I2P is an anonymizing network, offering a simple layer that identity-sensitive applications can use to securely communicate. All data is wrapped with several layers of encryption, and the network is both distributed and dynamic, with no trusted parties.

Many applications are available that interface with I2P, including mail, peer-peer, IRC chat, and others.

Major Features:

1. The I2P project was formed in 2003 to support the efforts of those trying to build a more free society by offering them an uncensorable, anonymous, and secure communication system.
2. I2P is a development effort producing a low latency, fully distributed, autonomous, scalable, anonymous, resilient, and secure network. The goal is to operate successfully in hostile environments. even when an organization with substantial financial or political resources attacks it.
   
3. All aspects of the network are open source and available without cost, as this should both assure the people using it that the software does what it claims, as well as enable others to contribute and improve upon it to defeat aggressive attempts to stifle free speech.
4. Anonymity is not a boolean. I2P is a low latency mix network, and there are limits to the anonymity offered by such a system, but the applications on top of I2P, such as I2P mail, and I2PSnark extend it to offer both additional functionality and protection.
5. I2P is still a work in progress. It should not be relied upon for "guaranteed" anonymity at this time, due to the relatively small size of the network and the lack of extensive academic review. It is not immune to to attacks from those with unlimited resources, and may never be, due to the inherent limitations of low-latency mix networks.

Enhancements:

• I2P version 0.7.5 foremost addresses network stability issues by adjusting how exploratory tunnels are built if a router nears its connection limit, and also by distinguishing between connected peers and other non-failing peers while picking them for inclusion in tunnels.
• This version also delivers fixes to installer behaviour on Windows, to the Router Console, NTCP transport and UPnP mechanism.
• Additionally, version 0.7.5 changes the "news.xml" file location where I2P routers check whether a new version is available. Instead of the old URL a new location will be used. If your router uses default updater settings, it will start using the new URL automatically. If not, you will need to visit "configupdate.jsp" on the Router Console, and change it manually.
• For a while after this update, the old news.xml location also redirects all HTTP requests to the new one.

The name Nmap stands for Network Mapper. Nmap was designed to be a free utility for network exploration or security auditing.
Many systems and network administrators also find it useful for tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime.
Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics.
It was designed to rapidly scan large networks, but works fine against single hosts. Nmap runs on all major computer operating systems, and both console and graphical versions are available.
Main features:
- Flexible: Supports dozens of advanced techniques for mapping out networks filled with IP filters, firewalls, routers, and other obstacles. This includes many port scanning mechanisms (both TCP & UDP), OS detection, version detection, ping sweeps, and more. See the documentation page.
- Powerful: Nmap has been used to scan huge networks of literally hundreds of thousands of machines.
- Portable: Most operating systems are supported, including Linux, Microsoft Windows, FreeBSD, OpenBSD, Solaris, IRIX, Mac OS X, HP-UX, NetBSD, Sun OS, Amiga, and more.
- Easy: While Nmap offers a rich set of advanced features for power users, you can start out as simply as "nmap -v -A targethost". Both traditional command line and graphical (GUI) versions are available to suit your preference. Binaries are available for those who do not wish to compile Nmap from source.
- Free: The primary goals of the Nmap Project is to help make the Internet a little more secure and to provide administrators/auditors/hackers with an advanced tool for exploring their networks. Nmap is available for free download, and also comes with full source code that you may modify and redistribute under the terms of the license.
- Well Documented: Significant effort has been put into comprehensive and up-to-date man pages, whitepapers, and tutorials. Find them in multiple languages here.
- Supported: While Nmap comes with no warranty, it is well supported by a vibrant community of developers and users. Most of this interaction occurs on the Nmap mailing lists. Most bug reports and questions should be sent to the nmap-dev list, but only after you read the guidelines. We recommend that all users subscribe to the low-traffic nmap-hackers announcement list.
- Acclaimed: Nmap has won numerous awards, including "Information Security Product of the Year" by Linux Journal, Info World and Codetalker Digest. It has been featured in hundreds of magazine articles, several movies, dozens of books, and one comic book series. Visit the press page for further details.
- Popular: Thousands of people download Nmap every day, and it is included with many operating systems (Redhat Linux, Debian Linux, Gentoo, FreeBSD, OpenBSD, etc). It is among the top ten (out of 30,000) programs at the Freshmeat.Net repository. This is important because it lends Nmap its vibrant development and user support communities.

System requirements:
- WinPcap 4.x+

Enhancements:
- [Zenmap] Removed services.dmp and os_dmp.dmp and all the files that referred to them. They are not needed with the new search interface. Also removed an unused search progress bar. And some broken fingerprint submission code.
- [Zenmap] Added "%F" to the Exec link in the new Zenmap desktop file. We expect (hope) that this will allow dragging and dropping XML files onto the icon.
- [Zenmap] The -o[XGASN] options can now be specified, just as you can at the console.
- [Zenmap] You can now shrink the scan window below its default size thanks to NmapOutputViewer code enhancements.
- [Zenmap] Removed optional use of the Psyco Python optimizer since Zenmap is not the kind of CPU-bound application which benefits from Psyco.
- [Zenmap] You can now select more than one host in the "Ports / Hosts" view by control-clicking them in the column at left.
- [Zenmap] The profile editor now offers the --traceroute option.
- Zenmap now uses Unicode objects pervasively when dealing with Nmap text output, though the only internationalized text Nmap currently outputs is the users time zone.
- Unprintable characters in NSE script output (which really shouldnt happen anyway) are now printed like xHH, where HH is the hexadecimal representation of the character.
- Nmap sometimes sent packets with incorrect IP checksums, particularly when sending the UDP probes in OS detection. This has been fixed. Thanks to Gisle Vanem for reporting and investigating the bug.
- Fixed the --without-liblua configure option so that it works again.
- In the interest of forward compatibility, the xmloutputversion attribute in Nmap XML output is no longer constrained to be a certain string ("1.02"). The xmloutputversion should be taken as merely advisory by authors of parsers.
- Zenmap no longer leaves any temporary files lying around. Nmap only prints an uptime guess in verbose mode now, because in some situations it can be very inaccurate.

Dict will define the words you select from a webpage. In order to define theese words, Dict will use different sources.

Main features:
- A "define selection" pop-up menu item that defines the selected word.
- When no definitions are found, a page of nearest matches is returned.
- When only one nearest match is found, its definition is returned.
- Can be configured to use a user-selected server. Depending on the chosen server, the extension can be used to define words in other languages and/or translate words from one language to another.
- Rudimentary support for the "dict" URI scheme

System requirements:
- Firefox: 1.0 - 3.0.*

Enhancements:
- Marked as compatible with Firefox 3.0.1.
- Fixed a window sizing problem on Firefox 3.0.1.
- Mitigated an incompatibility with the Menu Editor addon.
