+
+http_rewrite: better handling of <script> content in HTML parser. MP-486
+
+http_rewrite: fix threading issue with regex. MP-482
+
+bounce: don't use strdup for fixed length content. Error occurred in echo
+mode only.
+
+session_shared: expire backend class when no instances left. This
+means memory clean up, but not really a leak fix.
+
+virt_db: fix leak for naked ptr.
+
+cql_rpn: use config relative path for cql2rpn file. MP-481
+
+Updates for upcoming YAZ 5.
+
+--- 1.3.61 2013/08/29
+
+New configuration directories ports.d/routes.d for metaproxy
+configuration. This allows 3rd party packages to install config
+for ports and new routes. MP-477
+
+--- 1.3.60 2013/08/21
+
+Fix metaproxy-config --libs to return non-mt over mt libs.
+The -mt versions do not exist as shared objects and cause
+linker errors for applications linking with Metaproxy.
+Problem present in versions 1.3.56 - 1.3.59. MP-475
+
+HTML: clean up char checks. Add ptr to HTML parse spec
+
+HTML parser stops eating tag when <-char is met  MP-473
+
+rewrite: do not even compare content types, if we don't have any
+the regex_match caused a segfault if we had no content-type in the
+headers. MP-471
+
+rewrite: within header=... matches only the header value
+Used to match the whole header line, but we need to use

+anchor at the ends of the value. MP-470.
+
+rewrite: Ruleset functional MP-469
+
+--- 1.3.59 2013/07/12
+
+session_shared: negotiate init sz parameters.
+By default, session_shared will honor the paramters given by client.
+An alternative, but not implemented, algorithm would be to only
+re-use sessions with same sz parameters. This however, could reduce
+re-use of sessions a lot. Hence this, simple algorithm instead. The
+negotiation to a maximum sz values can be enabled by using
+   <init maximum-record-size="sz1" preferred-message-size="sz2"/>
+in configuration. This will make session_shared send those values
+to backends and use returned init values in negotaition to
+client before session_shared.
+
+session_shared: resolve result-set references.
+The reference is substitued with the query for old set if database
+match and query type is Type-1. If not the reference will issue a
+diagnostic.
+
+sort filter: relays RecordComposition including elementSet in use for
+search.
+
+http_client: better diagnostics
+
+http_client: disables HTTP redirect handling by default.
+It can be configured with max-redirects in configuration.
+
+--- 1.3.58 2013/06/12
+
+Fix loading of filters cql_rpn and sru_z3950 . Was broken by 1.3.57.
+
+--- 1.3.57 2013/06/12
+
+Make RouterChain and RouterXML part of public API (libmetaproxy).
+
+http_client: honor X-Metaproxy-Proxy as an alternative to
+the "proxy" configuration. Allows proxy to be set per HTTP request.
+
+sru_z3950: For SRU requests recognize x-client prefixes as a way
+to ingest "database parameters".. The suffix of x-client- serves
+as database argument name. Multiple may be given. For example:
+  http://path/db/?operation=searchRetrieve&x-client-user=a&x-client-password=b
+is turned into Z39.50 database
+  db,user=a&password=b
+
+--- 1.3.56 2013/05/27
+
+New filter present_chunk. This filter allows splitting of present requests into smaller chunks.
+
+New filter sd_remove, which replaces surrogate diagnostics with
+SUTRS records. This filter tries to deal with clients that breaks
+when receiving surrogate diagnostics.
+
+new filter http_client. Same role as z3950_client, but just for
+HTTP. Allows Metaproxy to operate as a HTTP proxy.
+
+New filter http_rewrite1, which serves as purpose on how to rewrite
+HTTP content with Metaproxy.
+
+Use libboost-system if available, because newer versions of libboost-threads
+requires libboost-system.
+
+Allow frontend_net to serve SSL/HTTPS, because we can specify a server
+certificate now.
+
+--- 1.3.55 2013/04/10
+
+zoom: Torus setting: authenticationMode which may hold values "basic"
+and "url".
+
+--- 1.3.54 2013/03/27
+
+configure: check for Libxslt support in YAZ and rely on definitions
+from yaz-config, rather than doing own xslt/xml2 checks.
+
+Allow timestamp format for log lines to be given with option -m
+for metaproxy. Similar to yaz-ztest/GFS option -m.
+
+Document log category 'line' for log filter.
+
+Solr configuration example in etc/config-solr.xml
+
+multi: do not mess with request package. For scan and search,
+database-names were modified and the request package was left with
+dangling pointers that caused a log filter to fail (request package
+inspected after multi was invoked).
+
+Documentation: fix id of metaproxy-config ref .
+
+Documentation: update for USEMARCON support.
+
+--- 1.3.53 2013/01/31
+
+record_transform: allow OPACXML to OPAC conversion
+
+zoom: document content-proxy
+
+zoom: document db parm content-{user,password}, torus_url. Also
+<torus auth_url="..> which makes zoom operate in authenticated mode
+via Torus lookup.
