There are two general issues fixed by this point release:
Deskbar can freeze at boot-up on read-only media.
Issue: Potential kernel level deadlocking issue in the network stack.
Solution: The cause of the deadlock was found and corrected.
Change: hrevr1alpha4-44701
Users can see a kernel crash at boot-up on read-only media.
Issue: Normalization never occurring on module image paths due to a bug in the hash table.
Solution: Hash table code was fixed preventing duplicate module images from loading.
Change: hrevr1alpha4-44700
We have replaced the R1A4 files on the website with R1A4.1 files to ensure these issues are thoroughly corrected. The archives are named "haiku-r1alpha4.1-*" and the image files contained within retain the "haiku-r1alpha4*" nomenclature.
If you have already installed R1A4, we recommend updating to R1A4.1. Thank you all for testing and supporting Haiku!
