Version history

Until October 2010, Lime Wire LLC, the New York City based developer of LimeWire, distributed two versions of the program: a basic free version, and an enhanced version, LimeWire PRO, sold for a fee of US$21.95 with 6 months of updates, or $34.95 with 1 year of updates. The company claimed the paid version provides faster downloads and 66% better search results. This is accomplished by facilitating direct connection with up to 10 hosts of an identical searched file at any one time, whereas the free version is limited to a maximum of 8 hosts.

. The makers of the LimeWire software have now installed a security device that can track most viruses in files.

LimeWire was the first file sharing program to support firewall-to-firewall file transfers, a feature introduced in version 4.2, which was released in November 2004. LimeWire also now includes BitTorrent support, but is limited to 3 Torrent uploads and 3 Torrent downloads, which coexist with ordinary downloads. As of LimeWire 5.0, an instant messenger has been added which uses the XMPP Protocol, an open source communication protocol. Users can now chat and share files with individuals or a group of friends in their buddy list.

From version 5.5.1, LimeWire has added a key activation, which requires the user to enter the unique key before activation the "Pro" version of the software. This has stopped people from illegally downloading the "Pro" versions. However, there are still ways to bypass this security, for example, there are currently cracks on the internet, or people remain using LimeWire Pro 5.5.1 Beta which also includes AVG for LimeWire and is the first version to include AVG. The most recent stable version of LimeWire is 5.5.16.

Versions of LimeWire prior to 5.5.10 can still connect to the Gnutella network and users of these versions are still able to download files, even though a message is displayed concerning the injunction during the startup process of the software. LimeWire versions 5.5.11 and newer feature an auto-update feature that allowed Lime Wire LLC to disable newer versions of the LimeWire software. Older versions of LimeWire prior to version 5.5.11 however do not include the auto-update feature and are still fully functional. As a result, neither the RIAA nor Lime Wire LLC have the ability to disable older versions of LimeWire, unless the user chooses to upgrade to a newer version of LimeWire.

On November 10, 2010, a secret group of developers called the "Secret Dev Team" sought to keep the service running by releasing the "LimeWire Pirate Edition". It appeared on several torrent websites. The software is based on LimeWire 5.6 Beta, and is aimed to allow Windows versions to still work and remove the threat of spyware or adware. The exclusive features in LimeWire PRO were also unlocked, and all security features installed by Lime Wire LLC were removed.

. When eventually activated, the code could block its users from sharing licensed files. This code was recently changed when lawsuits had been filed against LimeWire for p2p downloading. It had blocked all their users and redirected them to FrostWire.

It is unclear how WireShare, and thus LimeWire Pirate Edition, differ from FrostWire, also with the purpose of removing malware and backdoors.

Criticism

On February 15, 2010, LimeWire reversed its previous anti-bundling stance and announced the inclusion of an Ask.com-powered browser toolbar which must be explicitly opted-out to prevent installation. The toolbar sends web and bittorrent searches to Ask.com, and LimeWire searches to an instance of LimeWire on the user's machine.

In LimeWire versions before 5.0, users could accidentally configure the software to allow access to any file on their computer, including documents with personal information. Recent versions of LimeWire do not allow unintentional sharing of documents or applications. In 2005, the US Federal Trade Commission issued a consumer warning regarding the dangers of using peer-to-peer file sharing

. The ability to distribute such malware and viruses has also been reduced in versions of LimeWire 5.0 and greater, with the program defaulting to not share or search for executable files.

. Among other things, LimeShop monitored online purchases in order to redirect sales commissions to Lime Wire LLC. Uninstallation of LimeWire would not remove LimeShop. With the removal of all bundled software in LimeWire 3.9.4 (released on April 20, 2004), these objections were addressed. LimeWire currently has a facility that allows its server to contact a running LimeWire client and gather various information.

. According to federal prosecutors, Kopiloff used LimeWire to search other people's computers for inadvertently shared financial information and then used it to obtain credit cards for an online shopping spree.

LimeWire automatically receives a cryptographically signed file, called simpp.xml, containing an IP block list. Blocking certain IPs has become commonplace and even considered essential in P2P filesharing.

.

In response to the ruling, a company spokesperson said that the company is not shutting down, but will be using its "best efforts" to cease distributing and supporting P2P software.

Recently, the RIAA announced their intention to sue LimeWire for $75 trillion in damages - a sum greater than the current GDP of the entire global economy. There are currently around 11,000 songs on LimeWire that have been tagged as copyright-infringed, and the RIAA estimates that each one has been downloaded thousands of times, the penalties accruing to the above sum.

A trial to decide on the eventual amount of damages owed by Limewire to thirteen record labels, including Warner and Sony Music, all of which are represented by the Recording Industry Association of America (RIAA), started early in May and went on until on May 13, 2011, when Gorton agreed to pay the 13 record companies $105 million in an out-of-court settlement.

Mitch Bainwol, chairman of the RIAA, referred to the “resolution of the case [as] another milestone in the continuing evolution of online music to a legitimate marketplace that appropriately rewards creators.”
