==History== In October 2009, CakePHP project manager Garrett Woodworth and developer Nate Abele resigned from the project to focus on lithium,<ref>{{ cite web | last=Rampersad | first=Ryan | url=http://ryan.ifupdown.com/2009/10/23/the-state-of-cakephp/ | title=The State of CakePHP | date=2009-10-23 | access-date=2009-11-06 | url-status=dead | archive-url=https://web.archive.org/web/20091028221917/http://ryan.ifupdown.com/2009/10/23/the-state-of-cakephp/ | archive-date=2009-10-28 }}</ref><ref>{{cite web | url=http://li3.rad-dev.org/ | title=Lithium project web site | access-date=2009-11-06 | archive-url=https://web.archive.org/web/20180813075926/http://li3.rad-dev.org/ | archive-date=2018-08-13 | url-status=dead }}</ref> a framework code base originally being developed at the CakePHP project as "Cake3".<ref>{{cite web | url=http://bakery.cakephp.org/articles/view/the-cake-is-still-rising | title=The Cake is Still Rising | access-date=2009-10-25 | archive-url=https://web.archive.org/web/20091026150142/http://bakery.cakephp.org/articles/view/the-cake-is-still-rising | archive-date=2009-10-26 | url-status=dead }}</ref>

In 2012 the project gained official sponsorship from Engine Yard.<ref>{{cite web|url=http://www.h-online.com/open/news/item/Engine-Yard-sponsors-PHP-framework-Lithium-1618465.html|title=Engine Yard sponsors PHP framework Lithium|publisher=The H|date=15 June 2012}}</ref>

In January 2014 the project was rebranded under the name li₃.

With the release of version 1.0 on June 6, 2016, David Persson followed Nate Abele as lead developer of the project.<ref>{{cite web|title=Releasing 1.0|url=http://news.li3.me/post/145260633533/releasing-1-0}}</ref><ref>{{cite web|last1=Menge-Sonnentag|first1=Rainald|title=Das als Lithium gestartete PHP-Framework li3 erreicht Version 1.0|url=https://www.heise.de/developer/meldung/Das-als-Lithium-gestartete-PHP-Framework-li3-erreicht-Version-1-0-3225246.html|website=Heise Developer|date=2 June 2016 |access-date=23 April 2017}}</ref>

In May 2020 a framework also named lithium<ref>{{cite web|title=The Lithium C++ Libraries|website=GitHub |url=https://github.com/matt-42/lithium}}</ref><ref>{{cite web|title=TechEmpower Benchmarking for lithium|website=GitHub |url=https://github.com/TechEmpower/FrameworkBenchmarks/tree/master/frameworks/C%2B%2B/lithium}}</ref> scored the 4th place (out of 104) in the composite score of TechEmpower Web Frameworks Benchmarks Round 19,<ref>{{Cite web|title=TechEmpower Web Framework Performance Comparison|url=https://www.techempower.com/benchmarks/#section=data-r19&hw=ph&test=composite|access-date=2020-06-01|website=www.techempower.com}}</ref> but it is a modern C++17 asynchronous web server based on epoll, a totally different web framework from '''li₃'''.
