 Bugfixes:
+ * Code Generator: Fix not entirely deterministic order of functions in unoptimized Yul output. The choice of C++ compiler in some cases would result in different (but equivalent) bytecode (especially from native binaries vs emscripten binaries)
  * Commandline Interface: Fix internal error when using ``--stop-after parsing`` and requesting some of the outputs that require full analysis or compilation.
  * Commandline Interface: It is no longer possible to specify both ``--optimize-yul`` and ``--no-optimize-yul`` at the same time.
  * SMTChecker: Fix encoding of side-effects inside ``if`` and ``ternary conditional``statements in the BMC engine.
