 // Package rand implements pseudo-random number generators.
 //
-// Random numbers are generated by a Source. Top-level functions, such as
-// Float64 and Int, use a default shared Source that produces a deterministic
-// sequence of values each time a program is run. Use the Seed function to
-// initialize the default Source if different behavior is required for each run.
-// The default Source, a LockedSource, is safe for concurrent use by multiple
-// goroutines, but Sources created by NewSource are not. However, Sources are small
-// and it is reasonable to have a separate Source for each goroutine, seeded
-// differently, to avoid locking.
-//
 // For random numbers suitable for security-sensitive work, see the crypto/rand
 // package.
+//
+// Deprecated: use the math/rand/v2 package instead. This package is
+// scheduled to be tagged and deleted, per https://go.dev/issue/61716.
