v2.36.0 (10 December 2024)

• Removed code following the last round of syntax deprecations that is currently scheduled. The final one (use of real values in conditionals) is now a type error and can no longer be automatically canonicalized. (#1420)
• Added the jacobian += statement, an analogue of target += but which can be conditionally disabled by Stan's algorithms when a unadjusted estimate is required. (#1435, #1437, #1471)
• Added stochastic_row_matrix and stochastic_column_matrix transforms for matrix types. (#1442)
• Added the sum_to_zero_vector transform for vector types. (#1443)
• Added distribution: beta_neg_binomial, with corresponding lpdf, cdf, lcdf, lccdf, and rng functions. (#1452, #1459, #1467)
• Added all-vector signatures to the newer versions of wiener_lpdf. (#1451)
• stanc.js can now accept models which contain #include statements. A fourth argument is available on the javascript stanc function which must be either undefined or a object mapping included file names to Stan source code as strings. (#1433)
• Enabled OpenCL support for the binomial_logit and binomial_logit_glm distributions. (#1368)
• Fixed an issue where certain overloads of distributions could lead to the ~ statement producing uncompilable C++. (#1466, #1474)
• Fixed an issue where operator/ was not generating the correct C++ for complex linear algebra types. (#1421)
• Fixed an issue where certain variable names would end up conflicting with system-specific macros in the generated C++. (#1429)
• Fixed an issue where void functions were not given the same checks as returning functions, leading to uncompilable C++ in some cases. (#1471)
• Updated parameter code generation to use auto so that the parameter types for matrices can be Eigen maps. (#1441)
• Rolled back js_of_ocaml to 5.4.0 for compatibility with QuickJS. (#1427)
• Added builds of stanc.js with pretty-printing and debug info. (#1440)
