In June 2017, Google announced the upcoming end to the use of contextual Gmail content for advertising purposes, relying instead on data gathered from use of its other services.
In October 2012, Google added over 100 virtual keyboards, transliterations, and input method editors to Gmail, enabling users different types of input styles for different languages in an effort to help users write in languages that aren't "limited by the language of your keyboard.” Gmail's "basic HTML" version will work on almost all browsers.
Major redesigned elements included a streamlined conversation view, configurable density of information, new higher-quality themes, a resizable navigation bar with always-visible labels and contacts, and better search.
Users were able to preview the new interface design for months prior to the official release, as well as revert to the old interface, until March 2012, when Google discontinued the ability to revert and completed the transition to the new design for all users.
In addition to customization options, the entire update can be disabled, allowing users to return to the traditional inbox structure.
In April 2018, Google introduced a new web UI for Gmail, available by opt-in for all Gmail users.
Users can receive emails up to 50 megabytes in size, including attachments, while they can send emails up to 25 megabytes.
