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
- GNOME has been updated to version 3.x.
- KDE has been updated to version 4.8
- 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- In Debian wheezy, ffmpeg has been replaced by the libav fork, which is considered to feature a more conservative release process and thus fit better to Debian's needs.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)
kfreebsd and Hurd ports use XFCE by default (? see http://lists.debian.org/debian-bsd/2011/09/msg00051.html)
Server
Xen Cloud Platform (XCP)
Openstack
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
Two factor authentication (tokens) - Debian now provides a comprehensive, open and free alternative to the pervasive RSA tokens that have recently been compromised
liboath0 provides a foundation for Open Authentication (OATH) techniques/algorithms such as HOTP and TOTP
dynalogin-server provides an advanced and robust client/server framework for implementing OATH and storing credentials securely
simpleid-store-dynalogin provides a practical way to combine OpenID for single-sign-on (SSO) with OATH
yubiserver provides another advanced client/server framework for implementing OATH, supporting the USB-based ?YubiKey
oathtool provides a command line test utility for the OATH algorithms
Programming
- 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
Debian Installer
WPA support
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.
