Kernel and utilities

Linux 2.6.26 ( see KernelFAQ#new-features-in-lenny );

lspci (pciutils 3.0.0) has a -Q option to query the central database.

mount : read-only binds ; --make-shared, --make-slave, --make-private, --make-unbindable

KVM (kernel + qemu-kvm...)

ntfs-3g (i.e R-W support) gnome expects ntfs-3g to mount volumes, which isn't installed by default so it fails. Is there a regression here ? (needs testing).

List of Discontinued/Renamed modules. Most legacy CD (pre IDE!): aztcd, gscd isp16, mcdx optcd sjcd sonycd535 (Old CD-ROM drivers not SCSI, not IDE)



Removed

No support for Linux 2.4

Desktop

GNOME 2.22 ( 2.22 release notes 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) system-config-printer replaces gnome-cups-manager mlocate replace locate, content is now indexed. Automatic configuration of hotplugged printers (hal-cups-utils) Improved CD/DVD ISO support (Archive Manager can open an ISO ; nautilus-cd-burner can burn it.) new apps : cheese, vinagre, sabayon Improved application evolution, evince, totem (automatic download codecs), gedit (syntax-highlighting), screen-saver (Leave Message feature), Network-manager and power-manager. Improved Internationalization. Many improvements in accessibility support (new applications, at-spi integration in gecko applications) pidgin replace gaim gnome-app-install , aka "Add/Remove Applications" Native Flash support, both in the desktop (swfdec-gnome) and in the browser (swfdec-mozilla)

LXDE

removed

EVMS

NAS

Support for Marvell's Orion platform. Specifically, lenny supports the following devices based on the Orion platform: QNAP Turbo Station (TS-109, TS-209, TS-409), HP mv2120, and Buffalo Kurobox Pro.

Security

Besides the regular Debian security support for the full archive, Lenny introduces pro-active security features to preemptively reduce the chance on vulnerabilities:

Debian Installer now applies any security updates before the first boot.

Several security-critical packages have been built with GCC Hardening features. TODO: list.

The standard system contains fewer setuid root binaries and fewer open ports.

Various applications have added hardening improvements specific to their application. For example, PHP is now built with the Suhosin hardening patch.



Programming

Python 2.5 as the default Python interpreter

Tcl/Tk 8.5

Perl 5.10

GCC 4.3 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

'aptitude safe-upgrade' replaces 'aptitude upgrade'

'aptitude full-upgrade' replaces 'aptitude dist-upgrade'

Usable cross-building support of Debian packages with Debian tools.

DebianVolatile is official.

?Kernel/Oops / kerneloops.org (pic)

Grub2 uses root=${UUID}, to on new installed systems.

Other boot changes: kexec+readahead+insserv+dash can give faster boot

Packages

List of New, Removed and Upgraded packages, see

http://www.klabs.be/~fpiat/linux/comp-dist/lenny/

Debian Installer

Only major changes are listed. For details the various release announcements can be checked.

Support for multiple CDs/DVDs during the installation

Update of system clock using NTP

Experimental support for SATA RAID (dmraid)

relatime mount option (see mount(1)).

isolinux boot menu (i386/amd64)

Option to install Debian from MS Windows (i386/amd64)

Various changes affecting automated installs (preseeding)

New hardware support: ...

New translations: ...

Dropped translations: ...

...

Prompts for a media with required non-free firmware, if required.

BluRay installation images for i386 and amd64.

multipath support (multipath-modules)

possibility to add volatile.debian.org to sources.list (by pre-seeding)

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

Architecture : sparc32

Packages : Debian tools that are removed : Linda. Removed packages, with no equivalent that " Provides " transition. (a list, as of 2008-05-30) apache v1 (superseded by apache2) xmms v1 (superseded by xmms2) FlashPlayer only available as a backport, but swfdec-mozilla is installed by default.

Firmware : the following firmwares have been removed from Debian main.

This particularly affects network cards (which might be required for a net-install). In order to activate affected devices, the 'non-free' section has to be enabled.

Todo: add link to documentation for new installations; add list of affected firmware -- jw

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 lkml

On system with nfs, nfs-common MUST be upgraded before mount see #493095

As of 2.6.25 (and still in 2.6.26 in lenny), megraid_mbox kernel panics if you have non-RAID devices on the PERC3/DC RAID controller and possibly other Dell PERC3 models, see #490903

Upgrading over ssh when the connection is managed by NetworkManager can lead the upgrade failing/hanging when the NetworkManager service is restarted. If you are lucky, the ssh connection will not drop out; if you are unlucky, the ssh connection will drop out and at the next interactive point in the upgrade (e.g. dpkg "replace this file" or debconf) the entire upgrade is left in a horrible state.

bind9 no longer allows recursive queries by default; you may need to add allow-query { any; }; to named.conf to get the previous behavior. There are also many configuration file changes; see LennyBind9 for details.

lprng no longer listens on a TCP socket by default; you may need to add lpd_listen_port=515 to lpd.conf to get the previous behavior.

For certain network interfaces, the means of specifying speed/duplex settings may change. You may need to install the ethtool package and use it in place of mii-tool in some setups.

courier-imap logins may fail with the (incorrect) error message "Account's mailbox directory is not owned by the correct uid or gid", which can be prevented by setting IMAP_MAILBOX_SANITY_CHECK to 0 in /etc/courier/imapd .

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 axes. We'll have to figure out how to write it down at some point :

New vs dropped feature : New stuffs (especially those with high popcon count !) Improved stuff since Etch. Dropped stuffs Deprecated stuffs Changes in DFSGfreeness - alpine, openjdk, djbdns, ttf-liberation in main

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
