RapidMiner 4.0beta2 (YALE) Released on June 25th, 2007 |
|
New release: on Monday, June 25th, 2007, Rapid-I released a new version of the open-source data mining software RapidMiner 4.0beta2 (formerly: YALE).
Because of legal issues, Rapid-I decided to change the name of YALE. The name RapidMiner was chosen for its fit to the company name Rapid-I and to the naming scheme of the line of products planned by Rapid-I for the future. Only the name changes. Everything else stays the same. RapidMiner / YALE will remain open-source software under GNU GPL and available to end-users free of charge and is also available under a commercial OEM license.
