# 1.0.0\r
- **[breaking change]** Macro now generates [associated constants](https://doc.rust-lang.org/reference/items.html#associated-constants) ([#24])\r
\r
- **[breaking change]** Minimum supported version is Rust **1.20**, due to usage of associated constants\r
\r
- After being broken in 0.9, the `#[deprecated]` attribute is now supported again ([#112])\r
\r
- Other improvements to unit tests and documentation ([#106] and [#115])\r
\r
[#24]: https://github.com/rust-lang-nursery/bitflags/pull/24\r
[#106]: https://github.com/rust-lang-nursery/bitflags/pull/106\r
[#112]: https://github.com/rust-lang-nursery/bitflags/pull/112\r
[#115]: https://github.com/rust-lang-nursery/bitflags/pull/115\r
\r
## How to update your code to use associated constants\r
Assuming the following structure definition:\r
```rust\r
bitflags! {\r
  struct Something: u8 {\r
     const FOO = 0b01,\r
     const BAR = 0b10\r
  }\r
}\r
```\r
In 0.9 and older you could do:\r
```rust\r
let x = FOO.bits | BAR.bits;\r
```\r
Now you must use:\r
```rust\r
let x = Something::FOO.bits | Something::BAR.bits;\r
```\r
\r
# 0.9.1\r
- Fix the implementation of `Formatting` traits when other formatting traits were present in scope ([#105])\r
\r
[#105]: https://github.com/rust-lang-nursery/bitflags/pull/105\r
\r
# 0.9.0\r
- **[breaking change]** Use struct keyword instead of flags to define bitflag types ([#84])\r
\r
- **[breaking change]** Terminate const items with semicolons instead of commas ([#87])\r
\r
- Implement the `Hex`, `Octal`, and `Binary` formatting traits ([#86])\r
\r
- Printing an empty flag value with the `Debug` trait now prints "(empty)" instead of nothing ([#85])\r
\r
- The `bitflags!` macro can now be used inside of a fn body, to define a type local to that function ([#74])\r

  This may break code that defines its own set method\r
