# 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)

### 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)
