* `analyzeContainer` now has an `outdated_decls` set as well as `deleted_decls`. Instead of queuing up outdated Decls for re-analysis right away, they are added to this new set. When processing the `deleted_decls` set, we remove deleted Decls from the `outdated_decls` set, to avoid deleted Decl pointers from being in the work_queue. Only after processing the deleted decls do we add analyze_decl work items to the queue. * Module.deletion_set is now an `AutoArrayHashMap` rather than `ArrayList`. `declareDeclDependency` will now remove a Decl from it as appropriate. When processing the `deletion_set` in `Compilation.performAllTheWork`, it now assumes all Decl in the set are to be deleted. * Fix crash when handling parse errors. Currently we unload the `ast.Tree` if any parse errors occur. Previously the code emitted a LazySrcLoc pointing to a token index, but then when we try to resolve the token index to a byte offset to create a compile error message, the ast.Tree` would be unloaded. Now we use `LazySrcLoc.byte_abs` instead of `token_abs` so the error message can be created even with the `ast.Tree` unloaded. Together, these changes solve a crash that happened with incremental compilation when Decls were added and removed in some combinations.

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.
