+Small bugfix release.

+Release notes:

 Changes in v0.7.14
 
 This release wraps up our work for 4GB gpus mining ethash. Linux 4GB are verified to mine up to and including epoch 381 on drivers 18.50/19.30/19.50/20.10. After that, we have added support for extended mining from epoch 382 and up. Extended mining is a trade-off between hashrate and being able to mine at all, gpus will lose additional hashrate for every extra epoch. Please see the Linux section in the ETHASH_4GB_HOWTO.txt for more details and instructions.
