### Fixed

## Before 0.30.0

### 0.29.0
- -Breaking-: Removed Display impl for flags. The Debug impl now reports flags by name.
- Functions now have a doc comment that links to the Vulkan spec
- Entry has a new method called `try_enumerate_instance_version` which can be used in a 1.0 context.
- The generator now uses `BTreeMap` for better diffs.
### 0.28.0
- Switched to a new [changelog](https://keepachangelog.com/en/1.0.0/) format
- Fixed a build issue on ARM.
- -Breaking- Arrays are now passed by reference.
- Builders are now marked as `#[transparent]`.
- -Breaking-  Renamed `.next(..)` to `push_next`. `push_next` is only available on structs that are passed directly. Additionally `push_next` only accepts structs that can be inserted into the pointer chain. Read the readme for more information.
- New -experimental- extensions. Those do not follow the semver rules and can be removed at any time.
- Added `AmdGpaInterface` extension.

# 0.27.0/1

- Extensions are now namespaced. `ash::extensions::khr::Swapchain`
- Removed vendor tags from extension methods
- Added missing functions for VkEvent
- The examples were updated to use the new builder pattern
- A SPIR-V parsing function `ash::util::read_spv`
- Added `get_pipeline_cache_data`

### 0.26.0

- Fix loader on MacOS.

- Expose function pointers for easier interop with external libraries.

- Builder now uses bool instead of Bool32.
### 0.25.0

- Adds support for Vulkan 1.1

- Constants are not represented as an `enum` anymore. Constants and flags are both represented as associated constants.

```Rust
flags: vk::COMMAND_POOL_CREATE_RESET_COMMAND_BUFFER_BIT,
//to
flags: vk::CommandPoolCreateFlags::RESET_COMMAND_BUFFER_BIT,

```

- Pretty printing for flags

- Handles can be loaded from outside of ash. See `SomeHandle::from_raw`. This is useful if you need to interact with a C library.

- Removing versioning from ash. `V1_X` are now gone. Versioning had very little benefit in practice, `Entry`, `Instance` and `Device` are now version free. A custom loader can still be implemented. The various traits still remain `DeviceV1_0`.

- `vk.rs` is now generated from `vk.xml`

- Ash now includes all docs inside the `vk.xml`, and are visible in rustdoc.

- `Default` is now implemented for all structs

- There is now a builder pattern

- Handles are now `#[repr(transparent)]`

- Various bug fixes


### 0.18.0
- Fixes arm build => uses libc everywhere. Remove `AlignByteSlice`.

### 0.17.0

- Refactor Align to use vk::DeviceSize.

### 0.16.0

- `map_memory` now returns a void ptr

- `ash::util::Align` is a helper struct that
can write to aligned memory.
