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 hebben versie 10.2.19 uitgebracht. De eerste stable uit de 10.2.x-tak stamt uit mei 2017 en heeft voor vijf jaar ondersteuning meegekregen. De beknopte aankondiging van deze uitgave ziet er als volgt uit:
