- Fixes were made for suppression of PHP notices, reloading and previewing of plain text mailings, loading of sample data from the support library, WYSIWYG Editor mangling of URLs, bandwidth throttle calculations, throttle setting limitations, and typographical errors.

squid-filter project was designed to build filtering capabilities comparable to those of Muffin into Squid. It consists of
a patch to Squid, containing a module loader and filtering hooks, and a set of filter modules.
Currently available filters:
- Redirection of URIs.
- Rejection of certain (configurable) MIME content types.
- Suppression of cookies.
- Removal of Javascript and ActiveX.
- Breaking of GIF animation loops.
- Detection of 1x1 images.
Main features:
- Modular, easily extensible by writing new filters.
- Flexible configuration. Filters are independent from each other.
- Each filter can take a list of URIs which should not be filtered (allow list). URIs are specified as full regular expressions.
- Client can choose to bypass filters case-by-case.
- Filtering keeps Content-Length where possible.
Purpose
A filtering proxy allows users to remove unwanted stuff from Web pages as they browse them. What "unwanted stuff" is obviously depends on the individual user, but things which are commonly regarded as annoyances include
banner ads, user behaviour tracking via cookies,
animated pictures, JavaScript, VBScript, ActiveX (dangerous as well as annoying).
Some of those things can be avoided by filtering URIs, which Squid can already do via an external redirect program. Others require a content filter.
Usually, a filtering proxy runs standalone and does nothing but filtering. Users have to configure this proxy in their browsers, and if they use a caching proxy too, chain them after the filter. In situations where the user runs Squid anyway (mostly because of caching for different browsers or a small LAN), it is convenient to build this capability into Squid.

"mdnsd" is a very lightweight, simple, portable, and easy to integrate open source implementation of Multicast DNS (part of Zeroconf, also called Rendezvous by Apple) for developers. It supports both acting as a Query and a Responder, allowing any software to participate fully on the .localnetwork just by including a few files and calling a few functions. All of the complexity of handling the Multicast DNS retransmit timing, duplicate
suppression, probing, conflict detection, and other facets of the DNS protocol is hidden behind a very simple and very easy to use interface, described in the header file. The single small c source file has almost no dependencies, and is portable to almost any embedded platform. Multiple example applications and usages are included in the download, including a simple very persistent query browser and a tool to advertise local web sites.


The code is licensed under both the GPL and BSD licenses, for use in any free software or commercial application. If there is a licensing need not covered by either of those, alternative licensing is available upon request.

mdns-scan is a tool for scanning for mDNS/DNS-SD published services on the local network. mdns-scan issues a mDNS PTR query to the special RR _services._dns-sd._udp.local for retrieving a list of all currently registered services on the local link.
mdns-scan is not a good mDNS citizen since it queries continuously for services and doesnt implement features like Duplicate Suppression. It is intended for usage as a debugging tool only.
mdns-scan is incomplete since it doesnt resolve mDNS services for you - it just dumps their PTR RRs. To understand these records you need minimal knowledge of DNS-SD and how it works.
mdns-scan does not terminate on its own behalf. It scans for services continuously until the user kills it by pressing C-c.
mdns-scan does not rely on a local mDNS responder daemon. It has no dependencies besides the GNU libc. It has been tested on Linux only.
mdns-scan does NOT scan for local mDNS enabled hosts or A/AAAA RRs, it scans for DNS-SD registered services, nothing else.
Enhancements:
- Add man pages
- Improvements to the Debianization
