Adobe has renamed the Acrobat products several times, in addition to merging, splitting and discontinuing them. Initially, the offered products were called Acrobat Reader, Acrobat Exchange and Acrobat Distiller. 'Acrobat Exchange' soon became 'Acrobat'. Over time, 'Acrobat Reader' became 'Reader'. Between versions 3 and 5, Acrobat did not have several editions.[clarification needed] In 1999, the Acrobat.com service came to being and introduced several web services whose names started with 'Acrobat', but eventually, 'Acrobat.com' was downgraded from the name of the family of services, to that of one those service.
By 1 April 2015, the Acrobat family consisted of:[24]
Unlike most other Adobe products, such as members of Adobe Creative Suite family, the Acrobat products do not have icons that display two letters on a colored rectangle.
Document Cloud[edit]
In April 2015, Adobe introduced the 'Document Cloud' branding (alongside its Creative Cloud) to signify its adoption of the cloud storage and the software as a service model. Apps under this branding received a 'DC' suffix. In addition, 'Reader' was renamed back to 'Acrobat Reader'.[25][26] Following the introduction of Document Cloud, Acrobat.com was discontinued as their features were integrated into the desktop and mobile apps.
The UI had major changes with the introduction of Acrobat DC in 2015, which supports Windows 7 and later, and OS X 10.9 and later. Version numbers are now identified by the last two digits of the year of major release, and the month and year is specified; the previous version was 12, but examples of the DC (Document Cloud) Acrobat product family versions are DC June 2016, version 15.016.20045, released 2 June 2016 and DC Classic January 2016, version 15.006.30119, released 12 January 2016.[27] From DC 2015 the Acrobat family is available in two tracks, the original track, now named Classic, and the Continuous track.[28] Updates for the Classic track are released quarterly, and do not include new features, whereas updates for the Continuous track are issued more frequently, and implemented silently and automatically.[29]
The last pre-DC version, Acrobat XI, was updated to 11.0.23 version (and this was the final release[30]) on November 14, 2017,[31] support for which ended on October 15, 2017.[32]
As of August 2018, the main members of the Acrobat family include:[33]

From Version 3.02 onwards, Acrobat Reader has included support for JavaScript. This functionality allows a PDF document creator to include code which executes when the document is read. Malicious PDF files that attempt to attack security vulnerabilities can be attached to links on web pages or distributed as email attachments. While JavaScript is designed without direct access to the file system to make it 'safe', vulnerabilities have been reported for abuses such as distributing malicious code by Acrobat programs.[38] Adobe applications had already become the most popular client-software targets for attackers during the last quarter of 2009.[39]McAfee predicted that Adobe software, especially Reader and Flash, would be the primary target for software attacks in the year 2010.[40]
September 2006 warning[edit]
On September 13, 2006, David Kierznowski provided sample PDF files illustrating JavaScript vulnerabilities. Since at least version 6, JavaScript can be disabled using the preferences menu[41] and embedded URLs that are launched are intercepted by a security warning dialog box to either allow or block the website from activating.[42]
February 2009 warning[edit]
On February 19, 2009, Adobe released a Security Bulletin announcing JavaScript vulnerabilities in Adobe Reader and Acrobat versions 9 and earlier.[43] As a workaround for this issue, US-CERT recommended disabling JavaScript in the affected Adobe products, canceling integration with Windows shell and web browsers (while carrying out an extended version of de-integration for Internet Explorer), deactivating Adobe indexing services and avoiding all PDF files from external sources.[44]
February 2013 warning[edit]
Adobe has identified critical vulnerabilities in Adobe Reader and Acrobat XI (11.0.01 and earlier) for Windows and Macintosh, 9.5.3 and earlier 9.x versions. These vulnerabilities could cause the application to crash and potentially allow an attacker to take control of the affected system. Mount and blade fantasy mod. There have been reports of these vulnerabilities being exploited to trick Windows users into clicking on a malicious PDF file delivered in an email message. Adobe recommended users update their product installations.[45]
January 2016 warning[edit]
Adobe has released security updates for Adobe Acrobat and Reader for Windows and Macintosh. These updates address critical vulnerabilities that could potentially allow an attacker to take control of the affected system.[46][47]
