-The OpenSSL project depends on volunteer efforts and financial support from
-the end user community. That support comes in the form of donations and paid
-sponsorships, software support contracts, paid consulting services
-and commissioned software development.
-
-Since all these activities support the continued development and improvement
-of OpenSSL we consider all these clients and customers as sponsors of the
-OpenSSL project.
-
-We would like to identify and thank the following such sponsors for their past
-or current significant support of the OpenSSL project:
-
-Major support:
-
-	Qualys		http://www.qualys.com/
-
-Very significant support:
-
-	OpenGear:	http://www.opengear.com/
-
-Significant support:
-
-	PSW Group:	http://www.psw.net/
-	Acano Ltd.	http://acano.com/
-
-Please note that we ask permission to identify sponsors and that some sponsors
-we consider eligible for inclusion here have requested to remain anonymous.
-
-Additional sponsorship or financial support is always welcome: for more
-information please contact the OpenSSL Software Foundation.
+Please https://www.openssl.org/community/thanks.html for the current
