[1] Features

• Update to LLVM16.
• Support building Tuplex for newer LLVM versions, up to LLVM v17.
• Remove typed pointers in LLVM IR code generation, use explicit LLVM types instead.
• Enable Apple Silicon support for Python3.9+.
• Add script support for building arm64 wheels for Apple Silicon (scripts/build_macos_wheels.sh)
• Add Github actions to build and test wheels for Intel Mac, Ubuntu 22.04.
• Add fallback for platforms for generated CSV parser without SSE4.2 instructions.
• Add support for Python 3.11.
• Use Github actions to build wheels for Python 3.8, 3.9, 3.10, 3.11 under both manylinux and macos.

[2] Bug Fixes

• Explicitly shut down AWS SDK (when built with) to avoid race condition of AWS threads in destructors.
• Fix ResolveTask issue when parsing single column CSV file with heterogeneous data.
• Refactor decoding of exceptions in ResolveTask into function.
• Fix Protobuf issue when using -DBUILD_WITH_ORC where ORC libraries may have been build with different Protobuf version than Tuplex causing issues when delocating the wheel under macOS (Intel/ARM).
• Fix exception handling in individual tasks, which did not unlock partitions in case of error leading to crash.
• Fix toPythonString() conversion in Row.
• Fix serialization bug for lists, tuples together with options.

[3] Improvements

• Explicitly mark export symbols in runtime shared object.
• Change test script for exceptions to use pytest.parametrize.
• Add dwarf/elf lib for backward under macOS to print stacktrace.
• Change to batch processing for result-set conversion for any strategy and explicitly check signals to avoid fine grained locking of GIL.
• Lower parameters/test data size for exception (merge) testing for faster CI.
• Change to pick up compatible zstd version in cmake to avoid conflicts with pre-installed, older zstd library.
• Add cache step for macOS in Github action to speed up brew installs.
• Fix issue in setup.py when Python executable is not in /usr/local.
• Remove Ubuntu 18.04 support, update Azure CI runner to use Ubuntu 22.04.
• Deprecate Python 3.6. and 3.7 support.
• Use newer ANTLR4 version 13.1 and require Java 11 as dependency.
• Support setting Python version when creating Lambda runner in scripts/create_lambda_zip.sh.
• Update dependencies in tuplex/ci containers, build Python version specific containers.
• Refactor code generation logic for iterators.
• Update to recent pybind11 version 2.11.1 from 2.10.4.