+
+--- 1.3.52 2012/11/30
+
+zoom: fix http://-check. SRU search broken in 1.3.51.
+
+--- 1.3.51 2012/11/15
+
+zoom: only append http:// for SRU if not already given . Makes it
+possible to use https-URLs.
+
+Use yazpp 1.4 or later due to new ABI.
+
+frontend_net: allow max package size to be specified. Controlled by
+attribute 'max_recv_bytes' of element 'port'.
+
+--- 1.3.50 2012/10/29
+
+For most generated diagnostics by filters, typically temporary
+system error, augment addinfo message with filter name.
+
+Add support for CentOS 6 packages.
+
+sru_z3950: interpret Z39.50 diagnostics part of Init Response.
+
+Add man page for metaproxy-config.
+
+--- 1.3.49 2012/10/18
+
+zoom: new config element passthru. This defines an element set that is
+passed verbatim to the backend in pz2 mode.
+
+auth_simple: allow both idPass and open auth. Also fix SEGV that could
+occur for open auth.
+
+--- 1.3.48 2012/10/08
+
+z3950_client: fix string handling for init diagnostics in the case where
+addinfo was absent.
+
+query_rewrite: no charset conversion for error queries. Avoid performing
+charset conversion for query conversion errors. The resulting Type-1
+query is invalid in this case.
+
+--- 1.3.47 2012/10/04
+
+For graceful stop (SIGUSR1), metaproxy will kill children processes.
+
+Log when metaproxy is invoked in test mode (-t).
+
+Log PID for each log message.
+
+multi: combine both NSDs and multiple NSDs into one (diagnostics).
+
+z3950_client: fixup multiple NSD's too. Like surrogate diagnostics,
+a (backend=target) is appended for each diagnostic so that can be
+determined the origin of error.
+
+multi: hideerrors also in use for present response.
+
+Solr example in zoom man page.
+
+Fix typo in query_rewrite config example.
+
+Log at least first non surrogate diagnostic. Instead of
+"Z_Records_multipleNSD"
+
+multi: Fix check for opt Records in present response. A SEGV could occur
+if a target did not return records and no diagnostics.
+
+--- 1.3.46 2012/09/24
+
+Yet another fix for graceful stop.
+
+--- 1.3.45 2012/09/12
+
+sru_z3950: relay surrogate diagnostics.
+
+--- 1.3.44 2012/09/10
+
+zoom: Honor extraArgs, strip # in zurl.
+
+multi: fix SEGV for scan. Reported by Rustam T. Usmanov.
+
+zoom: url_recipe allow %{var[reg]} substitutions.
+It's like ${var[reg]} but does URI component encoding as well.
+
+--- 1.3.43 2012/08/22
+
+RPM/Deb: require yazpp 1.3.2, because it fixes a missing close of
+non-keepalive HTTP sessions.
+
+http_file: allow zero size files (bug fix)
+
+Fix zoom schema: auth_url is optional
+
+--- 1.3.42 2012/08/20
+
+zoom: fix un-init memory (could result in SEGV at session close)
+
+frontend_net: handle X-Forwarded-For. This is stored in package.origin()
+and may be used in filters as usual.
+
+zoom: authentication via Torus lookup
+Enabled by new configuration setting: auth_url . If this is defined,
+the zoom module will contact Torus for auth/IP lookup and that will
+define realm to be used in session.
+
+--- 1.3.41 2012/08/10
+
+virt_db: Fix database name - first character we removed by mistake.
+Bug introduced in 1.3.40.
+
+--- 1.3.40 2012/08/06
+
+virt_db: Don't use "unix path" as database for Unix sockets.
+
+--- 1.3.39 2012/08/02
+
+z3950_client: Don't tamper with / in zurl - fixes problems
+using Unix sockets for backends.
+
+session_shared: fix integer overflow problem with hit count.
+
+session_shared: avoid long usage of cached queries.
+
+zoom: New database argument , torus_url to set URL of Torus
+record to be fetched.
+
+--- 1.3.38 2012/07/04
+
+Fixes for 'metaproxy reload' for RPM/Debian packages. 
+
+zoom: Allow rpn2cql conversion to be augmented with a properties file.
+Element rpn2cql can be specified per-target for the zoom filter.
+
+log: New category "line" which is a single-line log message with
+most important parts of a HTTP/Z39.50 request/response.
+
+--- 1.3.37 2012/06/01
+
+frontend_net: add facility to report live statistics about response
+times and current thread usage. The report is an XML document
+and is triggered for a specific URL path. This is set by <stat-req>
+in the configuration of frontend_net. By default this report is
+disabled (same as empty value for <stat-req>).
+
+Fix reload problem in init.d script for RPM/Debian. 
