Change Log
==========

 - v0.1: Initial release
  - Basic prime calculation.
  - Uses a growing vector of known primes and gets the modulus of the number divided by these primes.
  - Uses type `long long' to hold prime numbers.
 - v0.2: Multi-Precision
  - Switch to C.
  - Uses GNU Multiple Precision library (GMP) to hold prime numbers, allowing for 'infinite' size.
  - Add `likely()' and `unlikely()' macros to optimize.
 - v0.2.1: Memory Leak Fixes
  - Fixed a major memory leak at the end of the program.
  - Added more optimizers.
 - v0.3: Optimizations
  - Algorithm skips half the known primes.
  - Removed `likely()' and `unlikely()' macros due to lack of information.
  - Improved performance.
 - v0.4: Fixed Algorithm
  - Fixed algorithm to actually calculate primes.
  - Added extra C99 optimizations.
 - v0.5: Minor Changes
  - Use `size_t' instead of `unsigned long long int'.
  - Minor optimizations to the algorithm.
  - Added commandline argument parsing.
 - v0.6: User Control
  - Allow user to choose base in which the prime numbers are printed.
  - Give option for primes to be saved to a file upon exit.
  - Free memory and leave instead of emergency exit.
 - v0.7: Data Saving
  - Allow user to save found primes to be loaded later.
  - User can save and read primes in raw output.
 - v1.0: Parallelization
  - Now completely parallelized.
  - Cleaned up/organized the code-base
  - Exporting files uses less memory
  - Allow searching for the nth prime number
  - Clearing some memory leaks
 - v2.0: Linked List
  - Code cleanup.
  - Replace OpenMP code with OpenMPI.
  - Use linked list for prime storage.
