  • Syntax removals scheduled for this version have been pushed back to 2.33. We still recommend updating your Stan models as you are able. As a reminder, deprecated syntax which will be removed in minor versions can as a rule be updated automatically using find-and-replace tools or the Stan compiler's auto-formatting abilities. (#1303)
  • The deprecated --include_paths and --allow_undefined arguments have been removed, use --include-paths and --allow-undefined. (#1303)
  • Recursive user-defined functions no longer need forward declarations. (#1277)
  • Added overloads to eigenvalues and eigenvectors which accept a complex matrix as input. (#1282)
  • Fixed an issue where profile blocks could generate uncompilable C++ when used with --O1. (#1281)
  • Fixed an issue where the compiler would generate uncompilable C++ when a matrix expression featured mixed types of elements. (#1292)
  • Fixed an issue where a user-defined-function expecting real arguments could be passed an integer and exhibit integer behavior like truncating division. (#1296)
  • Fixed an issue where external functions could not be used in higher-order functions without the end-user supplying an implementation of our functor structs. (#1298)
  • Fixed a bug in transform_inits for models which used complex types (#1305)
  • Improved the error shown when an #included file cannot be found to list the paths it searched on. (#1273)
  • Improved --filename-in-msg for the command line version of stanc. Errors now use the requested name, not just warnings. (#1274)
  • Refactored how C++ is code-generated in the compiler. (#1233)
  • Added tests for various parts of the C++ backend which weren't previously tested, and added a --debug-lir flag to print out the C++ representation in a s-expression. (#1276)
  • Updated code generate of get_param_names (#1245)
  • Switched to std::endl instead of '\n' to end prints. (#1301)
  • Added a new function unconstrain_array to the generated code. This is currently not exposed. (#1305)
  • Added a --debug-generate-inits flag to stanc which behaves like --debug-generate-data but for declarations in the parameters block. (#1306)
  • Sped up some code which is critical to parsing. (#1302)
