Release Notes
0.5.0
- Moved repository to JuliaGNI
- Moved CI from Travis to GitHub
Breaking Changes
- Functions for initial guesses are now called v̄ and f̄ and can be prescribed separately from v and f in PDAE, HDAE, etc.
- Rename SPARK tableau constructors and unify distinct constructors for Lobatto tableaus with different number of stages
New Features
- Implement SPARK integrator for index-two DAEs
- Implement infrastructure for storing internal variables and solver output to atomic solutions
- Store internal variables of SPARK and VPRK integrators in atomic solution
- Add various five-stage Lobatto tableaus
- Add and clean up SPARK tableaus and add docstrings
- Add functions for checking symplecticity conditions of SPARK tableaus
- Add Aqua.jl tests
Fixes
- Fix initial guess warnings in tests by prescribing proper functions for v̄ and f̄ in example problems
- Fix update_multiplier() method for SPARK integrators
0.4.1
New Features
- Atomic solutions can now store a NamedTuple of internal variables of the integrator, including nonlinear solver output
- Output of internal variables has been added to VPRK integrators
- Add Gauss-Legendre tableaus for implicit partitioned Runge-Kutta methods
Fixes
- Revision of integrator type hierarchy
0.4.0
