The old algorithm (LBJ) is now available under stack_stock_algo = 6

They emit a warning under Octave

Deprecates simk.m which can now be removed

It is better to use bison-mode and flex-mode (see the wiki)

that it is possible to derive the solution function by a simple
inversion, but this doesn't check that all eigenvalues are larger than
one. It is better to use the standard algorithm with QZ decomposition

This can improve a bit optimization routines when parameter go beyond prior bounds during line search algorithms or when numerical gradient is computed.

Fixed optimizer = 5 for dsge-vars and all other cases that do not allow computing the outer product of gradient (non-linear optimizers as well).

Fixes around latex output: use of longtable for parameter estimates and various fixes for posterior analysis, also for parallel execution.

singular. The treatment of this case still needs to be further improved.

initval and endval for deterministic models. Added test cases for
deterministic models.

integer power arguments   to insure that they are positive

variables and probably violates Jensen inequality in some cases.

of log and pow functions so as to insure non-negative arguments
