# User visible changes in `mruby3.2`
# 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 `[]`).
- [#5870](https://github.com/mruby/mruby/issues/5870) Use OP_LOADINEG instead of OP_LOADI
# Tools
# Changes in mrbgems
## `mruby`
- mruby-bin-config: new options --cxx,--cxxflags,--as,--asflags,--objc,--objcflags
- mruby-binding-eval (merged with mruby-eval) #5989
- mruby-binding: renamed from mruby-binding-core
- mruby-enumerator: remove internal attribute methods obj, args, kwd, meth, fib.
- mruby-fiber: Add a new mrb_fiber_new() with MRB_API
- mruby-fiber: Allows calling `Fiber#resume` from C
- mruby-fiber: `Fiber#to_s` format changed
- mruby-io: Add "x" mode option for IO.open
- mruby-method: `Method#to_s` format changed
- mruby-pack: support new directives j,J,b,B
- mruby-range-ext: new method `Range#overlap?`
- 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`.
