OS Infrastructure

  • ext4 is now the default filesystem for new Linux installations. It is possible to convert an ext3 Filesystem to ext4, following this Howto.

  • As an option: systemd: with journald, utilizing new kernel feature cgroups, and exposing other new kernel features like per-process filesystem namespaces.

Desktop and Laptop

  • 2011-06-23: LibreOffice replaces OpenOffice.org, see announcement; (702039)

  • GNOME has been updated to version 3.4.
  • KDE has been updated to version 4.8
  • XFCE has been updated to version 4.8
  • PackageKit replaces the previous graphical package management stack on GNOME

  • Multimedia support
    • In Debian wheezy, ffmpeg has been replaced by the libav fork, which is considered to feature a more conservative release process and thus fit better to Debian's needs. It provides all libraries and prepares an upgrade path for existing application packages.
    • Debian wheezy comes with full-featured libav (formerly ffmpeg) libraries and frontends, including e.g. mplayer, mencoder, vlc and transcode. Additional codec support is provided e.g. through lame for MP3 audio encoding, xvidcore for MPEG-4 ASP video encoding, x264 for H.264/MPEG-4 AVC video encoding, vo-aacenc for AAC audio encoding and opencore-amr and vo-amrwbenc for Adaptive Multi-Rate Narrowband and Wideband encoding and decoding, respectively. For most use cases, installation of packages from third-party repositories should not be necessary anymore. The times of crippled multimedia support in Debian are finally over!

  • Real-time kernel featureset (linux-image-rt-amd64, linux-image-rt-686-pae)

Server

Cloud

(get in touch with debian-cloud for more info/references about this)

Deploy your own cloud using Debian

  • Xen Cloud Platform (XCP)

  • Openstack

Use Debian on public clouds

  • Amazon EC2
  • Windows Azure
  • Google Computer Engine

Communications

  • Better support for UnifiedCommunications and Federated VoIP:

    • previous releases of Debian had excellent support for VoIP (SIP and Jabber) within a single site
    • Wheezy includes a range of independent components that enable federation and routing between sites
    • reTurn server provides ICE/STUN/TURN to enable NAT traversal for sites using SIP, Jabber or both

    • repro SIP proxy provides mutual TLS for federated SIP calling (packages like ejabberd already provide federation for Jabber users)

    • dlz-ldap-enum uses the phone numbers and email addresses in LDAP directories to support routing of SIP or Jabber over large sites or distributed/loosely-coupled organisations

Security

Programming

  • Perl 5.14 (703561)

  • Python 2.7 as the default Python 2.X interpreter (2.6 remains supported)
  • Python 3.2 as the default Python 3.X interpreter
  • Ruby - 1.9 as default version, 1.8 still available, but will be dropped in Wheezy+1

  • Haskell - GHC 7.4.1

  • Lua - Lua 5.2 joins Lua 5.1.

Debian Installer

  • Support for UEFI installation on x86-64 (amd64) systems
  • WPA support

  • Software speech synthesis support!
  • Support for installing to diskless systems using ?NBD or ?iSCSI.

Debian Pure Blends

The Debian subsets targeting at specific user groups which were formerly known as Custom Debian Distributions are now called Debian Pure Blends (in short Blends). New Blends featuring metapackages in Wheezy are : none yet

Debian Med

New packages of specific importance

  • ginkgocadx: industrial strength,field-tested medical image (DICOM) viewer fit for use in the busy daily practice of Medicine.
  • hhsuite: sensitive protein sequence search tool based on the pairwise alignment of hidden Markov models. hhsuite compares favorably to the NCBI PSI-BLAST according to the authors.
  • reprof: protein secondary structure and accessibility predictor that improves on the popular PROF (packaged as profphd) tool.
  • biosig4c++: supports over 40 formats for biomedical signal data (EEG, ECG, etc.
  • freediams: pharmaceutical drug prescription and interaction manager
  • freemedforms-emr: electronic medical record manager
  • other packages to mention here

Debian Science

and the other sciences oriented Blends DebianMed and ?DebiChem started maintaining citation information that is displayed in the web sentinel and can be used in a BibTeX file.

FOSS solutions for various fields of science got vastly improved coverage

  • Neuroscience
    • Modeling: brian, pynn
    • Electrophysiology: aghermann, eegdev, klustakwik, sigviewer, stimfit
    • Brain imaging: cmtk, connectomeviewer, dipy, mricron, nitime, openwalnut, pysurfer
    • Psychophysics: psychtoolbox-3, psignifit3
    • Data I/O: biosig4c++, nibabel, libgdf, neo
    • Hardware interfaces: libfreenect, pyoptical, pyxid
  • ADD YOUR FIELD

with new software addressing miscelaneous computing demands

  • Distributed computing
    • cctools, condor, dmtcp, mpi4py
  • Remote access: guacamole
  • General numeric computing
    • numexpr, pandas, skimage, statsmodels, xppaut (maintained again)
  • IPython 0.13 with notebook support
  • Other helpful tools: CDE (cdepack), numdiff

although not an explicit release goal -- many of the above packages enabled exercising of upstream's unittest batteries at build-time -- that greatly improved reliability and guaranteed performance of the scientific software in Debian.

No longer supported in Wheezy

none yet

  • uw-imapd or ipopd daemons: Code is in bad shape and better alternatives exist. In particular dovecot is recommended as replacement, being equally (if not more) compliant with IMAP RFCs and thoroughly tested with transitions from uw-imap.
