In keeping with NetBSD's policy of maintaining only the current (2.0) and
most recent (1.6) release branches, the release of NetBSD 2.0 marks the 
end-of-life for NetBSD 1.5.  This means that the netbsd-1-5 branch will no 
longer be actively maintained.

For example:

- There will be no more pullups to the branch (even for security issues)
- There will be no security advisories made for 1.5 
- The current 1.5 releases on ftp.netbsd.org will be moved into    
  /pub/NetBSD-archive
