New MINOR release 01.04.00 Changes since 01.03.00: - Add data validity flag to TransferElement - Add writeDestructively() to TransferElement. This is implemented already by the ControlSystemAdapter but can currently not be used, since it is missing in the interface. - Fixes for the logical name mapping backend: - Fixed thread safetly for LNMBackendVariableAccessor - Fixed LNMBackendBitAccessor safety. Along side writing them through TransferGroup is also fixed (#48) - Fixed parsing map file multiple times - this also has reset the content of variables to its default values from the map file when obtaining a register accessor. - Fixed throwing incorrect logic_error when trying to obtain an accessor on a closed device without prior call to getRegisterCatalogue(): the catalogue was not filled in that case. - Muxed data accessor for NumericAddressedBackends: adjust default FixedPointConverter bit width according to actual register width. This fixes a minor regression introduced in the last release. - DummyBackend: minor performance optimisation - Changes to build environment
