+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.
