+# User visible changes in `mruby3.3` from `mruby3.2`
 
 # The language
 
-- Now `a::B = c` should evaluate `a` then `c`.
-- Anonymous arguments `*`, `**`, `&` can be passed for forwarding.
-- Multi-precision integer is available now via `mruby-bigint` gem.
+- aliases work properly with `super`
+- `callee` method work differently with aliases in mruby
+- define `Kernel#respond_to_missing?` method
+- `_inspect` method (`inspect` with recursive check) is removed
+- `__printstr` method is removed; use `print` instead
+
+# Configuration
+
+- mruby can be built using Docker now. Try `docker-compose build` for example.
+- New Platform: Nintendo Wii
+- Improved Platforms: Android, Dreamcast
+
+# mruby memory API
+
+- `mrb_default_allocf` can be overridden by the application
+- `mrb_open_allocf` will be deprecated
 
 # mruby VM and bytecode
 
-- `OP_ARYDUP` was renamed to `OP_ARYSPLAT`. The instruction name
-  was changed but instruction number and basic behavior have not
-  changed (except that `ARYDUP nil` makes `[]`).

+- mruby-string-ext: Add `String#valid_encoding?` method
 
-- `-b` only specifies the script is the binary. The files loaded by `-r` are not affected by the option.
-- `mruby` now loads complied binary if the suffix is `.mrb`.
