+Change log v.0.10.9
+
+**Minor**: minor update to the cache system, might improve performance somewhat and might fix rare issues related to some binary files. Updated GRHttp server version required.
+
+**Fix**: fixed an issue with Placebo listeners where they might be thrown from the IO stack and thereby stop listening ()or, alternatively, consume CPU) . This issue was caused by GReactor's 'BasicIO#clear?' code enforcing two-way connectivity.
