Release Notes

Important

pulse2percept 0.5 will be the last release to support Python 2.7 and 3.4. pulse2percept 0.6+ will require Python 3.5 or newer.

v0.6.0 (2019)

Highlights:

• New API (PR #96)
• New models: ScoreboardModel (PR #96), AxonMapModel (PR #96).
• New build process: Compile code and run tests via Makefile (PR #96).
• Documentation now includes a tutorial, user guide, developer’s guide, and a gallery.
• Python 2.7 and 3.4 are no longer supported (PR #96).

New features

• A visual prosthesis is now considered a ProsthesisSystem consisting of an ElectrodeArray and optionally a Stimulus (PR #96).
• A Stimulus can be created from various source types, such as scalars, NumPy arrays, dictionaries, and TimeSeries objects.
• ElectrodeArray now stores electrodes in a dictionary (issue #74).

API changes

Backward-incompatible changes

• The Simulation object has been removed. Please directly instantiate a model instead.

Deprecation removals

• pulse2percept.Simulation: directly instantiate a model instead
• pulse2percept.retina: use models instead
• pulse2percept.files: use io instead

v0.5.0 (2019)

Highlights:

• New pulse2percept.viz module (PR #84)
• Support for the AlphaIMS implant (PR #87)
• New contribution guidelines (PR #92)
• New issue templates (PR #93)
• New code of conduct (PR #95)
• Host documentation on pulse2percept.readthedocs.io.

Bug fixes

• Fix nasal/temporal labeling for left eyes (commit 9c3bddc)
• Fix plot_fundus for left eyes (commit a6ffdbc)
• Fix scipy.special.factorial (commit c9631ae)

v0.4.3 (2018-05-21)

Highlights:

• Cython integration:
  • The model described in Nanduri et al. (2012) now uses a finite difference method implemented in Cython as opposed to FFT-based convolutions (PR #83)
  • Single-core benchmarks show a 200x speedup over a pure-Python implementation.

Bug fixes

• Python 2.7 unpacking error in plot_fundus (commit 3dd9d1e)

Deprecation removals

• pulse2percept.files.savemoviefiles
• pulse2percept.files.npy2movie
• pulse2percept.files.scale
• pulse2percept.stimuli.Movie2Pulsetrain
• pulse2percept.stimuli.retinalmovie2electrodtimeseries
• pulse2percept.utils.Parameters
• pulse2percept.utils.mov2npy

v0.3.0 (2018-02-20)

Highlights:

• New, faster axon map calculation
• Better plotting
• Support for left/right eye
