# Tint changes during Origin Trial
## Changes for M108
### New features
* `textureSampleBaseClampToEdge()` has been implemented. [tint:1671](crbug.com/tint/1671)
### Deprecated Features
* The `external_texture` overload of `textureSampleLevel()` has been deprecated. Use `textureSampleBaseClampToEdge()` instead. [tint:1671](crbug.com/tint/1671)
## Changes for M107
