No episode has shown the 8th Doctor's regeneration. He was never in any series of the show, he was in the American made TV movie and in that movie they showed the 7th Doctor regnerate into the 8th, but we don't get to see the 8th regenerate into the 9th Doctor. It goes from the movie, to the revamp in 2005 with the episod Rose where the assumption seems to be that the 9th Doctor is fairly new and possibly recently regenerated.
The Eighth Doctor, played by Paul McGann, only appeared in one episode because he starred in the one-off Doctor Who television movie in 1996 before the series was revived in 2005. The movie was intended to serve as a backdoor pilot for a new series that did not materialize, leaving the Eighth Doctor with just that one on-screen portrayal in the original series.
The Tenth Doctor regenerates in the episode titled "The End of Time," which is a two-part special that serves as his final adventure. The first part aired on December 25, 2009, and the second part on January 1, 2010. In this episode, the Doctor confronts the Time Lord Lord Rassilon and ultimately sacrifices himself to save Wilfred Mott, leading to his regeneration into the Eleventh Doctor.
The 10th Doctor, played by David Tennant, regenerates by absorbing a large amount of radiation while saving Wilfred Mott in the "Doctor Who" episode "The End of Time." This process causes him to regenerate into the 11th Doctor, portrayed by Matt Smith.
