-Possible compatibility problems with earlier versions marked with '*'.
+Added ICU chain component - which used to be part of Pazpar2.
---- IN PROGRESS
+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 bý
+the we proxy address, followed by command, then follwed by he regular
+"virtual" addresss. For example,
+connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
+
+--- 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
+series).
+
+Added partial support for ISO5428-1984, which is the "Greek alphabet coded
+character set for bibliographic information interchange". By Giannis Kosmas.
+
+Added documentation on new OID API.
+
+--- 3.0.0 2007/05/02
+
+Changes to generic frontend server interface: added new member
+'query_charset' for bend_initrequest structure. A backend init handler
+should set this member to its native character set for query terms.
+When defined, the frontend server logic will announce this character set
+to a client if the negotiationModel bit is set by the client. All server
+implementors are encouraged to specify this. If a backend server does not
+specify this a warning is issued using yaz_log(YLOG_WARN,..).
+
+Added CCL utility to remove terms (stop words) from resulting RPN
+tree. This is handled by functions with prefix ccl_stop_words_ .
+
+New ZOOM C option, "rpnCharset", which allows client-side conversion of
+terms in RPN queries.
+
+Clean-up the CCL API. Moved some internal structures from ccl.h to
+private header cclp.h. Changed ccl_parser_create so that a Bibset must
+be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
+This is replaced by ccl_parser_find_str which takes a string instead.
+
+Split YAZ library into two libs : libyaz.la and libyaz_server.la.
+libyaz.la is the core of YAZ except the generic frontend server and
+does not depend on POSIX threads anymore. libyaz_server.la is the
+generic frontend server facilities and uses POSIX thread functionality
+if available. The libyaz.la no longer depends on POSIX threads because
+the number of global structures is limited. NMEM no longer re-uses blocks
+between threads ; it simply free's memory immediately but allocates in
+"large" chunks as usual. We don't expect any performance penalties
+because of this. The yaz_log system is still using a global log_level so
+caution must be taken when modifying it with yaz_log_init_.. +
+yaz_log_mask_str. This, however, should not cause any trouble because
+these functions are called during initialization of application code
+anyway. `yaz-config --libs server` returns libs for server applications;
+`yaz-config --libs` returns libs for non-server applications.
+
+New OID database - with public definitions in oid_db.h. Removed old OID
+database including the head oid.h and definitions such as enum oid_value
+and struct oident. The new OID database uses the same string names as
+before but the 'protocol' is gone. There are now only two representations
+raw OID (int *) and string. Functions with prefix yaz_string_to_oid
+converts from string to OID; functions with prefix yaz_oid_to_string
+converts the other way.
+
+Change to emit_term() in CQL-to-PQF query translation: when a term has
+the /regexp relation modifier, do not process it for leading and
+trailing "^" and "*", which have quite different meanings in regular
+expressions.
+
+Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
+write handlers no longer carries a 'last' parameter. This will make
+yaz_iconv flush "less" characters. A flush is performed by call to
+yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
+
+Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
+removed, because function yaz_query_to_wrbuf does the same.
+
+API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
+wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
+
+Deprecated MARC utility functions removed.
+
+Changed prototype of yaz_marc_decode_buf: const char for result and size_t
+for rsize.
+
+Branch split: YAZ_2_1_55_branch
+
+--- 2.1.54 2007/03/16
+
+Fix to ZOOM-C so that transparent reconnection is properly handled on
+connections that are in asynchronous mode.
+
+Fixed compilation on OpenBSD 4.0.
+
+Large strings in GRS-1 records are now properly displayed in yaz-client.
+
+Added character conversion support for "advancegreek"; based on patch from
+Giannis Kosmas.
+
+Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
+sequence is met. Before the error was not set so it would be unknown.
+
+Adjust yaz-marcdump MARC reader so that it skips until record separator
+is read
+
+--- 2.1.52 2007/03/07
+
+ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
+Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
+fd_set structure used as a bitmask for the FDs to be selected on.
+
+Using ACX_PTHREAD macro to check for POSIX threads.
+
+Fixed have-vsnprintf check.
+
+--- 2.1.50 2007/02/23
+
+Fixes for configure on BSD. Bug #900.
+
+Added snprintf/vsnprintf wrappers for systems that don't have
+limits (heavens forbid).
+
+Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
+created before all previous tasks were completed and removed from the
+task queue, the new task could be removed by a mistake.
+
+Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
+
+Implemented pass-through CQL-to-PQF conversions. Bug #861.
+
+Fixed bug #832: Problem with MARC/charset in yaz-client.
+
+Fixed bug #668: save command line history for yaz-client.
+
+Fixed bug #830: pkg-config support.
+
+--- 2.1.48 2007/01/23
+
+Extended ZOOM result set options with two options that may be read by
+a client: resultSetStatus and presentStatus with values as specified for
+the ASN.1. See:
+http://www.loc.gov/z3950/agency/markup/04.html#Search-status
+
+Fixed bug #827: Using SSL fails on Debian etch.
+
+Fixed bug #826: Weird looking chars for set of MARC records.
+
+Implemented alternative Item Order package for ZOOM. If option "doc" is set,
+that is treated as an ItemOrder with itemRequest being an XML document
+external. The value of "doc" is the content.
+
+Extended the GFS search facility. New member of bend_search_rr
+'estimated_hit_count' signals that hits is known to be an estmate
+(higher or lower than real hit count). New member 'partial_resultset'
+signals that the search was partial (hit count is lower or equal than
+real hit count). For Z39.50, the information is stored in resultSetStatus
+member of SearchResponse APDU. For SRU, the information is signalled
+via SRU diagnostic 59: "Result set created with valid partial results
+available".
+
+Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
+
+--- 2.1.46 2007/01/13
+
+Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
+
+Added ZOOM_connection_peek_event.
+
+Implemented Generic select hook for ZOOM (bug #803). This is achieved with
+the following new functions:
+ ZOOM_event_nonblock, ZOOM_connection_process,
+ ZOOM_connection_get_{socket,mask,timeout},
+ ZOOM_connection_fire_event_{timeout,socket}.
+The existing blocking event handler, ZOOM_event, is a wrapper for the
++ blocking ZOOM_event_sys_{poll,select}.
+
+Implemented function ccl_xml_config which parses XML version of CCL
+configuration (bug #798).
+
+Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
+
+Added timings utility (yaz/timing.h)
+
+--- 2.1.44 2007/01/03
+
+Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
+Libxml2 tree.
+
+Fixed bug #779: Rotation of apdu.log fails.
+
+Fixed for character set conversions:
+ Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
+ Honor G1 set in MARC-8 decoding.
+
+--- 2.1.42 2006/12/17
+
+Fixed bug #775: char conversion does not handle Alternative UTF-8
+sequences.
+
+Implemented function yaz_marc_read_line which parses MARC line format
+records. There is a wealth of formats out there. So far, this function
+reads line records produced by yaz_marc_write_line.
+
+yaz-marcdump's options -x, -X, -I, -e have been replaced with the
+more generic and easier to remember(!) options: -i format and -o format
+which specifies input format and output format respectively - where
+format is one of "marc", "marcxml", "line", "marcxchange".
+
+Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
+does not print anything except warnings for records.
+
+For yaz-marcdump, added support for MARC split into files (-s) with a given
+chunk size (-C).
+
+Changed the SRU update structures and codecs to reflect the SRU pre 1.0
+spec, at http://www.loc.gov/standards/sru/record-update/
+This has changed the binary layout of the following structs:
+Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
+bend_update_rr . Patch by Ko van der Sloot.
+
+Added GFS utility function bend_assoc_is_alive which returns 1 if
+association is still alive (client is connected); 0 otherwise (client
+closed connection). This allows busy servers to stop working for
+impatient clients.
+
+Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
+been a separate piece of software. This version of ziffy has been modified
+to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
+
+Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
+
+Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
+Client code may now interrogate options such as "init_opt_sort" to
+find out whether the server claims to support various options.
+
+--- 2.1.40 2006/11/27
+
+Added utilities yaz_{set,get}_esn to set/get element set name from
+record composition.
+
+Removed the build of libyazthread.la. The libyaz.so is the threaded version
+of YAZ and has been so since YAZ 2.1.10.
+
+Implemented ZOOM_record_error which returns error information for
+record (surrogate diagnostic).
+
+--- 2.1.38 2006/10/31
+
+Updates for SRU Update by Ko van der Sloot:
+1. Changed name from "operation" to "action"
+2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
+versions in the code, marked as 'backward compatible'.
+3. Added diagnostics for SRU Update.
+
+Fixed bug #709: Records are fetched in wrong format when tasks are queued.
+
+Fixed bug #707: CQL->RPN ignores lines with leading spaces.
+
+Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
+
+For GFS, fixed problem with SRU diagnostic 'First record position out of
+range' being issued for 0 hits.
+
+zoomtst10 part of Windows Build.
+
+--- 2.1.36 2006/10/13
+
+Implemented yaz_filepath_comp which splits a path into file path
+components (required by Zebra 2.0.3+).
