+
+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

+
+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

+--- 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"

+
+--- 1.3.45 2012/09/12
