<dl class="user"><dt><b>Project wide</b></dt><dd></dd></dl>
<ul>
<li>build system<ul>
<li>added new variable GBX_DISABLE_ALL for the cases where only a few targets need to be built.</li>
<li>cleaned up install directory definitions, all done in one place now.</li>
<li>clean up to be packaged for Fedora.</li>
</ul>
</li>
</ul>
<dl class="user"><dt><b>Updated libraries</b></dt><dd></dd></dl>
<ul>
<li>libGbxNovatelAcfr:<ul>
<li>Bugfix: matched GPS status/solution enums to Novatel's internal types, there were gaps due to reserved values before. Note: this will create mismatches with old log-files (not data, status/solution-type only)! (MichaelM, patch by Ian Mahon)</li>
</ul>
</li>
</ul>
<ul>
<li>libhokuyo_aist<ul>
<li>Bugfix: Errors in the way intensity data is retrieved have been fixed. (gbiggs, bug report by martimorta)</li>
<li>New feature: The example now has an option, -i, to get intensity data.</li>
</ul>
</li>
</ul>
<ul>
<li>libflexiport<ul>
<li>Bugfix: Don't redeclare timespec if it already has been on Windows. (gbiggs)</li>
</ul>
</li>
</ul>
<ul>
<li>libGbxUtilAcfr<ul>
<li>class History: API simplified and is rewritten for periodic storage of history (more suitable for computers which can be powered off abruptly.</li>
</ul>
</li>
</ul>
<h2><a class="anchor" id="gbx_doc_history_907">
Changes in Release 9.07</a></h2>
<dl class="user"><dt><b>Updated libraries</b></dt><dd></dd></dl>
<p>-libGbxSmartBatteryAcfr (tobi)</p>
<ul>
<li>improved robustness by encapsulating data of the oceanserversystem class and implementing access/set and check-for-empty functions</li>
<li>improved healthcheck functions</li>
<li>bug fix related to initialisation</li>
<li>improved exception and error handling</li>
<li>added a raw data record to the oceanserversystem data record useful for debugging</li>
</ul>
<ul>
<li>libflexiport<ul>
<li>The UDP port type now properly supports sending and receiving broadcast packets on all operating systems. (GeoffB)</li>
</ul>
</li>
</ul>
<ul>
<li>libGbxIceUtilAcfr:<ul>
<li>Changed names in <a class="el" href="buffer_8h_source.html">buffer.h</a> to make it more intuitive, fixed comments (AlexB).</li>
<li>Timer class: added constructor with non-zero elapsed time (alexm)</li>
<li>Thread class: now derives from <a class="el" href="classgbxutilacfr_1_1Stoppable.html" title="An abstract interface class representing an stoppable activity.">gbxutilacfr::Stoppable</a>. No changes in user code are requried. (alexm)</li>
<li>Function checkedSleep() is defined in terms of the new light interface class <a class="el" href="classgbxutilacfr_1_1Stoppable.html" title="An abstract interface class representing an stoppable activity.">gbxutilacfr::Stoppable</a>. No changes in user code are required. (alexm)</li>
<li>Implemented store::peek() (AlexB)</li>
</ul>
</li>
</ul>
<ul>
<li>libGbxUtilAcfr:<ul>
<li>Status class: removed SubsystemStalled from the list of health types for a subsystem. The stall condition now needs to be defined as part of the state of the monitor. (alexm)</li>
<li>Added SubHealth class: a delegator which has access to health function of one subsystem. (alexm)</li>
<li>Added Stoppable class: a light interface class representing stoppable activities. (alexm)</li>
</ul>
</li>
</ul>
<ul>
<li>libhokuyo_aist<ul>
<li>New known-to-work models. The full list is now: URG-04LX, UBG-04LX, UHG-08LX and UTM-30LX. As usual, other models that conform to the protocol should also work. (GeoffB)</li>
<li>Improvements to the SCIP protocol version checks, giving faster and more reliable startups. (GeoffB)</li>
<li>Implemented a workaround for a bug in the UTM-30LX firmware. (GeoffB)</li>
<li>Better baud rate support. (GeoffB)</li>
</ul>
</li>
</ul>
<dl class="user"><dt><b>Project Wide</b></dt><dd></dd></dl>
<ul>
<li>Build system<ul>
<li>Added a hook in the CMake setup to allow building Gearbox as part of a bigger "super-project". Default behavior is not modified. (tobie,alexm)</li>
<li>Changed format style of CMake files. Standard functions are low-case. Custom macros are upper case. "Local" variables are low-case. "Global" and cache variables are upper-case. (alexm)</li>
<li>Added 4 advanced CMake variables to let user control what gets installed and what not. All are set to TRUE by default. To disable installation, set a variable to FALSE on the command line: 'cmake -DGBX_INSTALL_HEADERS=false'. The variables are:<ul>
<li>GBX_INSTALL_HEADERS</li>
<li>GBX_INSTALL_SHARED_FILES</li>
<li>GBX_INSTALL_EXAMPLES</li>
<li>GBX_INSTALL_PKGCONFIGS</li>
</ul>
</li>
<li>New versioning scheme for libraries. Each individual library has its own so version, which can be incremented independently of other libraries at the project as a whole. This allows users to check the API version of the library they are interested in, improving dependency checks for users of Gearbox.</li>
</ul>
</li>

</ul>
</li>
</ul>
<ul>
<li>libGbxUtilAcfr<ul>
<li>Changed interface for Tracer:<ul>
<li>when querying verbosity, default destination argument is 'ToAny' (AlexB).</li>
<li>moved trace type and destination enums out of the class into the namespace (alexm)</li>
<li>added optional 'localOnly' parameter to all Tracer output function, i.e. info(), warn(), error(), debug(). This is to allow the use of Tracer for tracing network problems (otherwise a trace of a network problem will lead to another trace, etc) (alexm)</li>
</ul>
</li>
<li>Changed implementation of TrivialTracer to allow multiple levels of tracing verbosity (AlexB).</li>
<li>Changed interface for Status:<ul>
<li>status of subsystems is described in two orthogonal dimensions: state and health. (alexm)</li>
<li>added infrastructure state to the component status and functions to set it. (alexm)</li>
<li>added message() which only changes the human-readable message (alexm)</li>
