 ## 0.1.2 (unreleased)
 
+New:
+
+* build: `platform_kwargs` defined on the platform will be included in the `platform.prepare()` call.
+* build: timing information from place-and-route shown as part of post-build log.
+
+Changed:
+
+* template: build CXXRTL with optimisations by default in CI
+  (cf. [amaranth-lang/amaranth-yosys#12](https://github.com/amaranth-lang/amaranth-yosys/pull/12)).
+* **XXX** cxxrtl: disabled dependency tracking for now, as it's broken in the important case of
+  source files which depend on the CXXRTL module itself (e.g. those which instantiate it!).
+
 Fixed:
 
 * python: use PDM and declare dependencies correctly.
 * build: use generated IL to calculate digest, not what's on disk.
+* build: synthesis depends on the yosys script too, not just IL.
