+=== Implementation improvements
+
+* Optimize Proc#call to eliminate method frame construction.
+ [Feature #11569]
+
+* Reconsidering method entry data structure.
+ [Bug #11278]
+
+* Introducing new table data structure for ID keys tables used by
+ method table and so on. New table structure is simple and fast
+ than st_table. [Feature #11420]
+
+* Machine code level tuning for object allocation and method calling
+ code. r52099, r52254
+
+* RubyVM::InstructionSequence is extended for future improvement.
+ [Feature #11788]
+
+* Case dispatch is now optimized for all special constant literals
+ including nil, true, and false. Previously, only literal strings,
+ symbols, integers and floats compiled to optimized case dispatch.
+ [Feature #11769]
+
+* Instance variables on non-pure Ruby classes (T_DATA, T_FILE,
+ etc..) is less expensive to store than before. [Feature #11170]
+
+* All accesses to members of big Struct objects are performed in
+ constant-time. Previously, Struct elements beyond the first 10
+ 10 elements used a linear scan. [Feature #10585]
+
+* The Set class got several speedps.
+ [Misc #10754], [r52591]
+
+* Socket and I/O related improvements
+
+ * All non-blocking I/O (including socket) methods allow
+ `exception: false' to suppress expensive and noisy exceptions
+ in common usage. Feature #10532 [Feature #11229]
+
+ * Calling overhead of most of these keyword-using I/O methods is
+ reduced by avoiding the inefficient C API to parse keywords.
+ [Feature #11339]
+
+ * The standard library is updated to use the improved
+ exception-free non-blocking I/O. This has the additional
+ benefit of quieter $DEBUG output in addition to reducing expensive
+ exceptions. [Feature #11044]
+
+ * The Socket#recv* methods allow an optional destination
+ buffer to reduce GC pressure, based on the existing behavior
+ of IO#read* methods. [Feature #11242]
+
+ * (Linux-only) waiting on a single FD anywhere in the stdlib no longer
+ uses select(2), making it immune to slowdowns with high-numbered FDs.
