This is a minor new release, the API and ABI (Application binary interface) are backwards compatible.
The sieving algorithm has been improved by annotating branches with likely/unlikely and __builtin_unreachable(). This improves the performance of the S2_hard and D formulas by up to 5%. GCC benefits most from these changes (Clang's performance was already very good before).
Updates may require up to 24 hours to propagate to mirrors. If the following command doesn't work, please retry later:
