+
+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
+
+zoom: content-{user,password,proxy} are passed on to content proxy
+system and takes precedence over user,password,proxy .
+
+sru_z3950: SRU extra argument x-log-enable=1 enables a search response
+with a log element including log material from children filters. At
+this point, only the zoom filter uses this log facility. It will
+eventually be used by other filters as well. In particular it might be
+useful for this feature to track all filters in used during a search.
+
+zoom: for x-log-enable=1, APDUs sent by ZOOM C, records as received
+and queries as they are manipulated are logged.
+
+zoom: extend addinfo with native diagnostics. Diagnostics as received
+by ZOOM C are put into addinfo - including ZOOM, HTTP, SRU and Bib-1
+diagnostics. This indicates both a backend diagnostic and the original
+form.
+
+zoom: default urlRecipe value is ${md-electronic-url}
+
+zoom: target profile setting sruVersion is recognized.
+
+--- 1.3.17 2011/11/17
+zoom: log target profile record fetched (AKA Torus).
+
+--- 1.3.16 2011/11/17
+
+Change target profile parameter CfSubDb to CfSubDB.
+
+--- 1.3.15 2011/11/12
+
+zoom: bug fix: realm was relayed to CF targets by mistake (realm only
+makes sense to the zoom module itself).
+
+--- 1.3.14 2011/11/11
+
+zoom: realm may be given as part of database.
+
+--- 1.3.13 2011/10/26
+
+Fix Origin class assigment method; was removd by mistake in 1.3.12.
+
+--- 1.3.12 2011/10/26
+
+zoom: database args x-name=value are passed through to backend database.
+
+SRU filter: user may specify session ID that is passed to log entries
+that follows. It is specified by using x-session-id in the SRU arguments.
+
+zoom: fix null pointer reference which would occur for bad url parameter
+inside "torus" or if url was not given.
+
+--- 1.3.11 2011/09/09
Fix bug in filter session_shared where sessions would not expire
properly (session ttl). This in turn could make the target close the
connection before expected and session_shared would return diagnostic
