// this should change if the capabilities are added to the library
// such that archives can be created which can't be read by previous

// 1 - initial version
// 2 - made address tracking optional
// 3 - numerous changes - can't guarantee compatibility with previous versions
// 4 - Boost 1.34
// added item_version to properly support versioning for collections
// 5 - Boost 1.36
// changed serialization of collections: adding version even for primitive
// types caused backwards compatibility breaking change in 1.35
// 6 - Boost 1.41 17 Nov 2009
// serializing collection sizes as std::size_t
// 7 Boost 1.42 2 Feb 2010
// error - changed binary version to 16 bits w/o changing library version #
// That is - binary archives are recorded with #6 even though they are
// different from the previous versions. This means that binary archives
// created with versions 1.42 and 1.43 will have to be fixed with a special
// program which fixes the library version # in the header
// Boost 1.43 6 May 2010
// no change
// 8 - Boost 1.44
// separated version_type into library_version_type and class_version_type
// changed version_type to be stored as 8 bits.
// 10- fixed base64 output/input.
// 11- not changes
// 12- improved serialization of collections
// 13- simplified visibility, removed Borland, removed pfto
// 14- improved visibility, refactor map/set
// 15- corrections to optional and collection loading
// 16- eliminated dependency on <codecvt> which is buggy in some libraries
// and now officially deprecated in the standard
// 17- Boost 1.68 August 2018
// 18- addressed undefined behavior in archive constructors.
// init() called from base wrote archive header before archive
// was fully constructed.
// 19- Boost 1.76 April 2021
// 20- Boost 1.84 April 2021
