Changes for version 0.70 - 2017-12-02

  • FIXES
    • prime_count(a,b) incorrect for a={3..7} and b < 66000000. First appeared in v0.65 (May 2017). Reported by Trizen. Fixed.
    • Also impacted were nth_ramanujan_prime and _lower/_upper for small input values.
  • FUNCTIONALITY AND PERFORMANCE
    • Some utility functions used prime counts. Unlink for more isolation.
    • prime_count_approx uses full precision for bigint or string input.
    • LogarithmicIntegral and ExponentialIntegral will try to use our GMP backend if possible.
    • Work around old Math::BigInt::FastCalc (as_int() doesn't work right).
    • prime_memfree also calls GMP's memfree function. This will clear the cached constants (e.g. Pi, Euler).
    • Calling srand or csrand will also result in the GMP backend CSPRNG functions being called. This gives more consistent behavior.
  • OTHER
    • Turned off threads testing unless release or extended testing is used. A few smokers seem to have threads lib that die before we event start.
    • Removed all Math::MPFR code and references. The latest GMP backend has everything we need.
    • The MPU_NO_XS and MPU_NO_GMP environment variables are documented.
