Notating a symbol to be exported in code will only tell the linker where to find this symbol, so other object files can find it. However, this does not mean said symbol will also be exported to the host environment. Currently, we 'fix' this by force exporting every single symbol that is visible. This creates bigger binaries and means host environments have access to symbols that they perhaps shouldn't have. Now, users can tell Zig which symbols are to be exported, meaning all other symbols that are not specified will not be exported. Another change is we now support `-rdynamic` in the wasm linker as well, meaning all symbols will be put in the dynamic symbol table. This is the same behavior as with ELF. This means there's a 3rd strategy users will have to build their wasm binary.

The ultimate goal of the Zig project is to serve users. As a first-order effect, this means users of the compiler, helping programmers to write better software. Even more important, however, are the end-users.
Zig is intended to be used to help end-users accomplish their goals. Zig should be used to empower end-users, never to exploit them financially, or to limit their freedom to interact with hardware or software in any way.
However, such problems are best solved with social norms, not with software licenses. Any attempt to complicate the software license of Zig would risk compromising the value Zig provides.
Therefore, Zig is available under the MIT (Expat) License, and comes with a humble request: use it to make software better serve the needs of end-users.
This project redistributes code from other projects, some of which have other licenses besides MIT. Such licenses are generally similar to the MIT license for practical purposes. See the subdirectories and files inside lib/ for more details.
