+--- 5.2.0 2014/06/12
+
+Allow ZOOM caching using redis. New ZOOM option "redis" controls it.
+
+RPM: do not build with libmemcached support. The libmemcached library
+on CentOS 5/6 does not work reliably for us (redis to the rescue).
+
+configure: only allow libmemcached version 0.40 or later. That's the version
+on Debian squeeze. We recommend libmemcached version 1.0 or later. If
+that's not an option, consider redis.
+
+--- 5.1.3 2014/06/04
+
+Fix dup ZOOM_EVENT_RECV_RECORD events for SRU/Solr YAZ-768
+
+Fix zoom+memcached: present request out of range YAZ-767
+
+--- 5.1.2 2014/05/30
+
+CCL: add new qualifier r=omiteq which will omit relation=equals
+for ordered relations. This should be used in combination with either
+r=r or r=o. YAZ-766
+
+GFS: prevent truncation/overflow in retrieval phase. YAZ-763
+
+Solr: simplify yaz_solr_decode_response
+
+Solr: use different local var for string manipulation
+
+Solr: Get rid of hardcoded limit of extra_args
+
+Solr: encode lucene query type YAZ-736
+Make sure the queries are treated as traditional "lucene", because that's
+what YAZ generates.
+
+Fix ZOOM HTTP redirect failing on Windows+Solaris YAZ-755
+
+--- 5.1.1 2014/04/22
+
+Build packages for Ubuntu Trusty Tahr 14.04 LTS
+
+wrbuf_cstr: fix off by one error.
+
+wrbuf_buf: make it always return non-NULL
+Also, wrbuf_buf will return same buffer as previous call to wrbuf_cstr.
+
+--- 5.1.0 2014/04/17
+
+Doc: move main YAZ manual to book.xml; use nxml YAZ-758
+
+zoomsh: offer option -a apdulog
+As we're used to from yaz-client and GFS based servers.
+
+ZOOM: new setting apdufile. Sets name of APDU file. If not given,
+existing setting apdulog takes effect.
+
+Add odr_setprint_noclose. It's like odr_setprint, but does not fclose at
+odr_destroy.
+
+Add wrbuf_cstr_null.
+
+Add re-entrant CQL/Solr/RPN query conversion functions.
+The re-entrant functions are: cql_transform_r,
+cql_transform_rpn2cql_stream_r, solr_transform_rpn2solr_stream_r.
+These have same functionality as cql_transform,
+cql_transform_rpn2cql_stream, solr_transform_rpn2solr_stream. They
+return the additional infomration as WRBUF to make them re-entrant.
+
+Remove CQL to Solr conversion and base solr_transform_t on
+cql_transform_t. The RPN to Solr is indeed in use. It uses exact same
+data structure as cql_transform_t.
+
+cql2pqf utility allows RPN to Solr conversion
+
+Fix assert in ZOOM when http connect fails YAZ-757
+
+--- 5.0.22 2014/04/09
+
+ZOOM: Call cs_rcvconnect during HTTP redirect YAZ-754

+Offer new utility function zget_AttributeList_use_string.
+
+New conversion step, solrmarc, for record conversion module.
+
+--- 5.0.20 2014/03/13
+
+Fix gcrypt initialization for threaded mode. On systems were GnuTLS
+did not initialize gcrypt for threaded mode, wrbuf_sha1_write could
+throw an assert.
+
+--- 5.0.19 2014/03/10
+
+Fix ZOOM_connection_Z3950_search: Assertion YAZ-750
+The standalone ZOOM sort was completely broken since 5.0.13.
+
+ZOOM: generate event Connect rather than None for partial connect
+(in fact getaddrinfo resolving).
+
+ZOOM: only supply clientIP for InitRequest. Rather than for all
+APDU types.
+
+GFS: peer_name adds X-Forwarded/Client-IP to value YAZ-749
+
+COMSTACK flag CS_FLAGS_DNS_NO_BLOCK. This will enable non-blocking
+getaddrinfo . This flag is passed to cs_create macro and cs_create_host,
+cs_create_host_proxy functions. ZOOM C uses this flag. YAZ-744
+
+New "Facets" section in the documentation.

+
+Fix ZOOM_connection_connect SEGVs if host==NULL YAZ-746. Problem
+introduced in 5.0.12.
