 ### Added
 
+* Allow the MPL-2.0 and OpenSSL licenses in dependencies of wasmtime.
+  [#6136](https://github.com/bytecodealliance/wasmtime/pull/6136)
+
+* Add a bounds-checking optimization for dynamic memories and guard pages.
+  [#6031](https://github.com/bytecodealliance/wasmtime/pull/6031)
+
+* Add support for generating perf maps for simple perf profiling. Additionally,
+  the `--jitdump` and `--vtune` flags have been replaced with a single
+  `--profile` flags that accepts `perfmap`, `jitdump`, and `vtune` arguments.
+  [#6030](https://github.com/bytecodealliance/wasmtime/pull/6030)
+
+* Validate faulting addresses are valid to fault on. As a mitigation to CVEs
+  like `GHSA-ff4p-7xrq-q5r8`, check that the address involved in a fault is one
+  that could be contained in a `Store`, or print a scary message and abort
+  immediately.
+  [#6028](https://github.com/bytecodealliance/wasmtime/pull/6028)
+
+* Add the `--default-values-unknown-imports` option to define unknown function
+  imports as functions that return the default value for their result type.
+  [#6010](https://github.com/bytecodealliance/wasmtime/pull/6010)
+
+* Add `Clone` for `component::InstancePre`.
+  [#5996](https://github.com/bytecodealliance/wasmtime/issues/5996)
+
+* Add `--dynamic-memory-reserved-for-growth` cli flag.
+  [#5980](https://github.com/bytecodealliance/wasmtime/issues/5980)
+
+* Introduce the `wasmtime-explorer` crate for investigating the compilation of
+  wasm modules. This functionality is also exposed via the `wasmtime explore`
+  command.
+  [#5975](https://github.com/bytecodealliance/wasmtime/pull/5975)
+
+* Added support for the Relaxed SIMD proposal.
+  [#5892](https://github.com/bytecodealliance/wasmtime/pull/5892)
+
+* Cranelift gained many new machine-independent optimizations.
+  [#5909](https://github.com/bytecodealliance/wasmtime/pull/5909)

 ### Changed
 
+* Derive `Copy` on `wasmtime::ValType`.
+  [#6138](https://github.com/bytecodealliance/wasmtime/pull/6138)
+
+* Make `StoreContextMut` accessible in the epoch deadline callback.
+  [#6075](https://github.com/bytecodealliance/wasmtime/pull/6075)
+
+* Take SIGFPE signals for divide traps on `x86_64`.
+  [#6026](https://github.com/bytecodealliance/wasmtime/pull/6026)
+
+* Use more specialized AVX instructions in the `x86_64` backend.
