+Bugs fixed in version 4.5.6
+---------------------------
+
+* TaRB sampler: incorrect last posterior was returned if the last draw was rejected (bug fixed in [433a681](https://github.com/DynareTeam/dynare/commit/433a68169d3a1576992bdf523c3265d17679f23f)).
+* Fixed online particle filter by drawing initial conditions in the prior distribution (see [ef22c71](https://git.dynare.org/Dynare/particles/commit/ef22c716d3e23f749b82cb0e73392ddcf93c42b4))
+* Fixed evaluation of the likelihood in non linear / particle filters (see [427e88e](https://git.dynare.org/Dynare/particles/commit/427e88e6b41bd4d228d010536db30f40f2b00aee), [1f08164](https://git.dynare.org/Dynare/particles/commit/1f08164b05b6276f82cb48ca27ccde54e9f634c7) and [35c3a9f](https://git.dynare.org/Dynare/particles/commit/35c3a9fcd9181d1f5ba250172a6abf5daa0a04dd))
+* Added missing documented `montecarlo` option in Gaussian Filter and Nonlinear Kalman Filter (bug fixed in [ee6eaa8](https://git.dynare.org/Dynare/particles/commit/ee6eaa8449033b7074a468646e93dbaaf76160c9) and [28f7c76](https://git.dynare.org/Dynare/particles/commit/28f7c7621babacfa6eb7588b3ec25e47914dedb1))  
+* Added back a flag to deal with errors on Cholesky decomposition in the Conditional Particle Filter (bug fixed in [43615ce](https://git.dynare.org/Dynare/particles/commit/43615ce4f6bd522f3a7b309e3025204b9ab9df59))
+* Macroprocessor `length()` operator was returning 1 when applied to a string. Macroprocessor now raises an error when `length()` operator is called on an integer and return the number of characters when applied to a string (bug fixed in [d056df3](https://github.com/DynareTeam/dynare/commit/d056df3245a88c03b2c306496f48dafa7c17248e))
+* `mode_compute=8`: the error code during mode-finding was not correctly handled, resulting in crashes (bug fixed in [9722917](https://github.com/DynareTeam/dynare/commit/97229177b44cfabcafa8f4ab4eada0de7c9cc37c))
+* Identification was not correctly displaying a message for collinear parameters if there was no unidentified parameter present (bug fixed in [b8094a2](https://github.com/DynareTeam/dynare/commit/b8094a2e8494e4cb65eebd710c9ac47adee5aa7f) and [6607d39](https://github.com/DynareTeam/dynare/commit/6607d3907a0ddfcb8f13c70c6a9c6f9b533eb2db))
+
 Bugs fixed in version 4.5.5
 ---------------------------
-* Identification was crashing during prior sampling if `ar` was initially too low  (bug fixed in [09ac7f6](09ac7f6249e1553396ab0b70ff7e96ed72aafb1c)).

+* Identification was crashing during prior sampling if `ar` was initially too low  (bug fixed in [09ac7f6](09ac7f6249e1553396ab0b70ff7e96ed72aafb1c))
 * The `align` method on `dseries` did not return a functional second `dseries` output (bug fixed in [667bfb](https://github.com/DynareTeam/dynare/commit/667bfb69480b3b45afcc4449411e27707a0cd7b6)).
 * Predetermined variables were not properly set when used in model local variables (bug fixed in [229476](https://github.com/DynareTeam/dynare-preprocessor/commit/d686275da142e2d1e1afcdb32785c25f25b5a5a7))
 * `perfect_foresight_solver` with option `stack_solve_algo=7` was not working correctly when an exogenous variable has a lag greater than 1 (bug fixed in [8913791](https://github.com/DynareTeam/dynare/commit/8913791ff0972f8a56d6c5d0d325d1cb6fda7189) and [7948460](https://github.com/DynareTeam/dynare/commit/79484607a7038620372ee6b8a9be746a9c5c8448))
