Switching the open source license in 2013 from the [https://opensource.org/licenses/Sleepycat Sleepycat license] to the AGPL had a major effect on open source software. Since BDB is a library, any application linking to it must be under an AGPL-compatible license. Many open source applications and all closed source applications would need to be relicensed to become AGPL-compatible, which was not acceptable to many developers and open source operating systems. By 2013 there were many alternatives to BDB, and [[Debian|Debian Linux]] was typical in their decision to completely phase out Berkeley DB, with a preference for the [[Lightning Memory-Mapped Database]] (LMDB).<ref>{{cite mailing list | url=https://lists.debian.org/debian-devel/2014/06/msg00338.html | title=New project goal: Get rid of Berkeley DB (post jessie) | mailing-list=debian-devel | date=June 19, 2014 | author=Ondřej Surý |publisher=[[Debian]]}}</ref>
