-## [Unreleased]
+## [0.5.0] - 2020-02-07
+
+### Added
+
+- This release contains the start of a preprocessor.
+It is in very early stages and will crash on any inputs other than
+`#if`, `#else`, `#ifdef`, and `#endif`. I recommend using your host preprocessor until this one is further along.
+
+- Added an error limit. Instead of overwhelming you with dozens of errors in a file with a misplaced `{`, rcc will now report at most 10 errors in one run. This can be configured with `--max-errors n`, see `rcc --help` for more details.
+
+- Added a recursion limit. Now, rcc will exit with an error instead of crashing on highly nested inputs (200+ parenthesis in a row).
+
+### Changed
+
+- Fold `char` expressions, such as `'1' - '0'`
+- Display characters properly in error messages (e.g. '1' instead of 49)
+- Various additional `CompileError`s have been added. This allows inspecting the type of an error dynamically instead of having to blindly display the string.
+- The `Compile` API now takes an `Opt` struct instead of 4 different parameters. This should make it easier to add more options in the future.
+- Use Graham's name in the 'authors' field instead of his username
+
+### Fixed
+
+This release fixed many bugs found by [honggzfuzz](https://github.com/rust-fuzz/honggfuzz-rs). Thank you to @Byter09 for helping me get it set up as well as lending me CPU time for the fuzz runs!
+
+- Fix crash on nested functions (`int f() { int g() {} }`)
+- Fix crash on assignments other than identifiers and pointers (e.g. `++A[1]`)
+- Fix _many_ crashes in constant folding. A giant thank you to @pythondude325 for redesigning and implementing the new interpreter!
+- Fix crash on `return` in a `do-while` loop
+- Fix crash on `int f(void, void)`, and `int f(void, i)`
+- Fix crash on using typedefs in an expression context (`typedef int i; int j = i;`)
+- Fix crash on label in switch without braces
+- Fix crash on `!void`
+- Fix crash on `(int)void`
+- Fix crash on invalid syntax in an `if` statement (`if (1) {} else else`)
+- Fix crash on `!(_Bool)1)`
+- Fix crash on using invalid structs in an expression
+- Fix crash on signed overflow when incrementing the counter used for `enum` constants (e.g. `enum { A = -1u, B }`)
+- Fix crash on invalid break after switch
+- Fix crash on aggregate initializers with misleading braces (`int a[][3] = {1,2,3};`). `rcc` now properly initializes this as `int a[1][3] = {{1,2,3}};`.
+- Fix crash on unterminated string at the end of a file
+
+And the non-crash fixes:
+
+- Don't allow taking the address of `register` variables
+- Don't allow assigning to `const` variables
+- Remove backslashes before newlines