+
+Fix: Setting env YAZ_LOG makes YAZ hang YAZ-745
+yaz_init_gloabsl calls yaz_log_init_globals calls yaz_log_mask_str_x .
+Do not call yaz_init_globals from log_mask_str_x. Problem introduce

+
+Describe memcached option for ZOOM.
+
+ZOOM: throw present request out of range again YAZ-739
+Was removed in YAZ 5.0.13.
+
+--- 5.0.13 2014/02/18
+
+yaz_log MUTEX protected and pthread_atfork is used to avoid dead-lock
+with localtime_r when threads + fork is used (such as Metaproxy).
+
+yaz-config: quote some RHS values (that might include blanks)
+
+zoomsh: shows SearchResult-1
+
+zoomsh: sortby command
+
+zoomsh: use proper list of connections and result sets YAZ-725
+
+Avoid yaz_log in sigterm handler for GFS YAZ-737
+Logging is still performed, but outside sig handler.
+
+New ZOOM C feature: result-set caching with memcached. Example:
+ zoomsh "set memcached --server=memcachehost" "connect zurl" "search query"
+
+Remove SSL via OpenSSL support YAZ-732
+Also deprecate two functions from comstack that aren't working with
+GnuTLS: cs_get_ssl, cs_set_ssl_ctx.
+
+Revert "Bison: use %name-prefix directive rather than -p option"
+
+--- 5.0.12 2014/01/22
+
+Prefix URL with http:// if sru setting hints SRU/Solr mode YAZ-731
+
+SRU GET/Solr base URLs may hold additional ?args YAZ-729
+ZOOM option extraArgs already does this, though. It seems useful
+when dealing with Solr targets to limit by filter, eg.
+ http://lui.indexdata.com:8080/solr4/select?fq=database:3902
+
+Remove #fragment for HTTP request encoding YAZ-730
+
+Doc: Update list of DLLs/LIBs
+
+Doc: update href link to Unix utils and Git.
+
+--- 5.0.11 2014/01/15
+
+ZOOM: fix "lost connection" problem with servers that uses both squid
+and another proxy behind it that returns Location headers with relative
+URIs. YAZ-724
+
+zoomsh: do not use readline for stdin (no tty) YAZ-724
+Just use fgets in that case. If the user hits Ctrl-D a new-line
+is also printed.
+
+zoomsh: empty command ignored YAZ-723
+rather than performing exit of zoomsh.
+
+yaz-url utility offers option -v to enable verbose mode.
+
+yaz_url uses yaz_check_location and offers verbose mode.
+
+Add new function yaz_check_location.
+This function gets an absolute URI from Location (HTTP redirect).
+
+cookie API: introduce yaz_cookies_reset
+
+Update cql.y for newer bison YAZ-720
+The important part is that YYLEX_PARAM and YYPARSE_PARAM are no
+longer supported. Instead one must use %lex-param and %parse-param .
+
+--- 5.0.10 2014/01/09
+
+ZOOM/yaz-client: Cookie handling; deal with relative URI in Location
+header. YAZ-719
+
+rpn2solr: support truncation left(2), left&right(3) YAZ-718
+
+Mention SRU version 2.0 in yaz-client man page.
+
+--- 5.0.9 2013/12/20
+
+ZOOM/yaz-client: allow SRU searchRetrieveResponse with incorrect
+namespace.
+
+--- 5.0.8 2013/12/20
+
+Make cs_parse_host public.A
+
+Fix double HTTP dump (-a log would show HTTP packages twice). Bug
+introduced in YAZ 5.0.6.
+
+--- 5.0.7 2013/12/17
+
+Fix buffer corruption for yaz-ztest record fetch.
+
+--- 5.0.6 2013/12/17
+
+Allow yaz-ztest to return user-defined records (one record per file).
+This is enabled by defining environment variable YAZ_ZTEST_XML_FETCH.
+
+Prevent early truncatin of HTTP log. (ODR_PRINT for HTTP streams).
+Use the stream write instead of odr_printf which has a 4K tmp buffer.
+
+Fix encoding of 0x00a4 (unicode to danmarc) YAZ-713
+
+--- 5.0.5 2013/12/09
+
+Add support for MARC-in-JSON. yaz-marcdump and the record conversion module
+can read and write this format. For record format JSON, yaz-ztest returns
+MARC-in-JSON records.
