CHANGES

# changes since the last release

  -- C++ networks now hardcode the coefficients in a function to
     compute the rates instead of storing a metadata table that is
     read at runtime (#329)

# 1.7.0

  -- the Rate class now knows how to make its function string in
     python and C++ (#328)

     (#326)

  -- a Nucleus no knows its binding energy (#220)

  -- many improvements to C++ output (#246, #214, #185, #183)

  -- added a diff method to a Library (#194)

  -- fixed rate sorting so it is more deterministic (#216)

  -- added forward() and backward() methods to Library (#207)

  -- added a default ReacLibLibrary function (#206)

     important missing rates (#188, #172)

# 1.6.0

  -- added support for C++ StarKiller / AMReX Microphysics networks
     (#152, #151, #149)

  -- centralized sympy code generation and removed common
     subexpression support from network generation (#145)

# 1.5.0

  -- Added gridplot function for plotting nuclides on a grid and
     coloring the cells by X, Y, Xdot, Ydot or activity

  -- Created a notebook and a script for generating rp-process
     networks. The script allows an arbitrary endpoint to be
     specified.

  -- Added a filter_function option to RateFilter and to the plotting
     functions that allows for filtering rates or nuclei using a
     user-defined Boolean map.

  -- Fixed a write_network crash if the RateCollection contains
     multiple rates with the same name.

  -- Deleted unused BLAS and VODE files previously used for the
     standalone Fortran outputs. These have been deprecated in favor
     of the StarKiller Microphysics network output as of v1.3.0.

  -- fixed screening for the 3-alpha rate

# 1.4.1

  -- Improvements for locating rate files in directories also
     containing python scripts or Jupyter notebooks

  -- Fixed a warning when using Numba

  -- Updated the requirements

# 1.4.0

  -- Added general support for tabulated weak rates from Suzuki, et
     al. 2016

  -- Added a simple pp network example
