# [2021.01.27] Releases on GitHub Today I tried to auto-check some code with CircleCI. The code worked perfectly on my laptop, of course, but depended on using Mace4 which was absent in a CircleCI container. The only way to get a Mace4 binary is to compile it from the source. But compiling some piece of software during continuous integration procedure of another seemed to be a bad idea. So I decided to compile Mace4 in advance and to 'release' it for my fork of this marvellous tool. I mean, that's amazing that although its author, Dr McCune, is dead for several years already, some people use the programme! Looks like cyber-immortality in action:)
