# Tint changes during Origin Trial
|
|
|
|
## Changes for M97
|
|
|
|
### Breaking Changes
|
|
|
|
* Deprecated `modf()` and `frexp()` builtin overloads that take a pointer second parameter have been removed.
|
|
* Deprecated texture builtin functions that accepted a `read` access controlled storage texture have been removed.
|
|
* Storage textures must now only use the `write` access control.
|
|
|
|
### New Features
|
|
|
|
* `any()` and `all()` now support a `bool` parameter. These simply return the passed argument. [tint:1253](https://crbug.com/tint/1253)
|
|
* Call statements may now include functions that return a value (`ignore()` is no longer needed).
|
|
* The `interpolate(flat)` attribute can now be specified on integral user-defined IO. It will eventually become an error to define integral user-defined IO without this attribute.
|
|
|
|
### Fixes
|
|
|
|
* Swizzling of `vec3` types in `storage` and `uniform` buffers has been fixed for Metal 1.x. [tint:1249](https://crbug.com/tint/1249)

|
## Changes for M95
|
|
|
|
### New Features
|
|
|
|
* The size of an array can now be defined using a non-overridable module-scope constant
|
|
* The `num_workgroups` builtin is now supported.
|
|
|
|
### Fixes
|
|
|
|
* Hex floats: now correctly errors when the magnitude is non-zero, and the exponent would cause overflow. [tint:1150](https://crbug.com/tint/1150), [tint:1166](https://crbug.com/tint/1166)
|
|
* Identifiers beginning with an underscore are now correctly rejected. [tint:1179](https://crbug.com/tint/1179)
|
|
* `abs()` fixed for unsigned integers on SPIR-V backend [tint:1179](https://crbug.com/tint/1194)
