+--- 1.1.6 2010/06/30
+
+session_shared: ensure backend session is closed if init rejected
+is received.
+
+z3950_client: fix NULL ptr reference that could occur if two clients
+connected concurrently and if max-sockets was in effect.
+
+--- 1.1.6 2010/06/21
+
+Fix bug 3497 - Metaproxy unstable while stopping.
+
+Fix bug 3495 - SEGV in SRU filter.
+
+--- 1.1.5 2010/06/15
+
+Filter multi throws diagnostic 'Present Out of Range' when
+appropriate - rather than returning 0 records.
+
+Filter virt_db: fix bad result reuse. Could happen if a result
+was overriden and a backend did not supported named result sets.
+
+--- 1.1.4 2010/05/11
+
+Filter log: category access logs diagnostics even if searchStatus
+or presentStatus is 'success'.
+
+--- 1.1.3 2010/04/21
+
+The SRU to Z39.50 filter does repeated Z39.50 present requests
+to fetch all records. Needed when a Z39.50 server returns partial
+results (due to message size limits).
+
+--- 1.1.2 2010/03/18
+
+Metaproxy now kills all child processes that are spawned by
+modules (in case of fork, exec).
+
+--- 1.1.1 2010/01/28
+
+Debian package now installs /etc/metaproxy/metaproxy.xml which
+includes all XML files /etc/metaproxy/filters-enabled .
+The include facility uses YAZ' yaz_xml_include_simple (YAZ 4.0.1).
+
+--- 1.1.0 2010/01/20
+
+Package based on YAZ version 4 and YAZ++ 1.2.0. It now includes a
+development package to facilitate 3rd party Metaproxy modules.
+
+--- 1.0.23 2010/01/04
+
+Filter virt_db: Close backend filter session when Init rejected is received
+from it (in which case it's not really closed yet). This will ensure we don't
+run out of resources such as FDs in this case.
+
+sru_z3950 filter: Accept any database (including those not listed).
+
+--- 1.0.22 2009/12/03
+
+Prepare for 64-bit YAZ. yazproxy will still work with YAZ++ 1.1.4 or
+later which means YAZ 3.0.47 or later.
+
+--- 1.0.20 2009/11/19
+
+For filter virt_db, the database is a glob pattern and the virtual
+database sections are consulted in the order given.
+
+--- 1.0.19 2009/07/08
+
+For filter multi, the target (for routing) may be given as a glob-pattern.
+
+More documentation for filters virt_db and multi.
+
+Update schema to allow for no database in sru_z3950 filter.
+
+--- 1.0.18 2009/06/30
+
+Added limit filter to put sleep (penalty) for heavy use.
+
+Filter frontend_net may be configured to limit the number of new connections
+from same IP to some value (connect-max).
+
+Fixed the load_balance filter.
+
+--- 1.0.17 2009/06/16
+
+Fix path for metaproxy executable for Debian init.d script.
+
+--- 1.0.16 2009/06/10
+
+SRU to Z39.50 filter honors x-username and x-password. If only
+x-username is given that translates to open authentication (Z39.50v2). If
+both x-username and x-password is present that translates to idPass
+authentication (Z39.50v3).
+
+New facility to change current working directory (-w).
+
+Update to upstream skeleton of init.d script. Should fix bug #2619.
+
+Filter session_shared now caches records (used to only cache connections
+and result sets).
+
+Filter session_shared now invalidates a Z39.50 session if a server
+returns -1 hits. This facility was also part of yazproxy and gets around
+a bug in Voyager-based Z39.50 servers.
+
+--- 1.0.15 2008/11/18
+
+Fixed reference counting bug in Z39.50 client module (could cause SEGV).
+
+--- 1.0.14 2008/06/09
+
+Fixed the value of SRU record schema in searchRetrieve response. It was set
+to a fixed value of "dc" before.
+
+Serialize identical SRU requests. This is useful if HTTP client software
+fires identical requests against metaproxy.
+
+Allow Z39.50 target to be specified for SRU requests by using SRU extra
+parameter x-target. Allows SRU to contact arbitrary Z39.50 targets and
+avoid static configuration. This facility is handled by the sru_z3950 module
+and the z3950_client module.
+
+Allow maximum number of sockets to be used for a Z39.50 client by the
+use of SRU extra parameter x-max-sockets. This facility is handled by the
+sru_z3950 module and the z3950_client module.
+
+--- 1.0.13.1 2008/02/29
+
+Simplified check for Boost libraries.
+
+--- 1.0.13 2008/02/29
+
+First Debian package.
+
+The sru_z9350 filter now recognizes SRU parameter z-target as being
+a ZURL of the form host/database .
+
+Mergetype may be specified for filter 'multi'.
+
+--- 1.0.12 2007/09/19
+
+Fixed problem in Makefile WRT library specifictions. This could produce
+linker errors (when they should not happen).
+
+Fixed bug #1341: MetaProxy returning different results. Problem was that
+fix-up of record database did not normalize the database name.
+
+Documentation updates for Windows compilation.
+
+--- 1.0.11 2007/06/14
+
+Fixed problem with logfile being truncated.
+
+--- 1.0.10 2007/05/23
+
+Fixed bug #1136: Access rights not enforced.
+
+Extension for log module. The log category 'access' logs more details.
+New category 'user-access' added which is simlar to 'access' but adds
+the Z39.50 user as for all entries in a session.
+
+Switched to GPL v2.
+
+Added support for configurable default/force target/vhost for module Z39.50
+client module.
+
+--- 1.0.8 2007/01/25
+
+Implemented filter, session_shared, which optimizes usage of Z39.50
+sessions and result sets.
+
+New filter, record_transform, which converts MARC/XML records.
+
+New filter, sru_z3950, which converts SRU to Z39.50 packages.
+
+New filter, load_balance, in development.
+
+New filter, zeerex_xplain.
+
+XML framework for config files started.
+
+Master RelaxNG Compact schema's are found in xml/schema/*.rnc,
+RelaxNG XML schemas and XML Schema's are generated from RNC syntax.
+XML config files are checked against RNG and XML Schema's.
+
+XSLT transformation framework added in xml/xslt/*.xsl, consisting mainly of
+LOC Marc21 stylesheets found at http://www.loc.gov/marcxml/xslt.
+Added stylesheet explain2cqlpqftxt.xsl which transforms a standard SRU ZeeReX
+explain record to YAZ CQL-to-PQF text config file.
+
+--- 1.0.7 2006/11/07
+
+Added 'timeout' setting for filter frontend_net which specifies the number
+of seconds a session is idle before it is closed. Default timeout is
+300 (5 minutes).
+
+--- 1.0.6 2006/07/07
+
+Database name in records returned set for virt_db/multi filters.
+
+Filter session_shared now functional.
+
+Log filter can be configured to write to a given file using 'filename'
+element. Also information category can be specified with 'category'. If
+filename is omitted, the log filter writes to stdout. See etc/config5.xml
+for example.
+
+--- 1.0.5 2006/05/16
+
+Fixed compilation on Windows.
+
+--- 1.0.4 2006/05/16
+
+Added documentation for the hidenavailable option for the multi filter.
