Changes includedare listed below. ****************************************************** *Mirror* is a new user contributed new video plugin and has been documented in the Manual. *Gain *audio plugin has been improved to include the text box for precise designation of the gain and the clear/reset button to revert to the default. This was a user contribution. *Andrew contributions include:* The *About* in the Settings→Preferences now shows the Copyright to include the Cinelerra-GG team, the previous Cinelerra-CV team, as well as the libav version.
