+--- 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.
+
+--- 1.3.25 2012/02/29
+
+zoom: Change scheme for dealing with content proxy URLs. The module
+now has its own common XSL transform that is enabled by record_xsl
+attribute in the configuration. This XSL gets parameter cproxyhost
+that holds the host for the content proxy session . The genearted-url
+is created only if urlRecipe is enabled. In previous version default
+value of urlRecipe was ${md-electronic-url}; it is now empty and
+disabled by default. Also generated-url no longer includes the content
+proxy host. Content proxying URLs is supposed to the handle in the record_xsl
+stylesheet.
+
+zoom: new setting timeout that specifies timeout for outgoing Z39.50/SRU
+connections. Default value is 40 (seconds).
+
+zoom: tune CCL to Z39.50 diagnostics mapping. Throw Bib-1: 108
+"Malformed query" for syntax errors and related ones; throw
+Bib-1: 3 "Unsupported search" for everything else. Details from
+the CCL parser is provided as additional-info.
+
+multi: new setting hideerrors that makes multi only relay diagnostics
+to a client if all backends fail.
+
+--- 1.3.24 2012/02/23
+
+zoom: empty ccl_map field-mappings disables CCL map.
+
+zoom: fix Explain search that could return error if session was
+re-used.
+
+--- 1.3.23 2012/02/10
+
+zoom: returns Explain records for database IR-Explain---1. The
+target profile records are converted to Explain records via XSLT.
+
+session_shared: make error recovery configurable. Whether a search
+is restarted on errors or not, is configurable by attribute "restart"
+in element "resultset" in configuration.
+
+session_shared: only relay init for first request. session_shared, for
+each backend class, now only relays first init request (rather than all).
+The module only needs to save init response info once. This avoids the
+need to check for session max.
+
+--- 1.3.22 2012/02/02
+
+zoom: fix memory leaks.
+
+session_shared: maximum number of sessons is configurable. Default
+value is 100. Result-sets for backends without named result sets are
+only re-used if databases is identical for a search. This is under the
+assumption that performance may suffer for those backends when
+changing the database for each search.
+
+multi: combines diagnostics from all backends. All diagnostics from
+backends are combined into multiple non-surrogate diagnostics; rather
+than just one diagnostic from first backend.
+
+--- 1.3.21 2011/12/27
+
+zoom: relay realm to cproxy parameter file.
+
+Configuration: Allow filter collection element inside route. This
+makes it possible to include multiple filters at once.
+
+zoom: nocproxy also disables urlRecipe.
+
+--- 1.3.20 2011/12/21
+
+zoom: return diagnostic if CQL sortby conv fails. Diagnostic Bib-1 214
+"Illegal sort relation" is returned. Gets translated to SRU diagnostic
+90: "Unsupported direction value".
+
+zoom: honor database argument nocproxy. This disables creating a content
+connector session (for non-CF targets, usually) and also relays nocproxy
+as database argument to a CF target.
+
+--- 1.3.19 2011/12/16
+
+zoom: Multiple proxy hosts may be given for proxy rich database
+parameter. List is comma separated.
+
+http_file: decodes URI paths properly. Does not return 404: not found
+if no prefix are matches. Instead packages are passed on.
+
+--- 1.3.18 2011/12/08