+
+Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
+BSD inspired license until now so this should not have any real impact on
+anybody. See http://www.opensource.org/licenses/bsd-license.php
+
+Fixed bug #687: Missing log lines.
+
+Fixed bug #678: CQL to PQF translation does not preserve double-quote
+escaping.
+
+Fixed bug #689: SRU diagnostics to be added.
+
+Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
+whether a connection is idle (no more work do do).
+
+--- 2.1.34 2006/10/04
+
+Change type of optval from long to int for invocation of setsockopt with
+the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
+
+Added support for specifying the max log file size for the Generic
+Frontend Server. The size is given with option -r.
+
+--- 2.1.32 2006/09/21
+
+Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
+
+--- 2.1.30 2006/09/17
+
+Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
+in YAZ 2.1.28.
+
+Fixed bug in Generic Frontend Server that could cause a server to stop
+accepting new connections. Bug only seen on dual CPU Windows 2003 server.
+
+For the generic frontend server, the maximum record size is used as maximum
+size of incoming packages (SRU + Z39.50). The value until was previously
+only used in Z39.50 Init negotiation and, later, in a session controlled
+sizes of records returned. This is controlled using -k option. It can be
+specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
+
+--- 2.1.28 2006/09/04
+
+TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
+friendly now.
+
+Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
+
+New option for yaz-marcdump -lpos=value which allows setting a portion
+of MARC header to a certain value.
+
+Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
+
+ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
+SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
+
+--- 2.1.26 2006/08/15
+
+Fixed problem with SRU mode type (soap, get, post) for yaz-client
+and ZOOM-C.
+
+Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
+
+--- 2.1.24 2006/08/08
+
+Fixed MARC ISO2709 encoding routines to deal with character set
+conversion.
+
+Minor changes to GFS logging. Database included in search request log
+line.
+
+Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
+cached/multiple records.
+
+Shared libraries are built by default on Unix+configure.
+
+Changed cql2pqf transformation to use a different evaluation order. The
+new order is: always, relation, structure, position, truncation, index
+and relationModifier. Old order was: always, relation, relationModifier,
+structure, index, position, truncation. Note that the the latter ones
+override former ones for identical attributes.. The new scheme means that
+it is possible to override any existing attribute with a relationModifier.
+And also that it is possible to override everything for the index rule
+(except the ones listed in relationModifier). No order is perfect but this
+one, we believe, covers more real cases.. The "always" should have been
+called "default", since the attributes there can be overridden with all
+the rest.
+
+For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
+compilation phase, but also for yaz-config --cflags output. This allows
+us to have public headers with Libxml2 stuff in them . It should also,
+eventually, make Libxml2 checks redundant in packages using YAZ, such
+as yazproxy.
+
+--- 2.1.22 2006/06/15
+
+Changed SRU update structure bend_update_rr so that SRU diagnostics are
+stored in uri, message and details.. Previously diagnostics were stored
+in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
+compatibility.. but he's probably the only one affected, so.
+
+Added support for CCL, compiled on the client side, in ZOOM-C. This
+is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
+input; the resulting query objects can be used for for searching with
+ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
+
+YAZ' configure searches for OpenSSL by default.
+
+SSL comstack uses SL_CTX_use_certificate_chain_file rather than
+SL_CTX_use_certificate_file. See
+http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
+for more info. Thanks to Ko van der Sloot.
+
+--- 2.1.20 2006/06/02
+
+Bug #600: SRU GET, POST support for yaz-client. Introduced
+command 'sru' which selects method SOAP/GET/POST.
+
+Allow missingValueAction to be specified for the sortspec string -
+function yaz_sort_spec. By default, the missing value action is null.
+Use ! to specify "abort". Use = followed by stringvalue to specify default
+value.
+
+Ensured that Present-handler (if defined) is called in GFS before any call to
+fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
+searchRetrieve requests.
+
+Documentation for YAZ is now based on the Docbook XML/XSLT using
+xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
+is no longer depending on jade/openjade or docbook-to-man scripts.
+PDF is no longer part of the distribution - but can optionally be
+made using DSSSL/jadetex or FOP.
+
+Added retrieval handling support in Generic Frontend Server to support
+conversion between MARC/XML as well as XSLTtransforms. See
+etc/yazgfs.xml for an example.
+
+Added Authentication support to Generic Frontend Server in SRU
+mode. Authentication using HTTP Basic is supported, as is the use
+of 'x-username' and 'x-password' parameters in the request itself.
+
+Added support for a new character set MARC8s identical to MARC8 except
+that it converts combined characters to single Unicode characters in the
+Latin-1 range (when possible).
