+
+## Bug fixes
+
+- Fix matrix lists for output.
+
+## Features
+
+- Add `invalidate_cache()` to R interface (#1387, #2416).
+
+- All arguments in calls to `_impl()` functions are named (#2423).
+
+## Chore
+
+- Use `Rx_` prefix for manually generated functions.
+
+- Clarify error testing preference \[ci skip\].
+
+- Ignore \[ci skip\].
+
+- Use `_impl` variants instead of inline `.Call()` for five functions with changed C signatures (#2428, #2429).
+
+- Format \[ci skip\].
+
+- Expand remaining `_impl` aliases (#2422).
+
+- Remove unused `NTIMER` and `NPRINT` macro definitions (#1095, #2405).
+
+- Cleanup.
+
+- Request math notation.
+
+### deps
+
+- Bump jinja2 from 3.1.2 to 3.1.6 in /tools/py-stimulus (#2401).
+
+- Replace `_impl` aliases in `R/flow.R` (#2347, #2379).
+
+- Autogenerated file looks more like as if it was formatted with `air` (#2395).
+
+## Continuous integration
+
+- Run daily vendoring to avoid noise \[ci skip\].
+
+- Snapshots \[ci skip\].
+
+- Use proper actor name \[ci skip\].
+
+- Reduce contention by running big matrices overnight.
+
+- Add workflow to auto-assign to Copilot.
+
+- Run running sanitizer only on cran branches to avoid pipeline contention.
+
