-# Unreleased

-* Add `Value` and `Type` constructors for variable-length buffers and SHA256 `Ctx8` contexts;
-  change the signature of `Final::two_two_n` to return a result rather than panicking when `n`
-  is too large; add infallible `Final::two_two_n_fixed` for when `n` is known at compile-time

+* Avoid exponential work during type finalization and stack overflows when dropping deeply nested
+  nodes and incomplete types [#375](https://github.com/BlockstreamResearch/rust-simplicity/pull/375)
+* Upgrade `elements` to 0.27 and `bitcoin_hashes` to 1.2, requiring `simplicity-sys` 0.7.1 [#376](https://github.com/BlockstreamResearch/rust-simplicity/pull/376)
+  * Remove the policy `Assembly` fragment and make policy serialization infallible.
+  * Fold `JetConstructible` into `CoreConstructible`.
+  * Remove the unused tapleaf hash argument from policy signature lookup.
