0.8 (2016-12-21)
----------------

- Added a `threads` parameter to `plot_fit` and `plot_samples` that set the
  number of cores to use in computing model samples for plotting.
- Added a new model for EBL absorption based on the tables of Dominguez et al.
  2011.

Bug fixes
^^^^^^^^^
- Updated to use new ``emcee`` autocorrelation API in version 2.2.
- Fixed sherpa models string representation.

0.7.1 (2016-02-04)
------------------

- Packaging bugfix

0.7 (2016-02-04)
----------------

- The ``InverseCompton`` class can now compute IC on arbitrary seed photon
  fields passed as arrays.
- ``plot_fit`` and ``plot_data`` have new options (``errorbar_opts`` and
  ``ulim_opts``) to control the properties of spectral flux points and
  upper-limits.
- There is a new table model class in ``naima.models.TableModel``.
- Added ``corner`` (former ``triangle_plot``) as a dependency.

0.6.1 (2015-10-29)
------------------

- Performance improvements to the memoize logic that result in 10% or higher
  improvement in model execution time.

0.6 (2015-09-10)
----------------

- Medians and associated errors are now shown with a precision corresponding to
  a single significant digit in the errors (except when the leading digit is 1,
  when two significant digits are shown). Note that they are still saved with
  full precision to the result tables.
- There is a new GUI tool for interactive model fitting:
  ``InteractiveModelFitter``, which can be accessed directly or through the
  ``interactive`` argument of ``get_sampler`` prior to a sampling run.
- Sampling run results can be saved and retrieved for later analysis or archival
  with the new functions `naima.save_run` and `naima.read_run`.
- The individual contributions to the total Inverse Compton spectrum of the
  different seed photon fields can now be accessed through the ``seed`` argument
  of the ``InverseCompton.flux`` and ``InverseCompton.sed`` functions.

Bug Fixes
^^^^^^^^^

- ``save_diagnostic_plots`` now turns matplotlib interactivity off, so the plots
  are only saved and not shown.
- The ``group`` column is now preserved if a data table is validated more than
  once.

0.5 (2015-08-05)
----------------

- ``save_results_table`` now saves the maximum log likelihood and ML parameters
  of the sample.
- Update ``astropy_helpers`` to 1.0.2 and require astropy >= 1.0.2 to ensure
  pickleable Tables.
- Internal data is a QTable instead of a dict.
- When multiple input spectra are used, they are now plotted with different
  colors and markers.
- Now doing the prefit with a minimizer that allows for relative tolerance
  termination: in general prefit will be faster.
- Add ``e_range`` and ``e_npoints`` parameters to ``plot_fit`` to allow
  computing the model samples for a wider energy range that the observed
  spectrum (or at energies between data sets, such as X-ray and gamma-ray)
- Added ``plot_corner`` as a thin wrapper around ``triangle.corner`` with ML
  parameter plotting.

0.4 (2015-03-19)
----------------

- All models have a cache of length 10 so that the output is not computed when
  the parameters have not changed. It can be turned off through the ``_memoize``
  attribute of the models.

Bug Fixes
^^^^^^^^^

- Fixed concatenation of UL and CL in ``validate_data_table``.

0.3 (2015-02-19)
----------------

- Added an option to save the distribution properties of scalar blobs when
  saving results table: option ``include_blobs`` of ``save_results_table``.
- A new method for radiative classes allows to renormalize the particle
  distributions to a given energy content in particles. See ``set_We`` and
  ``set_Wp`` in leptonic and hadronic classes, respectively.
- The default FIR and NIR photon fields for `naima.InverseCompton` have been set
  to the GALPROP values at a galactic radius of 6.5 kpc.
- Require astropy >= 1.0.

Bug Fixes
^^^^^^^^^

- Fixed sed conversion of residuals [#69]
- Fixed ``plot_data`` so it can take lists of data_tables.

API Changes
^^^^^^^^^^^

- The name of the ``table_format`` parameter of ``save_results_table`` has been changed
  to ``format`` for consistency with `astropy.io.ascii`.

0.2 (2015-02-10)
----------------

- Refactored sherpa models to use parent SherpaModelECPL class [#62]
- Added a data_sed flag to get_sampler to select whether to convert all data
  tables to SED or choose format of first data tables when providing multiple
  data tables.
- Added support for  a ``flux_ul`` column in input data tables.
- Added a method to estimate magnetic field: `naima.estimate_B`.
- Added the option to perform an optimization of the parameters before the MCMC
  run: see option ``prefit`` in `naima.get_sampler`.
- Convert between SED and differential fluxes automatically if the model and
  data physical types do not match.
- Add blob_labels parameter to save_diagnostic_plots.

Bug Fixes
^^^^^^^^^

- Fix sherpa models guess() for integrated datasets.
- Only complain about CL when there are ULs at a different CL.
- Fix parsing of string upper limit columns in Python 3.
- Use old energy unit when plotting a new data set onto a figure [#64]
- Show ordinate units when plotting blobs without spectral data.

API Changes
^^^^^^^^^^^

- module sherpamod is now sherpa_modules.


0.1 (2015-02-02)
