MariaDB is ontstaan als fork van MySQL, nadat dit in 2009-2010 door Oracle werd overgenomen. Voor een overzicht van de verschillen tussen MariaDB en MySQL kun je op deze en deze pagina's terecht. MariaDB is een krachtige opensourcedatabaseserver, die vooral populair is als website- en forumdatabase. De ontwikkelaars timmeren druk aan de weg en hebben versie 10.4.5 uitgebracht als releasecandidate voor de 10.4.x-tak. De beknopte aankondiging van deze uitgave ziet er als volgt uit:
MariaDB 10.4.5 Release Notes

MariaDB 10.4.5 is a Release Candidate (RC) release.
Thanks, and enjoy MariaDB!
