dual-format edition, and the decision was reversed to release separate discs for titles beginning in September 2014. Despite the emergence of Blu-ray as the industry-standard high-definition format, Janus/Criterion continues to support the DVD format. Not only are all their new Blu-ray releases accompanied by a standard-definition DVD version, but revised and upgraded releases are also released on both formats (barring the brief foray into dual-format releases). Moreover, the company's standalone line of Eclipse releases are currently only made available in the standard DVD format. Aside from the core catalog, the company has also released films through its Essential Art House, Eclipse and Merchant Ivory Collection lines, as well as a few releases outside of any product line. Many of these releases have also been collected and sold in various box sets. In April 2016 for the first time in its history, Criterion announced it would begin releasing its catalogue outside of the U.S. (earlier international Criterion titles such as the Japanese LaserDisc of Blade Runner were licensed to other companies). In partnership with Sony Pictures Home Entertainment, releases began to be distributed with the launch of six titles in the U.K. during the month. Blu-ray Criterion began publishing titles on Blu-ray Disc in December 2008. Unlike its DVD releases, which are a mixture of NTSC-standard Region 0 (region-free) and Region 1 DVDs, Criterion Collection Blu-ray discs are Region A-locked in North America or Region B-locked in the United Kingdom (though there are exceptions). Ultra HD Blu-ray On August 11, 2021, Criterion announced that it would begin publishing titles in Ultra HD Blu-ray format in November 2021. All Criterion Ultra HD Blu-ray releases will include both an Ultra HD Blu-ray copy and a regular Blu-ray copy of a film (with all the special features on the regular Blu-ray), with select releases including Dolby Vision HDR and Dolby Atmos. The first such releases were announced on August 16 for a November 21 release: Citizen Kane (returning to the collection for the first time since 1992), Mulholland Drive and Menace II Society. The company also plans to release The Red Shoes, A Hard Day’s Night and The Piano on Ultra HD Blu-ray disc. The film Uncut Gems, which was previously planned for Blu-ray and DVD release in October 2021, was delayed until November in order to also give the film an Ultra HD Blu-ray release. Eclipse Eclipse is a line started in 2007
