Changelog

All changes important to the user will be documented in this file.

The format is based on Keep a Changelog and this project adheres to Semantic Versioning

3.0.0a1 - 2019-6-17

Added

  • Added numpy reader and writer.
  • Adds a helper script to clean the project directory of caches.
  • Adds initial documentation for PyPWA.
  • Added support for 3 Vectors, 4 Vectors, and Particles
  • Added ParticlePool to aid in working with multiple Particles
  • Added a binning utility that supports multiple binning variables and dimensions
  • Added PyTables support, so that large datasets can be easily managed

Changed

  • All program names have been lowercased
  • Configuration package has been compressed into a single module
  • PySimulate now is a library that has no UI, and has a UI portion that exclusively works with interfacing
  • Fuzzywuzzy is now optional
  • Process package is now a single module. Interface no longer uses IS_DUPLEX
  • Bulk of program functionality moved to libs, progs being just for UI
  • Builtin Plugins moved to libs, old plugin's plugins have still reside in plugins, but under a package with the appropriate name. I.E. data plugins are in plugins/data.
  • All file related libs have been moved to libs/file
  • Combined optimizers with fit library
  • GAMP was updated to use Particles and ParticlePool
  • Files with extra newline should parse correctly now
  • CSV and TSV files will be lf instead of crlf on linux systems now

Removed

  • Nestle Minimization. There is currently no clear way to have Minuit and Nestle to operate with each other nicely. Implementation for multiple optimizers will remain, as well as new associated issues created.
  • Removed support for all version of Python before 3.7

2.2.1 - 2017-10-16

Fixed

  • Setup would pull in unstable Yaml parser

2.2.0 - 2017-7-26

Added

  • Process Plugin support for List Data
  • Adds Exception handling to Processes
  • PyMask support for multiple masking files.
  • PyFit will now filter out events if the Bin value is 0
  • The user can AND, OR, or XOR masks together with PyMask

Changed

  • Removed previous_event from Process Interface
  • Duplex Pipes are used over Simplex Pipes for Duplex Processes
  • Changes get_file_length to using a binary buffered search.
  • Moved PyPWA.core.shared to PyPWA.libs
  • Split interface's plugins and internals to their own separate file based on the interfaces purpose.
  • PyFit no longer assumes bins are named 'BinN' you must specify Bin names in 'internal data'.
  • Multiplier effect for the Minimizers has been moved to the individual likelihoods.
  • PyMask defaults to AND operations instead of or now.

Fixed

  • PyFit will now shutdown correctly when killed with Ctrl-C or other interrupt.
  • The ChiSquared will no longer be multiplied by -1 when being minimized.
  • Data Parser's Cache would crash on very large files.

2.1.0 - 2017-6-30

Added

  • Argument Parser for simple programs where a configuration file would be unneeded overhead for the user.
  • Numpy Data support for single arrays and pass fail files.
  • Data Plugin now has two array types, Single Array and Columned Array
  • Memory and Iterator objects now imported into PyPWA
  • Iterators report length now
  • Masking utility 'PyMask' to mask and translate data

Changed

  • Plugin Loader now returns initialized objects
  • Renamed shell to progs
  • Moved all shell related items into a package called shell inside progs
  • Renamed CHANGELOG.mg to CHANGELOG.md
  • Renamed 'blank shell module' to 'blank program module'
  • Removed support for boolean and float arrays from EVIL Parser
  • Renamed internal GAMP type to Tree type
  • Split flat data into Columned data and standard arrays

Fixed
