+// this should change if the capabilities are added to the library

+// versions of this library
+// 1 - initial version
+// 2 - made address tracking optional
+// 3 - numerous changes - can't guarentee 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
