Editing SQL-Ledger (section)

== Licensing issues ==

At its inception, SQL-Ledger used the GNU GPL 2.0 license. In 2005, Debian legal questioned whether or not the program belonged in Free or Non-Free, due to wording in the ''Terms and Conditions'' notice in the tarball.<ref>{{cite web |url=http://lists.debian.org/debian-legal/2005/04/msg00044.html |title=sql-ledger may belong in non-free }}</ref>
In late 2006, [[LedgerSMB]] was created as a secure fork of SQL-Ledger.  In early 2007, SQL-Ledger 2.8 was released under the '''SQL-Ledger Open Source License'',<ref>{{cite web |url=http://yro.slashdot.org/article.pl?sid=07/04/15/1759254 |title=SQL-Ledger Relicensed, Community Gagged |website=Slashdot}}</ref> a license which retroactively revokes all previous licenses under which the covered code had been released.<ref>{{cite web |url=http://www.purple.dropbear.id.au/sql-ledger-license-changed-no-longer-gpl-when-gpl-software-goes-bad |title=When GPL software goes bad |website=Realm of the Purple Dropbear |archive-url=https://web.archive.org/web/20070618032337/http://www.purple.dropbear.id.au/sql-ledger-license-changed-no-longer-gpl-when-gpl-software-goes-bad/ |archive-date=2007-06-18 }}</ref> That version also contained an "anti-forking" clause.
However, within a month, SQL-Ledger 2.8.1 was released, under the GNU GPL 2.0.