+The '/etc/init.d/metaproxy reload' in some cases would stop but not
+start metaproxy - effectively stopping the service.
+
+Don't display start log message when config testing (-t).
+
+zoom: avoid CCL message limit of 1K in ZOOM filter.
+
+--- 1.3.36 2012/05/10
+
+metaproxy init script reacts to reload which does graceful stop +
+start and is used by logrorate script.
+
+--- 1.3.35 2012/05/09
+
+Fixes for Windows compilation.
+
+Metaproxy daemon reacts to SIGUSR1 in which case it will leave
+existing sessions running but terminate the monitor process that is
+used in keepalive mode.
+
+Change start log message to 'metaproxy start'. Was 'Metaproxy start'
+before. Consistent with 'metaproxy stop' message.
+
+zoom: document zoom's proxy_timeout
+
+z3950_client: fixup addinfo for init response
+
+virt_db: return other diagnostic if init is rejected. Diagnostic 236:
+"Access to specified database denied" is returned, but only if init
+response from backend does not carry diagnostics already.
+
+multi: relays user info for first rejected target. The other-information
+field for init response for first rejected target is in common init
+response. This ensures that some backend init diagnostics are returned to
+the frontend.
+
+--- 1.3.34 2012/04/25
+
+frontend_log: extend logging (when message is given in config).
+
+--- 1.3.33 2012/04/25
+
+zoom: Fix check for proxy. Use diagnostic 1074 for proxy failures.
+
+--- 1.3.32 2012/04/24
+
+sru_z3950 filter passes through incoming Z39.50 requests again. Was
+not handled by mistake in Metaproxy versions 1.3.29, 1.3.30 and 1.3.31.
+
+--- 1.3.31 2012/04/24
+
+zoom: fixes for retry/proxy failover logic. More logging.
+
+--- 1.3.30 2012/04/23
+
+zoom: return addinfo="proxy failure" for proxy failures. This also
+changes the scheme for dealing with proxies a bit.  zoom now always
+do proxy check, even if there's no failover. Fortunately, that's not
+very expensive.
+
+zoom: Init rejected wo diagnostics maps to Bib-1:1014.
+Bib-1 1014, "Init/AC: Authentication System error", seems pretty
+generic. We don't know why the init would fail; IP, user, block IP, etc.
+sru_z3950 filter maps this to SRU diagnostic 3: "Authentication error".
+
+zoom: guess if invalid SRU response was an auth failure
+
+session_shared: disable session retry by default . Can be enabled by
+restart="true" in resultset section.
+
+--- 1.3.29 2012/04/18
+
+zoom: may read cf-proxy's config settings.
+This reduces manual configuration of the content proxy server host.
+The ZOOM module will use the old style session.proxyhost if "server"
+is given (deprecated) and use the new style proxyhost/session if
+"config_file" is in use.
+
+frontend_net: remove incoming requests that can not be handled
+Requests in queue for filter frontend_net are removed if client
+closes connection for the session and request is not yet handled.
+
+sru_z3950: serialize requests. This is to ensure that pipelined
+HTTP requests are handled properly.
+
+--- 1.3.28 2012/04/04
+
+New class, wrbuf, that wraps YAZ' WRBUF.
+
+--- 1.3.27 2012/03/30
+
+Metaproxy daemon is now running as user "metaproxy". This user is
+managed by package maintainer scripts. The user information is stored
+in /etc/metaproxy/metaproxy.user . 
+
+--- 1.3.26 2012/03/20
+
+New filter, sort, that allows sorting of XML records via Z39.50
+retrieval.
+
+Filter record_transform: USEMarcon support. For example:
+  <retrieval syntax="usmarc">
+     <backend syntax="unimarc" name="F">
+       <usemarcon stage1="/etc/usemarcon/uni2us/uni2us.ini"/>
+     </backend>
+  </retrieval>
+
+Filter multi: empty route pattern uses route as default.
+  That is
+   <target route="z3950.indexdata.com">z3950.indexdata.com</route>
+  may use the shorter notation
+   <target route="z3950.indexdata.com"/>
+
+Filter query_rewrite: use config path to locate XSLT.
+
+Filter frontend_net:  log statistics.
+If a custom message element in frontend_net configuration it makes
+the frontend_net filter produce a log entry whenever an operation
+is completed. The log is always written using yaz_log with the
+custom message given, the package ID (session ID) , the time
+the operation has been active (end-to-end) , the threads currently
+active/total and the size of the request input/output queues.
+
+query_rewrite: charset conversion of query terms.
+This is an optional feature. Enabled by element <charset> in
+configuration with attribute 'from' and 'to' that specifies
+from/to encodings. The default 'from' encoding is UTF-8.
+
+Filter record_transform: honor piggyback searches.
+
+Filter zoom: re-connect when database is reused.
+Re-connect is necessary if a connection is lost or a timeout occurs.
+If not, we'll be seeing zero hits, when we shouldn't.
+
