Appellant is appealing the denial of his petition for writ of mandamus in which he requested all provisional release credits to which he was entitled. Appellant contends that the ex post facto clause precludes the state from denying him the provisional release credits provided for in section 944.-277, Florida Statutes (1988). The appellant’s contention is without merit. See Dugger v. Rodrick, 584 So.2d 2 (Fla. 1991).

Affirmed.