+
+iconv: fixes and more tests for danmarc character set encoding. 0xa733 is
+converted to @å , 0xa732 is converted to @Å instead of @a733, @a732 .
+
+--- 5.0.4 2013/11/22
+
+Improve error reporting for ICU chains YAZ-707
+Report config element+rule when ICU status is "failure".
+
+ZOOM: stop fetching if present response has no records YAZ-710
+Some targets return less records than their hit count would suggest.
+This prevents ZOOM from continuing to fetch records if any present
+response has 0 records in the response.
+
+Ensure that GFS calls exit if any listener fails YAZ-710
+Before, if XML config was in use, it would start the default
+listener @:9999!
+
+--- 5.0.3 2013/11/19
+
+yaz-ztest: -V shows version (like yaz-client -V)
+
+New iconv encoding: danmarc YAZ-692
+
+yaz-client: lslb, ssub, mspn are Odr_ints now YAZ-705
+
+daemon: only wait for immediate child rather than all children. YAZ-704
+
+yaz-client: fix setting of SRU record schema. If scheme was unset, it
+could lead to invalid memory reference.
+
+--- 5.0.2 2013/10/16
+
+yaz-ztest returns schema for MARCXML test records. SRU require that
+recordSchema for records.
+
+GFS: make surrogate diagnostic when yaz_record_conv_record fails -
+instead of non-surrogate diagnostic. This is a per-record failure.
+
+GFS: Allow multiple listenrefs YAZ-554. A server in yazgfs configuration
+may refer to multiple listeners now. Attribute listenref is a comma separated
+list of listen IDs.
+
+GFS: Use xmlconfig path as prefix for fnames YAZ-702. When -f
+option is given for GFS, the dirname of filename (for -f) is used
+as prefix for options such as cql2rpn, ccl2rpn, etc.
+
+Content-Type charset fixes YAZ-701 . Do not inspect charset in
+Content-Type header for SOAP when decoding SRU. The payload (XML)
+itself tells what encoding it is. In response, never supply encoding
+in Content-Type. The response payload (XML) tells what it is (with no
+encoding in XML it's UTF-8).
+
+HTTP decoding: allow blanks in URL paths YAZ-700
+
+--- 5.0.1 2013/10/04
+
+Various fixes for how SRU 2.0 is encoded. Fix NS for SRU 2.0 diagnostics
+and facets. Ensure recordData and recordSchema are always present in
+record element, because they are required.
+
+Remove deprecated functions yaz_uri_val .. and yaz_uri_val_int. Never used
+outside YAZ.
+
+Simplify in a lot of places using odr_strdupn.
+
+odr_create_Odr_oct: null terminate the buffer. Some applications rely on it.
+
+--- 5.0.0 2013/10/01
+
+Increase various buffers in GFS's statserv_options_block
+Change many 'unsigned char *' to 'char *' for ODR-related utilties.
+This change makes many type-casts redundant, and, thus simplifies code.
+
+Remove last bits of WAIS support.
+
+Remove member 'size' from Odr_oct.
+
+Slim down the public part of 'struct odr'. Most elements are not part
+of struct Odr_private.
+
+Add support for SRU 2.0. Since SRU 2.0 is incompatible with earlier
+versions of SRU, yaz-client and zoom C are using SRU 1.2 by default.
+In particular facets are supported in both client - and server side.
+Facets are also supported for Z39.50 and is carried in additionalSearchInfo
+of searchRequest/searchResponse with OID 1.2.840.10003.10.1000.81.5 AKA
+"Facet-1" in oid.csv. The info is defined in facet.asn (which covers
+both request/response). This is what a search handler in the GFS
+will see (regardless of whether operating in SRU mode or Z39.50).
+
+Changes to the srw.h (SRU/Solr) definitions include:
+- New element in Z_SRW_searchRetrieveRequest, queryType (char*) and query
+(char*), which replace union query and query_type (int). This is because
+SRU 2.0 supports a queryType parameter. This also means that, to carry
+PQF, in SRU we can now use queryType=pqf and query=PQFstring , rather than
+x-pquery=PQFstring (extention parameter). The extension parameter
+is still supported.
+- New element, packing, that has information about SRU
+2.0 recordPacking (not to be confused with SRU 2.0 recordXMLEscaping).
+
+New element in Z_SRW_searchRetrieveResponse, resultCountPrecision.
