 # CHANGELOG
 
+## 1.4.8 (future release)
+
+  - New constructor for BinaryHttpResponseHandler which takes Looper as argument (thanks to @ScottFrank)
+  - SaxAsyncHttpResponseHandler can be now provided with custom charset, instead of just using default one
+  - Library LogCat tags now use shorter form (forced through Lint checks), appendix "ResponseHandler" shortened to "RH"
+  - Updated documentation on `RequestHandle.cancel(boolean)` and returning correct response according to handle state
+  - SaxAsyncHttpResponseHandler onFailure(int, Header[], byte[], Throwable) used wrong fallback to onSuccess(int, Header[], T), fixed to onFailure(int, Header[], T), where T extends SAX DefaultHandler
+  - Regression fix on onProgress(int,int) documentation
+  - Sample application now can be built with LeakCanary, use i.e. `gradle :sample:installWithLeakCanaryDebug` to use it
+  - Updated RequestParams documentation on handling arrays, sets and maps, along with new RequestParamsDebug sample
+
