 * New Feature: Added presentation of imported types and TypeRef hashes for .NET binaries ([#363](https://github.com/avast-tl/retdec/issues/363), [#364](https://github.com/avast-tl/retdec/issues/364), [#428](https://github.com/avast-tl/retdec/issues/428)).
 * New Feature: Added computation and presentation of icon hashes for exact and also similarity matching in PE files ([#339](https://github.com/avast-tl/retdec/issues/339)).
+* Enhancement: Make `--generate-log` option of `retdec-decompiler.py` work on macOS ([#383](https://github.com/avast-tl/retdec/issues/383), [#450](https://github.com/avast-tl/retdec/pull/450)).
+* Enhancement: Replace recursion with iterative implementation in x87 FPU analysis in `retdec-bin2llvmir` ([#450](https://github.com/avast-tl/retdec/pull/450)).
 * Enhancement: The `new` LLVM IR to BIR converter is now the default (and only) back-end's converter. In most cases, this improves code structure and significantly speeds up decompilations ([#211](https://github.com/avast-tl/retdec/issues/211), [#508](https://github.com/avast-tl/retdec/issues/508), [#509](https://github.com/avast-tl/retdec/pull/509)).
 * Enhancement: The `fileformat` library, and all its object file modules, accept both `std::istream` and `(data, size)` pair, in addition to the original input file path.
 * Enhancement: Reduced the needed stack space in `retdec-llvmir2hll` ([#492](https://github.com/avast-tl/retdec/pull/492)).
