 ## [Unreleased]
 ### Changes
+- The features `std_rng`, `sys_rng` and `thread_rng` are now disabled by default ([#1733]).
 - The dependency on `rand_chacha` has been replaced with a dependency on `chacha20`. This changes the implementation behind `StdRng`, but the output remains the same. There may be some API breakage when using the ChaCha-types directly as these are now the ones in `chacha20` instead of `rand_chacha` (#1642).
 - Rename fns `IndexedRandom::choose_multiple` -> `sample`, `choose_multiple_array` -> `sample_array`, `choose_multiple_weighted` -> `sample_weighted`, struct `SliceChooseIter` -> `IndexedSamples` and fns `IteratorRandom::choose_multiple` -> `sample`, `choose_multiple_fill` -> `sample_fill` (#1632)
 - Use Edition 2024 and MSRV 1.85 (#1653)
