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 + 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. + +--- 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_process_event, + 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
