Just over a week ago, a frustrated beta tester submitted logs from the Windows Live Messenger 9 beta, the logs exposed issues relating to bugs that won't be fixed, and features that were voted up by the group and subsequently rejected by the WLM team. Due to the nature of the logs and information sent to us, Neowin declined to make an issue of it, that didn't stop Ars Technica however, NDA or not, the WLM9 beta testing group is highly frustrated according to their posting below.
"The first Windows Live Messenger 9.0 Beta build was released in November 2007. The release brought the ability to sign into Messenger from up to four computers at once, the ability to choose customized sounds for your sign-in and for your contacts, URLs in Personal Status Messages, and Animated Display Pictures. However, features requested across the many Messenger programs such as Tabbed Conversations and the ability to decline a group conversation invite were nowhere to be seen."
