Made a MARC-8
+conversion trie for each characterSet section rather than codeTable.
+This is ensure the code can deal with G0/G1 sequences. Use of a newer version
+of codetables.xml from Larry Dixson, LOC. Bug #1464.
+
+--- 3.0.12 2007/09/12
+
+ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
+from ZOOM_record_error).
+
+ZOOM C function ZOOM_record_get returns record schema for type="schema".
+
+Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
+
+Added new ZOOM C connection option 'sru_option' which specifies SRU version.
+
+Better SRW-to-Bib-1 diagnostic mapping.
+
+ZOOM C and yaz-client announces SRU version 1.2 by default.
+
+yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
+GET or POST).
+
+Fixed in yaz_sru_decode to allow other version than 1.1.
+
+--- 3.0.10 2007/08/22
+
+Added support for SRU scan for ZOOM.
+
+Added support for the use of the older versions or Extended Service
+Update in ZOOM. To faciliate this, an option "updateVersion" may be
+set to the version , 1=first, 2=second, 3=third. The third version is
+what ZOOM C has used so far. And that, obviously, is the default.
+
+Added support for CCL queries in Z39.50 queries sent to the GFS (and
+therefore in Zebra and in SimpleServer-based applications). The new
+<ccl2rpn> element in a GFS configuration file, if present, names a CCL
+qualifier file used to transform incoming CCL queries into Type-1 RPN,
+which is passed into the back-end search callback function.
+
+Added support for HTTP Basic authentication in clients: the SRU/W
+codec encodes the username/password elements of the PDU structure
+appropriately, and these may be set using the "user" and "password"
+options in ZOOM-C applications (the same options that are used for
+Z39.50 authentication).
+
+--- 3.0.8 2007/06/25
+
+Fixed bug #1208: SSL appears to be broken in ZOOM.
+
+Fixed bug #1206: Libxml2 include path weirdness.
+
+Added oid_name_to_dotstring.
+
+Allow elementSetName to be specified for ZOOM C record update.
+
+Allow waitAction to be specified for ZOOM C based for Extended Services.
+
+Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
+syntax OID. Bug introduced in YAZ 3 series.
+
+Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
+
+--- 3.0.6 2007/06/06
+
+Fixed bug #1157: yaz-client does not read .yazclientrc from current
+directory. yaz-client now reads commands from file given by option -f
+if specified; then tries to read .yazclientrc in current directory.
+Failing that, it reads .yazclientrc from user's home directory.
+
+Added support for correlationInfo Note and ID for Record Update via
+ZOOM C.
+
+Added yaz-client command querycharset which specifies character set for
+query terms for Z39.50 RPN queries and Z39.50 Scan Requests
+(termListAndStartPoint).
+
+Charset ISO5428:1984 is an alias for ISO5428-1984.
+
+Implemented a way to perform scan in a result set using Z39.50. This
+is achieved by attaching the result set name in the characterInfo
+(type InternationalString) of OtherInformation in the Scan Request PDU.
+The result set is identified in the otherinformation by the new OID:
+ USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
+This allows for scan in result set and faceted search . Zebra did some
+of this in the APT term using attribute type 8 and value being result
+set. Using the OtherInformation approach for this is cleaner and easier
+to work with in proxies and the like. This facility can be used in
+yaz-client using new command setscan which takes a result set as first
+argument, start position (APT) as second.
+
+Changed decoding of SRU XML packed records to deal with servers that
+have recordData with XML data with multiple root nodes. Also make
+comparison for recordPacking case insensitive. Again, one server
+returns "XML" where others return "xml".
+
+For SRU responses allow Content-Type application/xml as well as text/xml.
+
+--- 3.0.4 2007/05/21
+
+Fixed bug in character set conversion of BER strings. Bug introduced
+in 3.0.0.
+
+--- 3.0.2 2007/05/08
+
+For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
+
+For OID class, use oid_class consistently.
+
+Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
