1) Alice 2.4 is absent from the Downloads menu on the main page, instead being replaced with Alice 2.3, which is a prior version. The Alice 2.4 download links still exist at
http://www.alice.org/index.php?page=...nload_alice2.4.
2) The Alice 2.3 release notes page is missing, giving this error:
PBworks Error
Unable to determine workspace name. This might be indicative of a server misconfiguration.
