The Doctor's Restoration lifecycle

By one account of the Last Great Time War, the Eighth Doctor was given a reset lifecycle of regenerations by the Restoration.

After the Doctor used the Moment in the final event, he knew he could no longer regenerate. The Eighth Doctor's life was the Doctor's last life of the Doctor's regenerations, and the Moment had fixed his existence. However, the Doctor's saviour had given her life to give him the Restoration, which reset his lifecycle. The Eighth Doctor's regeneration was the first of this reset lifecycle, and it was the first time the Doctor regenerated with a golden glow. (PROSE: Doctor Who and the Time War)

The Doctor's later regenerations, including the Ninth Doctor's regeneration, the Tenth Doctor's siphoned regeneration, and the Tenth Doctor's regeneration, all had the distinctive golden glow (TV: The Parting of the Ways, The Stolen Earth, The End of Time) which came from this new lifecycle.
