* `zig build --export [obj|lib|exe]` changed to `zig build_obj`, `zig build_lib` and `zig build_exe` respectively. * `--name` parameter is optional when it can be inferred from the root source filename. closes #207 * `zig build` now looks for `build.zig` which interacts with `std.build.Builder` to describe the targets, and then the zig build system prints TODO: build these targets. See #204 * add `@bitcast` which is mainly used for pointer reinterpret casting and make explicit casting not do pointer reinterpretation. Closes #290 * fix debug info for byval parameters * sort command line help options * `std.debug.panic` supports format string printing * add `std.mem.IncrementingAllocator` * fix const ptr to a variable with data changing at runtime. closes #289
