Bugs fixed in version 6.4
-------------------------
* Several issues with the `perfect_foresight_with_expectation_errors` command:
+ when used with no `endval`/`endval(learnt_in=1)` block but an
`endval(learnt_in=`t`)` block with t>1, converge could fail if homotopy was
needed (bug fixed in 9e8427e7b5c68e980edbb7fd9be945c66437a433)
+ combined with `homotopy_marginal_linearization_fallback`, it would return
incorrect results (bug fixed in a3f2a3893ad2309ba790d0897de4c56c89912f5e)
+ it would crash with `homotopy_marginal_linearization_fallback` option if
there were several distinct `shocks` or `endval` blocks with the
`learnt_in` option (bug fixed in 85bea5a68bcee16fe3c707c62e34bef56608e056)
* Using the `model_diagnostics` command with the `bytecode` option of the
`model` block or the `model_options` command would crash if the static
Jacobian was singular (bug fixed in e58c12555798c3cdb1b1bf991502b08b32dcd299)
* The `discretionary_policy` command with the `noprint` option would crash when
encountering a problem instead of continuing (bug fixed in
51e2ff303108427459836b8881cc9a43afeaad74)
* Using the `ramsey_model` command with models declared as `linear` would crash
during preprocessing when there is a lead/lag greater than 1 on endogenous
variables or any lead/lag on exogenous variables (bug fixed in