+
+New element, packing, in Z_SRW_explainRequest.
+
+New elements in Z_SRW_scanRequest, queryType and scanClause.
+These replace query_type and scanClase untion. This is similar to what
+happend to search.
+
+--- 4.2.69 2013/10/01
+
+GFS: log when closing down - at least SIGTERM YAZ-684
+Also change formatting WRT PID logging a bit.
+
+Improve display of MARC records with multi-byte subfield IDs YAZ-695
+In some rare cases subfield identifiers are multi-byte characters.
+This will try to deterime length of those and split accordingly.
+This affects display in line mode as MARCXML/MarcXchange. The encoding
+of ISO2709 is the same.
+
+Change inp argument to const for yaz_read_UTF8_char.
+
+yaz-marcdump: fix leaks for MARCXML parsing. YAZ-694
+
+MARCXML parsing: avoid skipping 1st field if no leader. YAZ-693
+
+Better check of marc leader info YAZ-691
+Problem is that some systems generate MARCXML/MarcXchange with
+funny headers. These will not work if encoded as ISO2709.
+Some tests produce new output, due to updated warning messages
+
+cql2pqf: allow PQF queries from stdin (because CQL is also allowed)
+
+yaz-client: display MAB records YAZ-689.
+Thanks for Heiko Jansen for this patch.
+
+New utility z_get_HTTP_Response_server which allows both HTTP server name
+and HTTP server URL to be given in response.
+
+Debian: do not depend on obs tcl8.3.
+
+Debian: do not depend on obs libicu36-dev.
+
+--- 4.2.68 2013/09/23
+
+GFS: pass additionalSearchInfo to search memeber search_input if
+given. Otherwise pass otherInfo. Request for facets and other search
+related things will be passed there in future versions of YAZ.
+
+New ZOOM setting, authenticationMode, which allows authentication
+paramters to be encoded in the URL rather than via HTTP Basic auth.
+YAZ-686
+
+rpn2solr: fix nested AND/OR handling. YAZ-685
+
+Add comparison routines for some Z-types, such as NamePlusRecord,
+RPNQuery, Query, RecordComposition and OtherInformation.
+
+--- 4.2.67 2013/09/19
+
+Don't decode MAB as MARC. Just like we don't attempt to decode
+HTML/XML as MARC. Fixes MAB display problem that was introduced in 4.2.64.
+
+CCL: allow quoted terms for date ranges. YAZ-681
+
+Introduce ccl_parser_qual_search. This function makes old function
+ccl_qual_search, from YAZ 2, available again.
+
+Add yaz_facet_list_to_wrbuf. YAZ-683
+
+--- 4.2.66 2013/09/11
+
+ZOOM: fix record handling for Solr. ZOOM_record_get would return 0, if
+schema was given for search. YAZ-675
+
+Add Solr date range searches. YAZ-621
+
+--- 4.2.65 2013/08/22
+
+ZOOM: another fix for record caching (introduced in YAZ 4.2.64).
+
+--- 4.2.64 2013/08/21 (Broken WRT ZOOM C, do not use)
+
+ISO2709/MARC parse most octet aligned records; not just those that
+are known to be ISO2709/MARC. This makes ZOOM and yaz-client
+MARC parse more records instead of just dumping as is. YAZ-670
+
+ZOOM: proper caching for variations of record schema. YAZ-671
+
+Solr: Check for enging / and perhaps commands (select/term) YAZ-651
+
+--- 4.2.63 2013/07/17
+
+Add yaz_strcmp_null
+
+--- 4.2.62 2013/07/11
+
+New utility z_get_HTTP_Response_details - an extended version of
+z_get_HTTP_Response.
+
+New utility yaz_url_get_error which returns error message of last
+failed yaz_url_exec call.
+
+yaz-url and url functions: allow max HTTP redirects to be controlled.
+
+New functions yaz_file_glob2, yaz_xml_include_glob.
+These functions takes a flags parameter, which, for now only controls
+whether to fail inclusion of a non-existing file (without glob
+pattern) - flags YAZ_FILE_GLOB_FAIL_NOTEXIST.
+
+--- 4.2.61 2013/06/20
+
+For MARC XML parsing, allow record without leader. A fake/default leader
+is inserted and a warning is tagged with the record.
+
+ICU: fix leak in in icu_iter_get_org_info.
