GTR version matrix
==================
Given a version number ``MAJOR.MINOR.PATCH``, the ``MAJOR`` part tracks the GTR phase implemented.
The following matrix shows these correspondences:

+---------+-----------------------------+
| Release |           GTR ver           |
| train   |                             |
+=========+=============================+
| 0.0.9   | Un-precise GTR phase-1a     |
|         | (diffs explained below)     |
+---------+-----------------------------+
| 0.1.x   | GTR phase-1a                |
|         | (TODO)                      |
+---------+-----------------------------+
| 1.x.x   | GTR phase 1b [TDB]          |
+---------+-----------------------------+


Known deficiencies
==================
* (!) Driveability-rules not ordered as defined in the latest task-force meeting.
* (!) The driveability-rules when speeding down to a halt is broken, and human-drivers should improvise.
* (!) The ``n_min_drive`` is not calculated as defined in the latest task-force meeting,
  along with other recent updates.
* (!) The ``n_max`` is calculated for ALL GEARS, resulting in "clipped" velocity-profiles,
  leading to reduced rpm's for low-powered vehicles.
* Clutching-points and therefore engine-speed are very preliminary
  (ie ``rpm`` when starting from stop might be < ``n_idle``).

.. _todos-list:

TODOs
=====
* Add cmd-line and UI front-ends.
* Use a model-explorer to autocomplete excel-cells.
* Automatically calculate masses from H & L vehicles, and regression-curves from categories.
* wltp_db: Improve test-metrics with group-by classes/phases.
* model: Enhance model-preprocessing by interleaving "octapus" merging stacked-models
  between validation stages.
* model: finalize data-schema (renaming columns and adding ``name`` fields in major blocks).
* model/core: Accept units on all quantities.
* core: Move calculations as class-methods to provide for overriding certain parts of the algorithm.
* core: Support to provide and override arbitrary model-data, and ask for arbitrary output-ones
  by topologically sorting the  graphs of the calculation-dependencies.
* build: Separate wltpdb tests as a separate, optional, plugin of this project (~650Mb size).

Changelog
=========

v0.0.9-alpha.4 (5-Oct-2015)
----------------------------
Same algo as `alpha.3` but with corrected engine-speed for idle.
It is used for reports and simulation run by JRC to build the CO\ :sub:`2`\MPAS model,
but still not driveable due to downshifting to 1st-gear when stopping to standstill.

* core, model: Possible to define different `n_min_drive` & `f_safety_margins` per gear.
* core: Add function to identify gear-ratios from experimental engine-runs.
* excel, tests: Add ExcelRunner TCs.
* Updated ``jonschema`` dep 2.5.0.


v0.0.9-alpha.3 (1-Dec-2014)
---------------------------
This is practically the 1st public releases, reworked in many parts, much better documented,
continuously tested and build using TravisCI, with on-the-fly generated diagrams as metrics,
BUT the arithmetic results produced are still identical to v0.0.7, so that the test-cases and
metrics still describe that version, for future comparison.

* Use CONDA for running on TravisCI.
* Improve ExcelRunner.
* docs and metrics improvements.
* ui: Added Excel frontend.
* ui: Added desktop-UI proof-of-concept (:class:`wltp.tkui`).
* metrics: Add diagrams auto-generated from test-metrics into generated site (at "Getting Involved" section).

Noteworthy or *incompatilble* changes
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
* Code:
    * package ``wltc``  --> ``wltp``
    * class ``Experiment``    --> ``Processor``
* Model changes:
    * ``/vehicle/mass`` --> (``test_mass`` and ``unladen_mass``)
    * ``/cycle_run``: If present, (some of) its columns override the calculation.
* Added Excel front-end.
* Added *Metrics* section in documents whith on-the-fly generated diagrams comparing and tracking
  the behavior of the algorithm.
* Now the Eclipse's PyDev-project files are included only as templates; copy them and
  remove the `eclipse` prefix before importing project into Eclipse/Liclipse.



v0.0.9-alpha.1 (1-Oct-2014)
---------------------------
* Backported also to Python-2.7.
* model, core: Discriminate between :term:`Test mass` from :term:`Unladen mass`
  (optionally auto-calced by ``driver_mass`` = 75(kg)).
* model, core: Calculate default resistance-coefficients from a regression-curve (the one found in Heinz-db).
* model, core: Possible to overide WLTP-Class, Target-V & Slope, Gears if present in the ``cycle_run`` table.
* model: Add NEDC cycle data, for facilitating comparisons.
* tests: Include sample-vehicles along with the distribution.
* tests: Speed-up tests by caching files to read and compare.
* docs: Considerable improvements, validate code in comments and docs with *doctest*.
* docs: Provide a http-link to the list of IPython front-ends in the project's wiki.
* build: Use TravisCI as integration server, Coveralls.io as test-coverage service-providers.
* build: Stopped .EXE distribution; need a proper python environment.