+
+--- 2.1.18 2006/04/24
+
+ASN.1 compiler 0.4: generates brief Doxygen file header for
+generated .h/.c files.
+
+Utility yaz_iconv now supports conversion to MARC-8.
+
+New facilities for the MARC module. The reading - and writing of
+content are separate methods for the yaz_marc_t handle. The following
+read functions are available: yaz_marc_read_iso2709 (Reads MARC in
+ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
+format). Write functions have prefix yaz_marc_write_.. The existing
+utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
+available. Removed support for OAI-MARC and simplexml (not the
+simplexml from PHP5).
+
+Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
+to be returned for this connection.
+
+--- 2.1.16 2006/03/31
+
+Allow multiple languages and charsets to be specified with
+yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
+ negcharset iso-8859-1,utf-8
+
+Translation of proximity nodes from CQL into PQF now works.
+
+Moved to automake 1.8, 1.9.
+
+Added function yaz_log_set_handler which allows a log handler to be
+installed. This handler will be called for all log messages. Output
+to file is also produced; but that can be disabled by passing NULL
+fname to yaz_log_init_file.
+
+Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
+
+For SRW (including GFS), accept application/soap+xml as content-type
+for SOAP msg.
+
+For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
+produces NO stylesheet reference even if a default stylesheet is specified
+in GFS XML config.
+
+--- 2.1.14 2006/03/14
+
+Updated Windows package to include yazd.dll + yazd.lib for the
+Development component.
+
+If the environment variable YAZ_LOG is set, then it is used as a
+string indicating the default level of logging to use if not
+overridden by calls to yaz_log_init() or yaz_log_init_level(). If
+it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
+used as before. So, for example, to omit warnings from YAZ logging,
+ export YAZ_LOG=-warn
+
+cql_transform() now map structure and other attributes before indexes,
+so that index-specific structures and other attributes can override
+defaults. So now a combination of mapping specifications such as:
+ structure.* = 4=1
+ index.dc.date = 1=date-modified 4=5
+does the right thing.
+
+cql_transform() now also respects the "always" mapping specification,
+which establishes an initial set of attributes to be used for all
+terms except where overridden by more specific attributes associated
+with the index, relation or modifier.
+
+Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
+which mode to use; one of "post", "get" or "soap" (SRW, default).
+
+Fixes for yaz_iconv routines: changed trie-based character set conversions
+to use only non-negative values for bit fields due to Sun's C compiler not
+supporting negative values.
+
+Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
+sequences where not read correctly. Fix by Rustam Usmanov.
+
+Updated win/makefile to use options, settings which makes things
+compile with VS C 2005.
+
+--- 2.1.12 2006/02/01
+
+Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
+
+In ZOOM socket code, use select instead of poll on MacOSX.
+
+ZOOM-C now support client-side compilation of CQL into RPN that is
+sent to the server, enabling CQL to be used against all Z39.50
+servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
+ZOOM_query object, and submit it using ZOOM_connection_search().
+The CQL-to-RPN translation uses a configuration file, the name of
+which must be specified in the Connection's "cqlfile" option.
+
+ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
+function, which takes as its start-term parameter a ZOOM_query object
+(which may have had either CQL or RPN set into it).
+
+
+--- 2.1.10 2005/11/29
+
+Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
+GFS to support this as well. Backend handler, bend_srw_update, does the
+update work. Code contributed by Ko van der Sloot.
+
+Allow retrieval of Search Result-1 information in ZOOM by the use of
+options that are attached to a result set. ZOOM documentation updated
+accordingly.
+
+Fixed bug #416: First/second comb characters not handled in the MARC-8 to
+UTF-8 conversion. Patch by Raj Patel.
+
+Added option -m to GFS to control formatting of timestamps in log file.
+
+Added 'exit' as synonym for 'quit' in yaz-client
+
+Added support for specifying SRW resultSetId + resultSetIdleTime in a
+Generic Frontend Server's search handler. Refer to include/yaz/backend.h
+for the new members. Patch by Ko van der Sloot.
+
+Added support for SRU POST. It is supported for content-type
+application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
+
+Do not build the separate Multi-threaded (MT) library libyazthread.la.
+Instead make the library libyaz.la multi-threaded. Threading as a whole
+can still be disabled by configure option --disable-threads. Previosly,
+with older GLIBCs there were problems with MT libs under Apache. This
+has now been fixed a long time ago.
+
+Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
+applications.
+
+CQL module modified to be case insensitive for relations/indexes/operations.
+
+Fixed bug in CQL transform code: incorrect value relationModifieder
+was used.