+
+--- 4.2.60 2013/06/14
+
+ICU: fix bug in icu_iter_get_org_info (un-init variable).
+
+--- 4.2.59 2013/06/11
+
+Implement z_HTTP_header_remove.
+
+--- 4.2.58 2013/06/11
+
+ICU: Disallow 0 ptrs for some ICU string utilities.
+
+ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
+returns original tokens (before normalization).
+
+CCL: avoid z39.58/regex truncation when not needed. Apply only the
+conversion of those masks, when absolutely necessary.
+
+CCL: configurable masking character - @mask. Default masking character
+is # for CCL.
+
+HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
+full response anyway, so a Transfer-Encoding header will obstruct the
+response.
+
+--- 4.2.57 2013/05/15
+
+COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
+picking a socket. Problem is that some systems has IPV6 support, but
+we can't create sockets for them, so we pick AF_UNSPEC first.
+
+HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
+use content_len to determine resulting Content-Length in HTTP response
+and NOT Content-Length supplied in headers by user.
+
+z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
+z_HTTP_header_add, to avoid having two Authorization headers by mistake.
+
+Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
+content-length.
+
+Fix yaz_base64decode to use proper signed. Problem occurred on platforms
+with big endian and unsigned char (by default).
+
+--- 4.2.56 2013/04/26
+
+Fix yaz-client connect (crash in 4.2.55).
+
+--- 4.2.55 2013/04/26
+
+Fix proxy/host problem for ZOOM that could occur if unix sockets
+was in use.
+
+New Debian package libyaz4-dbg.
+
+Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
+differently in tcpip_close.
+
+--- 4.2.54 2013/04/17
+
+Windows installer of YAZ includes YAZ4J as a component.
+
+CQL: allow "extra terms" again, by default. Thus, the CQL parser
+accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
+and earlier. CQL parser may operate in strict mode where queries
+not conforming to the standard BNF are rejected (syntax error).
+Whether the CQL parser operates in strict mode is controlled with
+cql_parser_strict . Strict mode enabled with option -S for utilities
+cql2pqf and cql2xcql .
+
+yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
+
+--- 4.2.53 2013/04/10
+
+New charset, MARC-8c, which is like MARC-8 but allows control characters
+0x01 through 0x1F, except ESC to be passed through verbatim.
+
+Fix a problem with duplicate sub field character in MARC output. Problem
+happened only when output was MARC-8 encoded.
+
+--- 4.2.52 2013/04/03
+
+yaz-ztest: Use hash for fake hit count. Before, random number was used.
+This is problematic for unit tests using yaz-ztest. This patch also makes
+a hash for CQL queries. For RPN, any term with a leading digit will be
+treated as pseudu hit count (to force any particular hit count by a client).
+
+yaz-ztest: return unique MARC dummy records. Beyond record offset
+24, the author surname is patched with offset to make all records
+unique.
+
+COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
+on system wide default (/proc/sys/net/ipv6/bindv6only).
+@4 binds to IPV4 only. @6 binds to IPV6 only.
+
+Update CQL API documentation a bit
+
+CQL: don't accept extra terms for queries. Makes the CQL parser
+stricly conformant to the standard.
+
+--- 4.2.51 2013/02/12
+
+GFS: scan handler gets extra_args from request and may return extra
+response data . That's for SRU only.
+
+Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
+
+--- 4.2.50 2013/01/30
+
+New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
+
+OPACXML: sync spelling of availabilityDate in XML to that of Schema
+opaxxml.xsd. The schema had the correct spelling of this member always.
+The ASN.1 was mis-spelled and still is (API change) - we are
+not changing this. However, the OPAC to XML conversion had yet
+*another* typo.
+
+GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
+element.
+
+New function, z_ext_record_oid_nmem, which is similar to
+z_ext_record_oid but takes NMEM rather than ODR
+
+--- 4.2.49 2013/01/18
+
+ICU: New conversion element 'join' which joins tokens into one
+with a custom character given by rule attribute.
+
+--- 4.2.48 2013/01/10
+
New GFS search member: present_number. This is a hint to the
search handler how many records are going to be fetched immediately
following search. There's no guarantee that it's going to be the case,
rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
will make it possible to use both single-character mask (#) and wildcard (?)
in CCL . Throw diagnostic for left truncation because that is not supported
