+## 2.0.0
+
+Unreleased.
+
+### Added
+
+* Cranelift has gained support for forward-edge CFI on the AArch64 backend.
+  [#3693](https://github.com/bytecodealliance/wasmtime/pull/3693)
+
+* A `--disable-parallel-compilation` CLI flag is now implemented for `wasmtime`.
+  [#4911](https://github.com/bytecodealliance/wasmtime/pull/4911)
+
+* [Tier 3] support has been added for for RISC-V 64 with a new backend in
+  Cranelift for this architecture.
+  [#4271](https://github.com/bytecodealliance/wasmtime/pull/4271)
+
+* Basic [tier 3] support for Windows ARM64 has been added but features such as
+  traps don't work at this time.
+  [#4990](https://github.com/bytecodealliance/wasmtime/pull/4990)
+
+### Changed
+
+* The implementation of the `random_get` function in `wasi-common` is now faster
+  by using a userspace CSPRNG rather than the OS for randomness.
+  [#4917](https://github.com/bytecodealliance/wasmtime/pull/4917)
+
+* The AArch64 backend has completed its transition to ISLE.

+  [#4943](https://github.com/bytecodealliance/wasmtime/pull/4943)
+
+* The size of the `sigaltstack` allocated per-thread for signal handling has
+  been increased from 16k to 64k.
