 * Linux 2.6.24 (~-!ToDo: write summary of those [wiki:Self:KernelFAQ#new-features-in-lenny new-features-in-lenny]-~); no support for Linux 2.4  * Linux 2.6.25 (~-!ToDo: write summary of those [wiki:Self:KernelFAQ#new-features-in-lenny new-features-in-lenny]-~); no support for Linux 2.4

New stuff in lenny:

Kernel and utilities

Expected

  • Linux 2.6.26

Desktop

  • Compare packages pulled by tasks, especially desktop and laptop [TODO]
  • GNOME 2.22 [http://library.gnome.org/misc/release-notes/2.22/]-~

    • many applications now use the new gio library instead of gnome-vfs, leading to important performance improvements
    • A handful of packages (namely nautilus, gnome-panel and libgnome) will be shipped in their 2.20 version, as we felt gvfs was not stable and featured enough for a stable Debian release. We include our patched, rock-solid version of gnome-vfs instead, even though it means less performance.
    • Experimental webkit support (epiphany-webkit)

    • gnome-keyring is generalized (including SSH keys support and pam_gnome_keyring)
    • Debpkg:system-config-printer replaces gnome-cups-manager

    • Automatic configuration of hotplugged printers (hal-cups-utils)

    • Native "print to PDF" support.
    • new apps : [http://live.gnome.org/Cheese/ cheese], [http://www.gnome.org/projects/vinagre/ vinagre], [http://live.gnome.org/Sabayon sabayon]

    • Improved application evolution, evince, totem (automatic download codecs), gedit (syntax-highlighting), screen-saver (Leave Message feature), Network-manager and power-manager.

    • Many improvements in accessibility support (new applications, at-spi integration in gecko applications)
    • pidgin replace XX

    • gnome-app-install , aka "Add/Remove Applications"

    • Native Flash support, both in the desktop (swfdec-gnome) and in the browser (swfdec-mozilla)

  • X.org 7.3 ~-[http://www.x.org/wiki/Releases/7.3]-~

    • Xserver autoconfiguration (most of xorg.conf becomes useless)
    • RandR 1.2 support on Intel, ATI, and some G80 boards (autodetection of available modes, dynamic resizing, placing and rotating of outputs), but no multiple displays anymore
    • ATI R5xx and R6xx modesetting and 2D acceleration support
  • Openoffice.org 2.4 ~-[http://wiki.services.openoffice.org/wiki/New_Features_2.4]-~

  • Emacs 22
  • Inkscape 0.46

  • gParted 0.36 (can move partitions)
  • Qemu(Kvm)
    • New frontends (qtemu and qemulator)

    • qemu can now use hardware-based virtualization ([#KVM KVM])

    • Rendering uses native widgets
  • KDE 4.1?
  • Iceweasel/Firefox 3 [?]
    • drag and drop tabs across windows

    • gcc/g++ 4.2/4.3 as default C/C++ compiler depending on architecture
    • gfortran 4.3 as default FORTRAN compiler (g77 has been removed)
  • ROOT data analysis package/toolkit, version 5.18, see ["DebianScience/ROOT"]

Debian system

  • Support of symbols files (dpkg-gensymbols, dpkg-shlibdeps)
  • Support of new source package formats (so that they can be used in lenny+1)
  • debhelper 7
  • dpkg triggers
    • Manual page database updated automatically when installing packages
  • apt-get autoremove
  • Usable cross-building support of Debian packages with Debian tools.
  • DebianVolatile is official.

  • kerneloops / kerneloops.org

  • New translations: ...
  • Dropped translations: ...
  • ...

Expected

  • multipath support
  • relatime default

No longer supported in Lenny

Even though the page is called "New" this is probably the best place to track major changes in this category too (after all, the fact that support for something was dropped is new too). -- fjp

Upgrade issues

This section lists (potential) upgrade issues that may need to be documented.

  • [sparc] 2.6.26 kernel does not work with X.Org 7.0/7.1, but should work with 7.3; see [http://lkml.org/lkml/2008/6/3/43 lkml]

  • [i386] Some AMD systems using k7 kernels may end up with non-working kernel after upgrade as replacing pseudo-packages depend on the 686 flavor, but some older k7 systems may not have SSE support. See also: [http://bugs.debian.org/490542 #490542].

Notes

  • a good start would be to review the programs in default tasks + the most installed programs not in tasks.
  • New hardware support ; new modules ?


The layout for this page can have two axis. We'll have to figure out how to write it down at some point :

  1. New vs dropped feature :
    • New stuffs (especially those with high popcon count !)
    • Improved stuff since Etch.
    • Dropped stuffs
    • Deprecated stuffs
  2. Categories
    • Infrastructure, Organization, etc.
    • Architectures.
    • Software Theoretically, we should focus on user features (i.e sysadmin feature). However, considering our audience, we should include a few word on technologies

      • Common software (kernel)
      • Server oriented software.
      • Desktop oriented software.
      • Developer features (esp. DD ?).
      • Other features (embedded, etc.)
    • Miscellaneous (the last but not the least) : Debian Installer, Debian Live, LSB, CDD
