Effectively we have 2 separate modes:
* With Boost, which pulls in Config and few other core libraries.
* Without any Boost (detected via __has_include see
https://github.com/boostorg/math/pull/612/files) which assumes a fully
compliant C++11 compiler.
It's hard to point to a single set of diffs  there was first of all a
fair bit of work from Matt Borland to remove all traces of C++03
support.Â After that it turns out that there wasn't actually all that
much left in terms of dependencies.
Some other key PR's:
* Addition of standalone tests:
https://github.com/boostorg/math/pull/606%c2 (note these actually
conflicted with root CMake  there are some later fixes for that somewhere).
* Main standalone completion: https://github.com/boostorg/math/pull/597
* Remove core dependencies: https://github.com/boostorg/math/pull/589
* Remove Integer dependencies: https://github.com/boostorg/math/pull/588
* Conditionally remove Config: https://github.com/boostorg/math/pull/583
* Predef removal: https://github.com/boostorg/math/pull/582
* Remove throw_exception dependency:
https://github.com/boostorg/math/pull/577
* Remove type_traits dependency: https://github.com/boostorg/math/pull/576
* Boost.Assert: https://github.com/boostorg/math/pull/570
* Boost.Range: https://github.com/boostorg/math/pull/569
* Lambda: https://github.com/boostorg/math/pull/568
* smart_ptr: https://github.com/boostorg/math/pull/567
* Boost.Array: https://github.com/boostorg/math/pull/565
* Atomic: https://github.com/boostorg/math/pull/563
* Algorithm: https://github.com/boostorg/math/pull/563
There are others if you care to look, in particular mpl removal took a
look of PR's on it's own!
Best, John.
