AMICI v0.11.20

New:

• Changed parameter mappings such that unassigned values have non-nan default values. This fixes erroneous evaluation of llh as NaN in some situations (#1574)
• Added support for Python 3.10 (#1555)

Fixes:

• Fixed a bug when simulation start time was not transferred when copying a solver instance (#1573)
• Fixed a bug which led to incorrect sensitivies for models with multiple assignment rules or rate rules (#1584)

Other:

• Update CI and documentation settings (#1569, #1527, #1572, #1575, #1579, #1580, #1589, #1581)
• Extend set of validated benchmark models that is checked during CI (#1571, #1577)
• Fixed string formatting in derivative checks (#1585)
• Added helper methods to save and restore model instance-only settings (#1576)

AMICI v0.11.19

New:

• Added support for observable transformations (lin/log/log10) (#1567). Thereby supporting additional noise distributions in combination with least squares solvers.

Fixes:

• Fixed a bug when Newton sensitivity computation was activated despite specifying newton_steps == 0. The error occurs when simulation converges to a steadystate but simulation sensitivities are not converged according to convergence criteria. In that case simulation returned failure, but the newton rootfinding "finds" a steadystate even before the iteration check, leading to the erroneous computation of sensitivities via Newton/IFT. For singular jacobians this means the overall simulation still fails, but a different, more informative error message is displayed. (#1541)
• Fixed a bug where argument outdir in ODEExporter.__init__ would not be used (#1543)

Other:

• Improve checking support for SBML extensions (#1546)
• SBML import: Use more descriptive IDs for flux expressions (#1551)

• Removed distutils dependency (#1557)
• Require sympy<1.9
