+
+## [9.3.3] - 2019-03-29
+### Added
+- Add asyn_reconnection test ([#502][pr-502])
+- Add .gitignore ([#522][pr-522])
+- Add Visual Studio 2017 compatibility. Appveyor now builds for Visual Studio 2017 in addition to all the previously 
+supported versions ([#533][pr-533])
+
+### Changed
+- Replace CORBA::string_dup calls with Tango::string_dup ([#474][pr-474])
+- Replace CORBA::string_free calls with Tango::string_free ([#539][pr-539])
+- Make it possible to remove dynamic attributes from delete_device() by moving the location where the device is removed 
+from the device list ([#518][pr-518])
+- Use python2 (if available) to run cxxtestgen ([#523][pr-523])
+- Switch to Travis Xenial infrastructure ([#516][pr-516])
+- Catch exceptions from unsubscribe_event() in DeviceProxy destructor ([#521][pr-521])
+- Improve install documentation ([#529][pr-529])
+- Install log4tango include files under *<install_prefix>*/include/tango/log4tango ([#517][pr-517])
+- Update Doxygen documentation ([#532][i-532], [#544][pr-544])
+- Update Debian 7 and Debian 8 Travis Docker files after Debian Wheezy end of life and jessie-updates removal 
+  ([#546][i-546], [#549][pr-549])
+
+### Fixed
+- Fix memory leak in get_device_property() on Windows when code compiled with Visual Studio 10 or older 
+([#439][i-439], [#488][pr-488])
+- Fix cxx_fwd_att occasional failure ([#384][i-384], [#428][i-428], [#493][pr-493])
+- Fix "Change event subscription blind to change events right after device server restart" issue 
+([#359][i-359], [#503][pr-503]). 
+**This bug fix may trigger the reception of 2 consecutive events having possibly the same attribute value 
+(but different timestamps) during the Device Server startup phase.**
+- Fix client crash in case of asynchronous write_attribute executed immediately after reconnection ([#502][pr-502])
+- Fix issue with dynamic attributes when a device is restarted on a device server exporting several devices which are 
+creating dynamic attributes ([#458][i-458], [#508][pr-508])
+- Fix uncaught DevFailed exception in DeviceProxy destructor in cxx_stateless_subscription test case when using 
+ZMQ 4.2.3 ([#514][i-514]). Since [zeromq/libzmq@edb4ca1][libzmq-c-edb4ca1], peer disconnection triggers zmq_disconnect 
+on a zmq socket. 
+Further zmq_disconnect calls for such socket and endpoint will fail with errno set to ENOENT. 
+The patch provided in [#520][pr-520] ignores such failure.
+- Fixed a broken dependency on generated Debian package ([5c74e8d][c-5c74e8d])
+- Fix appveyor.yml after appveyor windows image update ([#537][pr-537])
+- Fix event compatibility issues with device servers exporting Device_4 devices. Fix bug with Pipe, Data Ready and 
+Device Interface Change events. Fix event channel name issues in these different cases. ([#492][i-492], [#531][pr-531])
+- Fix WAttribute::rollback() for DevUshort WRITE attributes ([#541][i-541], [#542][pr-542])
+
+## [9.3.2] - 2018-09-12 [unstable]

+- Integrate Coveralls and Sonar ([#369][i-369], [#478][pr-478])
+
+### Changed
+- Tests: Split runner executable into several executables ([#275][i-275], [#476][pr-476]).
+- Doxygen: upgrade to doxygen 1.8.13
+
+## Removed
+- Disable log4tango benchmark tests.
+
+### Fixed
+- Fix memory leak in zmq_event_subscription_change() ([#457][i-457], [#460][pr-460])
+- Fix bug impacting device servers using dynamic attributes ([#458][i-458], [#459][pr-459])
+- Fix reconnection issues when a client subscribes to several events ([#455][i-455])
+- Fix some event compatibility issues with device server <= Tango 8 ([#456][i-456])
+- Fix event field in EventData structure passed to user's callback (broken in Tango 9.3.0 and 9.3.1)
+- Fix attribute name in EventData structure passed to user's callback for Attribute Config events
+- Fix a bug occurring when an event is pushed at the same time as an event (re)subscription occurs 
+([#484][i-484], [#485][pr-485])
+- Fix event name (EventData.event) passed to client's Callback after Tango 9 attribute reconnection ([#486][pr-486])
+- Fix some doxygen warnings
+
+## [9.3.1] - 2018-05-23 [unstable]
+### Changed
+- Add -pedantic for GCC/Clang and debug mode ([#441][pr-441]). **This change can generate 
+  errors with very old compilers (e.g. gcc 3.4.6) when compiling the lib debug 
+  version.** Please remove manually -pedantic flag in configure/CMakeLists.txt if
+  you need to compile the debug version on a very old compiler.
