| 53 | // 1 - initial version |

| 55 | // 3 - numerous changes - can't guarentee compatibility with previous versions |
| 56 | // 4 - Boost 1.34 |
| 57 | // added item_version to properly support versioning for collections |
| 58 | // 5 - Boost 1.36 |
| 59 | // changed serialization of collections: adding version even for primitive |
| 60 | // types caused backwards compatibility breaking change in 1.35 |
| 61 | // 6 - Boost 1.41 17 Nov 2009 |
| 62 | // serializing collection sizes as std::size_t |

| 64 | // error - changed binary version to 16 bits w/o changing library version # |
| 65 | // That is - binary archives are recorded with #6 even though they are |
| 66 | // different from the previous versions. This means that binary archives |
| 67 | // created with versions 1.42 and 1.43 will have to be fixed with a special |
| 68 | // program which fixes the library version # in the header |
| 69 | // Boost 1.43 6 May 2010 |
| 70 | // no change |
| 71 | // 8 - Boost 1.44 |
| 72 | // separated version_type into library_version_type and class_version_type |
| 73 | // changed version_type to be stored as 8 bits. |
| 74 | // 10- fixed base64 output/input. |
| 75 | // 11- not changes |
| 76 | // 12- improved serialization of collections |
| 77 | // 13- simplified visibility, removed Borland, removed pfto |
| 78 | // 14- improved visibility, refactor map/set |
| 79 | // 15- corrections to optional and collection loading |
| 80 | // 16- eliminated dependency on <codecvt> which is buggy in some libraries |
| 81 | // and now officially deprecated in the standard |
