greta.dynamics 0.2.3

CRAN release: 2026-07-22

This release restores greta.dynamics to CRAN. It was archived in September 2025 as a consequence of its dependency, greta, being archived. greta 0.6.0 returned to CRAN in July 2026, which unblocks this resubmission.

Documentation fixes

• The @return documentation for iterate_matrix(), iterate_dynamic_matrix() and iterate_dynamic_function() named a list element stable_state, which none of these functions actually return. The documentation now uses the real names: stable_distribution for iterate_matrix(), and stable_population for iterate_dynamic_matrix() and iterate_dynamic_function().
• Added worked examples to iterate_dynamic_matrix() and iterate_dynamic_function(), which previously had none.

Internal changes

• Now requires greta >= 0.6.0.
• Removed LazyData from DESCRIPTION, as the package ships no data.

greta.dynamics 0.2.2

CRAN release: 2024-11-14

New features

• Added iterate_dynamic_function() and iterate_dynamic_matrix()

Breaking Changes

• Updated internal ODE interface to match new tensorflow probability API. This involves now only supporting two solvers, “dp”, and “bdf”. The Default is “dp”, which is similar to deSolve’s “ode45”. The “dp” solver is Dormand-Prince explicit solver for non-stiff ODEs. The “bdf” solver is Backward Differentiation Formula (BDF) solver for stiff ODEs. Currently no arguments for “bdf” or “dp” are able to be specified.

Internal changes

• import rlang, cli, use latest version of greta, 0.5.0
• use internal checking functions
• use snapshot testing for checking error messages

greta.dynamics 0.2.1

• Use sentinel “_PACKAGE”

greta.dynamics 0.2.0

CRAN release: 2022-09-05

• Added a NEWS.md file to track changes to the package.