+- Generate static library ([#17][i-17])
+
+### Fixed
+- DServerSignal: Include errno header instead of trying to manually get the declaration right ([#441][pr-441])
+- Remove GNU_CXX definition for GCC/Clang ([#441][pr-441])
+- filedatabase.cpp: Remove stray semicolon ([#441][pr-441])
+- FileDatabase: Use correct format specifier for unsigned arguments to sscanf ([#441][pr-441])
+- EventConsumer::connect_event: Fix misleading indentation ([#441][pr-441])
+- PollThread: Fix multiline macro definitions ([#451][pr-451])
+- Fix compilation definitions ([#437][pr-437])
+- Replace asserts in EventConsumer::initialize_received_from_admin with exceptions ([#453][i-453])
+
+## [9.3.0] - 2018-05-04 [unstable]
+### Fixed
+- Fix FQDN events ([#423][pr-423], [#315][i-315])
+   Limitations:
+     - in case DeviceProxy is used for event subscription, client will get incorrect value 
+	 in the event callback if short domain name is used in env.TANGO_HOST 
+	 e.g. hzgc103 -> hzgc103.desy.de
+- Fix memory leak when pipe event is sent and there is no client ([#447][i-447],[#448][pr-448])
+- Set the ZMQ Receive Buffer High Water Mark only if it changes ([#444][i-444],[#445][pr-445]) 
+   to reduce the impact of a bug in ZMQ 4.2.0 and ZMQ 4.2.1 which was fixed in 
+   commit [zeromq/libzmq@edc770d][libzmq-c-edc770d].
+
+## [9.2.8] - 2018-03-29 [unstable]
+### Changed
+- Cmake release targets ([#438][pr-438]) 
+- **Install include files in <install_prefix>/include/tango directory instead of 
+   <install_prefix>/include**.
+
+### Fixed
+- Fix appveyor build
+
+## [9.2.7] - 2018-02-27 [unstable]
+### Added
+- **Use CMake** 
+- Set CMake minimum requirement to CMake 2.8.12 ([#422][pr-422])
+- Add DevVarBooleanArray operators ([#347][pr-347])
+- Add support for NaN and inf in device properties ([#360][i-360], [#362][pr-362],[ #371][pr-371])
+- Refactor DeviceAttribute code ([#394][pr-394]). DeviceAttribute::init_common_class_members() method is now private
+- Forwarded dynamic attributes ([#342][pr-342])
+- Build on Windows using CMake and setup appveyor CI ([#413][pr-413])
+- Enable Travis CI ([#375][pr-375], [#417][pr-417], [#418][pr-418], [#419][pr-419])
+- tango_config.h: Add clang detection ([#442][pr-442])
+- Doxygen: Add searchbar ([#432][pr-432])
+
+### Changed
+- DeviceAttribute::get_type() no longer throws an API_EmptyDeviceAttribute exception when the DeviceAttribute is empty.
+  It returns DATA_TYPE_UNKNOWN instead ([#393][pr-393], [#509][i-509]).
+   
+  **Warning! This change could lead to Segmentation fault** in code doing things like:
+```  
+    DeviceAttribute da;
+    da = device->read_attribute("AnAttributeWithINVALIDQualityFactor");
+    cout << "Type = " << Tango::CmdArgTypeName[da.get_type()] << endl;
+```
+  Please refer to [#510][i-510] for more details.
+- Improve ZmqEventSubscriptionChange command argin and argout descriptions ([355da96][c-355da96])
+- Generate files from IDL (**add a dependency to tango-idl repository. omniidl is required to be able to generate some 
+  files from  CORBA IDL**)
+- Get exception message from event callback ([#431][pr-431])
+- Add a map in MultiAttribute object to improve performances ([#424][i-424], [#430][pr-430])
+- A small Doxygen improvement - take version from cmake ([#436][pr-436])
+- Reduce event subscription sleeps on linux ([#415][pr-415]).
+
+**Warning**: There is no guarantee that after a successful call to subscribe_event() that a subscriber will receive all 
+the events it is interested in. In some situations, some important events might be missed if they occur between the 
+subscribe_event() call and the ZMQ subscription reception on the ZMQ publisher side, potentially leading to situations 
+where a client application might show out of date/incorrect values.
+- Tango 9 LTS fix[#395][i-395] (Inserting const C string in DeviceData) ([#396][pr-396])
+
+### Removed
+- Remove zmq.hpp ([#266][i-266], [#421][pr-421]). **Add a dependency to https://github.com/zeromq/cppzmq**
+
+### Fixed
+- Add missing event implementation with \_TG_WINDOWS\_ ifdef ([#349][i-349])
+- Fix [TangoTickets#3][tt-i3] (Events received with UNKNOWN data format and without values when subscribing from
+  a Tango 9 client to a Tango 7 server DevShort attribute)
+- Fix bug related to heartbeat endpoints which could eventually occur when the device server runs on a host with
+  multiple network interfaces ([36aca17][c-36aca17])

+- Fix bug leading occasionally to segmentation faults of Tango 9 device servers ([#398][pr-398])
+- Fix bug in event name when pushing an error event to IDL5 clients ([#400][pr-400])
+- Attribute: Don't treat an integer as an char* ([#403][pr-403], [#406][pr-406])
+- pointer-cast-size-mismatch attrgetsetprop.cpp:200 ([#339][i-339], [#406][pr-406])
