- Updated documentation of "channel_builder"
- Updated documentation of "parameter_set"

v1.0.16-244
- Bugfix: Output XPR values did not match the give XPR
- Bugfix: channel.get_version crashed when called on a channel array
- Added private function "generate_initial_xpr" to channel builder

v1.0.12-231
- Bugfix: MATLAB did not free memory upon clearing an object.

v1.0.11-219
- Update: Added optional function to "array.import_pattern" to calibrates the phase of the pattern. A common phase offset on both polarizations is detected and removed.

- Update: Added option to calculate the phase in "layout.power_map".
- Update: "layout" now throws an error if Tx or Rx names are not unique.
- Feature: Added new method for the polarization calculation. "simpar.use_polarization_rotation = 3" now uses Pol-Rot. for the geometric pol. and WINNER method for the NLOS components.

v1.0.10-218

- Added unit test for channel merger

v1.0.8-194
- Bugfix: Manual parameter inferface could apply path gain twice

v1.0.7-191
- Bugfix: Deleys could be initialized wrongly when setting drifting precision to 2 or 3
- Set LOS-scatter radius in all config-files to 0 (this feature was not part of WINNER and needs further testing)

v1.0.6-174
- Bugfix: channel_builder.get_los_channels ignored array geometry
- Bugfix: fixed a bug, which occurred in the spline_2d function in case there is only a single user and the subset of the maps is only 4 samples wide, by increasing the size of the map subset by a sample in each direction
- Changed structure in "simulation_parameters" class definition

v1.0.5-161
- Bugfix: Default Tx names now have the format "Tx01" instead of "Tx1". This caused the channels to be out of order when morae then 10 Txs were used.

v1.0.4-153
- Feature: Speed profiles are now processed automatically in "layout.get_channels"

v1.0.3-152
- Feature: Manual Parameter Interface

- Improved comments and variable names in "channel.merge"
- Moved SF-scaling into "parameter_set.get_pl"
- Moved 2D spline interpolation in "parameter_set" into a separate subfunction
- "parameter_set" now uses the same spline interpolation for "update_parameters" and "get_sf_profile"

v1.0.2-146
- Feature: Added support for short names in config files.

v1.0.1-145
- Bugfix (major): K-Factor variations also scale shadow fading (error in KF-implementation)
- Bugfix (minor): WINNER path loss formula now uses ground distance
- Bugfix (minor): WINNER path loss formula now ignores MT heights lower than 1.5 m (no NaNs in output anymore)
- Bugfix (minor): layout.get_channels ignored "show_progress_bars"
- Feature: Disabling track names in "layout.visualize" is now possible (less clutter)
- Added config-files from WINNER+ and MIMOSA

v1.0.0-139
