# Brazil Public Test Release Notes

## What's New In This Release (most recent changes at top)

- 0.4.53

- Fixes shade rate errors with certain sampling combinations, notably when combining shade rate undersampling and image undersampling.
- Removed the 'autobackup may affect render times' warning.
- Added a new console message that auto-backup has been disabled and will be re-enabled at render end (if it was enabled).
- Created a new sampling subclass which is much lighter in memory overhead. 63% less memory used. This is used by the adaptive depth of field sampler and reduces the memory required for depth-of-field by 63%.
- Depth of field sampling now uses a special Shade loop in ShadeClient that is a bit more efficient. Depth of field should be slightly faster as a result of this and the reduced memory footprint.
- Fixes crashes (bug#237?) with rayFX ray tracing combined with GI, skylight, or arealighting.
- fixes bug#235 - Omni with raytraced shadows with csg do not render the shadows correctly in the Y axis (thanx Johan and Liimuri)

- 0.4.52a

- Quicky fix for the Stats button moving when resizing the console.
- Fixes the console crash (bug #284), which also fixes the missing map cancel not working with the console closed bug.
- fixes the prob with the missing UV map dialog not being able to cancel the render.
