Which Mathematica versions have changed WolframLibraryVersion?

Question

A LibraryLink library compiled with headers having a certain WolframLibraryVersion will not work with Mathematica versions that support only earlier WolframLibraryVersions.

For example, a library compiled with M12.0 (WolframLibraryVersion == 5) will work not only in 12.0 but also in 12.1–13.0 (WolframLibraryVersion == 6). However, it will not work in 11.3 (WolframLibraryVersion == 4).

Which Mathematica versions use which WolframLibraryVersion?

Answer 1

Run the following to find out the WolframLibraryVersion for your Mathematica, and please help complete the table below, if any entries are missing.

StringCases[
 Import[FileNameJoin[{$InstallationDirectory, "SystemFiles", "IncludeFiles", "C", "WolframLibrary.h"}], "String"],
 StartOfLine ~~ ___ ~~ "WolframLibraryVersion" ~~ 
   Whitespace .. ~~ (v : DigitCharacter ..) ~~ Whitespace ... ~~ 
   EndOfLine :> v
]

Mathematica	WolframLibraryVersion
13.1 – 14.1	7
12.1 – 13.0	6
12.0	5
11.2 – 11.3	4
10.0 – 11.1	3
9.0	2
8.0	1

Notes

• LibraryLink was not available before 8.0.

Answer 2

When you come to version 13.1:

Needs["CCompilerDriver`"]
dll = CCompilerDriver`CreateLibrary["
#include <WolframLibrary.h>

EXTERN_C DLLEXPORT mint get_WolframLibraryVersion() {
    return WolframLibraryVersion;
}
", "dllfile", "Language" -> "C++"];

dec=LibraryFunctionDeclaration[fun->"get_WolframLibraryVersion",dll,{}->"MachineInteger"];
WolframLibraryVersion = FunctionCompile[dec, Function[{}, fun[]]]

Then we can get the library version:

WolframLibraryVersion[]
