  <dc:description>What's Changed since v0.11.0
The main changes in this release are related to expanding the data model to include DL2 and the computation of DL2 parameters.   This also required changing the units of some DL1 parameters from the CameraFrame to the TelescopeFrame to make them easier to compare between telescopes, which  includes an overhaul of how the HillasReconstructor works (supporting both frames as input), and adds  include a new Component ShowerProcessor that generates DL2(a) information.  The data model was expanded to include DL2 and to support a more general InstrumentDescription serialization.  DL1Writer was refactored into a general DataWriter that  writes the full data model. TableLoader provides a user interface to load all events at once from ctapipe output files, joining them as needed, which is useful for benchmarking.
The ctapipe-stage1 tool was removed and replaced with  the more general ctapipe-process, which can now handle any transformation from R0 to DL2a, depending on what configuration file it is given.  A ctapipe-quickstarttool was added to generate some starting config files, and a ctapipe-fileinfo tool to show file header information for any files written by ctapipe.