+
+Added 'show all' command for yaz-client which retrieves all results
+for last search.
+
+Added new yaz-client, xmles, which takes a (private) OID and
+a document to be sent as an extended service request.
+
+Describe new yaz-client commands wait_response and set_auto_wait.
+
+Increase TCP/IP listener backlog from 3 (which I am guessing was
+copied from the SunOS manual entry way back when) so SOMAXCONN, so
+that the socket will queue as many incoming connections as it's able
+to handle ongoing connections. In other words, it will never now
+refuse a connection that it would be able to handle merely because
+it's not got around to accepting() enough of the pending connections
+yet. This is the behaviour anyway under Linux, where the listen()
+argument is ignored; but not under BSD and on systems such as
+MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
+YAZ-based servers should now be uniform across operating systems in
+this respect.
+
+yaz-marcdump uses 64-bit file access on some systems. This is enabled
+on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
+This allows yaz-marcdump to read large MARC batches (>2 GB).
+
+Modified all YAZ source files - except the source which is auto-generated
+by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
+all source files.
+
+Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
+corresponding to the existing *_setl() function. These allow option
+values containing arbitrary valuues.
+
+Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
+ZOOM_resultset_sort() in new applications. Its behaviour is identical
+except that it returns an indicator of whether or not the sort
+criterion was accepted (0 for OK, -1 for invalid).
+
+--- 2.1.8 2005/06/07
+
+Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
+MARC output rather than returning "new" buffer.
+
+yaz-client warns about unknown init options.
+
+Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
+
+--- 2.1.6 2005/05/24
+
+Added support for SRW sort in Generic Frontend Server. Patch
+by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
+sortKeys - or NULL if none is provided.
+
+Fixed bug #307: It was impossible to specify indefinite/no timeout
+for ZOOM_event. Special timeout value -1 now means indefinite timeout
+(i.e. no timeout).
+
+Added support for multiple languages and charsets to be specified in
+ZOOM. Each charset/language is separated by a blank. If negotiation is
+in effect in init-response, Option
+"negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
+Code based on patch by Vasiliy Osadchuk.
+
+Fixed bug #306: infinite recursion that occurred when calling
+yaz_log_level_init as the first call (before other log level or
+nmem_init calls)
+
+Fixed bug in scan handling in front end server: if preferred-Position-In-
+Response was non-present, a NULL pointer referece was performed.
+
+--- 2.1.4 2005/04/26
+
+Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
+diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
+now defined for all those error codes. So instead of putting 109 in
+your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
+are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
+
+Modified the yaz-marcdump utility to skip garbage bytes between MARC
+records in a file.
+
+Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
+
+Program yaz-client now exits and produces an error message if multiple
+Z39.50 servers are specified on the command line (none or one allowed
+only).
+
+Program yaz-marcdump skips garbage bytes between ISO2709 records rather
+than abort.
+
+--- 2.1.2 2005/03/16
+
+Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
+
+Fixed bug #272: Preserve spacing for CCL terms.
+
+--- 2.1.0 2005/03/14
+
+Added support for virtual hosts and multiple backend servers for
+the YAZ frontend server. The configution is XML based and
+support specificition of CQL to RPN mappings and explain information.
+See section "Virtual Hosts" in the YAZ manual.
+
+Extended OPAC display utility. OPAC display utility renders
+bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
+to supplement yaz_marc_decode_wrbuf.
+
+Fixed a bug in MARC decoder that could caused it to crash for some
+invalid MARC records. More diagnostics and warnings where added in
+XML output (warnings, etc are stored in comments).
+
+--- 2.0.34 2005/02/08
+
+Fixes for UNIX domain sockets. Bug #261.
+
+Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
+
+Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
+Added yaz_marc_subfield_str which defines subfield lead string which is
+used in YAZ_MARC_LINE format. Default string is blank+$. Added
+yaz_marc_endline_str which defines end of fields string used in
+YAZ_MARC_LINE format. Default string is newline.
+
+Experimental support for MarcXChange. This format can be produced
+by yaz-marcdump and is implemented in yaz_marc_decode - functions.
+ http://www.bs.dk/standards/MarcXchange.xsd
+
+Added yaz-client commands scansize that sets maximum number of
+entries to be returned by scan.
+
+--- 2.0.32 2005/01/11
+
+Added support for SRW scan in yaz-client and Generic Frontend Server.
+
+* Added whereInList member to SRW Scan Term.
+
+* Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
Fixed NMEM system to return aligned blocks on the smallest boundaries
that are suitably aligned for all possible types on the particular
