1) algo_truncation: sets the number of iterations for a truncated guess-verify algorithm (i.e. if max_iter<=algo_truncation, no error is triggered on output, but the user is happy with the last regime in the algorithm)
2) reset_regime_in_new_period: is set to true, it resets the guess regimes to unconstrained when a new shock arrives, instead of starting with a guess regime consistent with the one identified in previous time periods. this sometimes allows more robust convergence/identification of the regimes
— Fix preprocessor crash when a [static] equation contains a “var_expectation” operator
– Occbin: handle external functions in “occbin_constraints”
— Occbin: add more sanity checks on expressions in “occbin_constraints” block
These command solve the problem where agents think they know perfectly the
future (they behave as in perfect foresight), but make expectation errors.
Hence they can potentially be surprised in every period, and their expectations
about the future (incl. the final steady state) may change.
Currently the sequence of information sets needs to be passed through a CSV
file. Another interface may be added in the future.
The algorithm uses a sequence of (true) perfect foresight simulations (not
necessarily as many as there are periods, because if the information set does
not change between two periods, there is no need to do a new computation).
There are two possibilities for guess values:
— the default is to use the initial steady state for the simulation using the
first-period information set; then use previously simulated values as guess
values
— alternatively, with the terminal_steady_state_as_guess_value option, use the
terminal steady state as guess value for all future periods (this is actually
what the “true” perfect foresight solver does by default)
In several places, there was only a general link to the old Dynare wiki. This
can be confusing, because we no longer use this wiki. Rather use specific links
to the pages that were not migrated to the new wiki.

The formulas are taken from commit 2a3ba743401693c5927acc936e27377f123f6d56 of
the homebrew-core repository.
The gcc.rb formula was modified by adding “cellar: :any” to all bottles (see
https://github.com/Homebrew/brew/blob/master/docs/Bottles.md).
The preprocessor has been updated accordingly (and the detection of the GCC
installed by Dynare package has also been fixed).
