The algorithms no longer catch std::exception unconditionally. The Math library uses std::domain_error for recoverable errors, and these are the ones which are caught. (#3259)
Allow laplace sampling without evaluating log_prob for each draw. (#3261)
Allow laplace sampling to save the Hessian as a diagnostic output. (#3261)
Stan's RNG usages now uses a type definition stan::rng_t rather than hard coding a specific Boost RNG. (#3263)
Switched the pRNG used by default in the services and tests to be boost::mixmax. Note that this means seeds from previous versions will lead to different numerical results in this version. (#3264)
Add a new ranked R-hat diagnostic from Vehtari. (#3266)
Fixed an issue where Pathfinder would sometimes return more draws than requested. (#3279)

v2.34.0 (16 January 2024)

Resolved an issue in Pathfinder's multithreading which lead to non-reproducible results (#3239)
Improved the human-readability of the output of the JSON writer class (#3227)
Resolved various compiler warnings (#3228, #3234)
Added hooks to adaptive sampler methods to write adapted metric to JSON file. (#3230, #3248)
Changed bfgs and lbfgs's error messaging behavior so that the message is not split between stderr and stdout but is entirely sent to stderr. (#3238)
Fixed a bug in the stan opencl assign tests (#3219)
Updated PSIS to not add back the max and return the unnormalized resample ratios for stability (#3243)
Fixed an issue where trying to compute the potential scale reduction factor on an empty set of draws would lead to a crash (#3246)
Added flags to the Pathfinder service functions for turning off resampling and the calculation of the lp for the approximate draws. (#3249)
