   8 <P>This document describes the new features in CUPS 1.2. If you
   9 have never used CUPS before, read the <A
  10 HREF="overview.html">"Overview of CUPS"</A> document instead.
  11 CUPS 1.2 adds many new features to CUPS 1.1.x:</P>

  39 1. Networking
  40    a. IPv6
  41         i. Next-generation Internet support
  42        ii. ????
  43    b. Domain sockets
  44         i. Enhanced performance under load for local clients.
  45        ii. Authentication without passwords on platforms that support it.
  46 -->
  47
  48 <P>CUPS 1.2 adds support for IPv6 and domain sockets. The IPv6
  49 support allows CUPS to work with the next-generation Internet as
  50 well as taking advantage of automatic local network
  51 configuration. Domain sockets provide 5 to 10 times faster
  52 printing from the desktop.</P>

  58 2. Printer Browsing
  59    a. CUPS browsing updates
  60         i. "Delete" bit for printers
  61        ii. "lease-time" for printers so that clients and servers don't need
  62           the same browse timeout/interval settings
  63       iii. Additional attributes/default options for network-wide defaults
  64        iv. Network default printer
  65         v. Ability to control send and receive protocols independently
  66    b. Rendevous support
  67    c. LDAP support
  68    d. Per-printer sharing
  69 -->
  70
  71 <P>CUPS 1.2 adds support for Bonjour/mDNS and LDAP-based printer
  72 sharing. Printers can be shared or "published" individually,
  73 allowing a server to only share specific printers, and you can
  74 set which protocols to use for local and remote printers.
  75 Previously CUPS would share all or none of its printers and use
  76 the same protocols for local and remote printers.</P>
  77
  78 <H3>CUPS Browse Protocol</H3>
  79
  80 <P>The CUPS browse protocol has also been upgraded. New type
  81 bits, authenticated, default, and deleted, provide key
  82 information to clients. The "authenticated" type bit tells
  83 clients that the print queue requires authentication when
  84 printing. The "default" type bit tells clients that the print
  85 queue should be used as the default unless the user sets a
  86 different one. The "deleted" type bit is set when a printer is
  87 deleted from the server - this allows the client to remove its
  88 copy of a printer immediately rather than waiting for it to
  89 timeout.</P>
  90
  91 <P>Previously, a change to the BrowseTimeout setting on the
  92 server had to be mirrored to each client. Browse packets now
  93 include printer lease time information which allows the server to
  94 use a different timeout setting than its clients, making
  95 configuration simpler and more reliable.</P>
  96
  97 <P>Browse packets can also now contain connection options to be
  98 used when printing to the server. This allows the administrator
  99 to require encryption or compress print jobs for certain
 100 printers. This is most often used when printing over
 101 limited-bandwidth WAN connections.</P>
