Google has finally brought the Gboard which came to iOS six-months ago, to Android devices. It is named Google Keyboard and should replace your current Android Google Keyboard.

Google listed these as the new features:

Themes: Customize keyboard with favorite photos or colors

Layout support: Burmese, Southern Sotho, Turkmen, Urdu, Welsh, Xhosa
Add recent emoji to suggestion strip
Bug fixes, including passwords with Talkback and missing key labels

Android Police documented these changes:

G button (enabled in settings) offers quick access to search from the keyboard
Pop-out toolbar (when G button not enabled) provides access to themes, settings, one-handed mode, and search
Optional dedicated number row
Up to three active languages with preference for one (previously had to switch)
Gesture typing is now called Glide typing.
