"LibreSSL has been forked off OpenSSL in 2014 to address a number of problems with the original package. However, since then OpenSSL development gained speed and the original reasons for the fork no longer apply. Furthermore, LibreSSL started to repeatedly fall behind and cause growing compatibility problems. While initially these problems were related to packages using old/insecure OpenSSL APIs, today they are mostly related to LibreSSL missing newer OpenSSL APIs (yet declaring false compatibility with newer OpenSSL versions). With the little testing it gets, our developers and users had to put a significant effort into fixing upstream packages. In some cases (e.g. Qt), upstream has explicitly refused to support LibreSSL, forcing us to maintain the patches forever. This in turn means that security fixes, regular version bumps or end-user system upgrades are often delayed because of necessary LibreSSL patching. What is even worse, major runtime issues managed to sneak in that broke production systems running LibreSSL in the past."
