+Interface Changes:
+- Overhauled the API for traced `cpptrace::exception` objects
+- Added `cpptrace::isatty` utility
+- Added specialized `std::terminate` handler and `cpptrace::register_terminate_handler` utility
+- Added `cpptrace::frame_ptr` as an alias for the appropriate type capable of representing an instruction pointer
+- Added signal-safe tracing support and a guide for [how to trace safely](signal-safe-tracing.md)
+- Added `cpptrace::nullable<T>` utility for better indicating when line / column information is not present
+- Added `CPPTRACE_FORCE_NO_INLINE` utility macro to cpptrace.hpp
+- Added `CPPTRACE_WRAP` and `CPPTRACE_WRAP_BLOCK` utilities to catch non-`cpptrace::exception`s and rethrow wrapped in a
+  traced exception.
+- Updated `cpptrace::stacktrace::to_string` to take a `bool color` parameter
+- Eliminated uses of `std::uint_least32_t` in favor of other types
+- Updated `object_frame` data member names
+
+Other changes:

+- Added libunwind as a back-end
+- Unbundled libdwarf
+- Increased hard max frame count, used by some back-end requiring fixed buffers, from 100 to 200
+- Improved libgcc unwind backend
+- Improved trace output when information is missing
+- Added a lookup table for faster dwarf line information lookup
