@@ -345,3 +345,12 @@ What (Why):
When: January 2009 or Linux 2.7.0, whichever comes first
Why: Superseded by newer revisions or modules
Who: Jan Engelhardt <jengelh@computergmbh.de>
+
+---------------------------
+
+What: b43 support for firmware revision < 410
+When: July 2008
+Why: The support code for the old firmware hurts code readability/maintainability
+ and slightly hurts runtime performance. Bugfixes for the old firmware
+ are not provided by Broadcom anymore.
+Who: Michael Buesch <mb@bu3sch.de>
