- Add ``skip_by_annotation`` to :meth:`mne.io.Raw.filter` to process data concatenated with e.g. :func:`mne.concatenate_raws` separately. This parameter will default to the old behavior (treating all data as a single block) in 0.15 but will change to ``skip_by_annotation='edge'``, which will separately filter the concatenated chunks separately, in 0.16. This should help prevent potential problems with filter-induced ringing in concatenated files, by `Eric Larson`_

- Make the goodness of fit (GOF) of the dipoles returned by :func:`mne.beamformer.rap_music` consistent with the GOF of dipoles returned by :func:`mne.fit_dipole` by `Alex Gramfort`_.

- Make function ``mne.io.eeglab.read_events_eeglab`` public to allow loading overlapping events from EEGLAB files, by `Jona Sassenhagen`_.
- :func:`mne.find_events` ``mask_type`` parameter will change from ``'not_and'`` to ``'and'`` in 0.16.
- Instead of raising an error, duplicate channel names in the data file are now appended with a running number by `Jaakko Leppakangas`_
- :func:`mne.io.read_raw_edf` has now ``'auto'`` option for ``stim_channel`` (default in version 0.16) that automatically detects if EDF annotations or GDF events exist in the header and constructs the stim channel based on these events by `Jaakko Leppakangas`_
- :meth:`mne.io.Raw.plot_psd` now rejects data annotated bad by default. Turn off with ``reject_by_annotation=False``, by `Eric Larson`_
- :func:`mne.set_eeg_reference` and the related methods (e.g., :meth:`mne.io.Raw.set_eeg_reference`) have a new argument ``projection``, which if set to False directly applies an average reference instead of adding an SSP projector, by `Clemens Brunner`_
- Deprecate ``plot_trans`` in favor of :func:`mne.viz.plot_alignment` and add ``bem`` parameter for plotting conductor model by `Jaakko Leppakangas`_
- ``mne.beamformer.tf_lcmv`` now has a ``raw`` parameter to accommodate epochs objects that already have data loaded with ``preload=True``, with :meth:`mne.Epochs.load_data`, or that are read from disk, by `Eric Larson`_

- Add ``patterns=False`` parameter in :class:`mne.decoding.ReceptiveField`. Turn on to compute inverse model coefficients, by `Nicolas Barascud`_
- The ``scale``, ``scale_time``, and ``unit`` parameters have been deprecated in favor of ``scalings``, ``scalings_time``, and ``units`` in :func:`mne.viz.plot_evoked_topomap` and related functions, by `Eric Larson`_
- ``loose`` parameter in inverse solvers has now a default value ``'auto'`` depending if the source space is a surface, volume, or discrete type by `Alex Gramfort`_ and `Yousra Bekhti`_
- The behavior of ``'mean_flip'`` label-flipping in :meth:`mne.extract_label_time_course` and related functions has been changed such that the flip, instead of having arbitrary sign, maximally aligns in the positive direction of the normals of the label, by `Eric Larson`_
- Deprecate force_fixed and surf_ori in :func:`mne.read_forward_solution` by `Daniel Strohmeier`_
