# Version 3.0 (2020-10-09)

# Version 3.0-rc2 (2020-10-22)
2+
3+
This is the 2nd release candidate for ink! 3.0.
4+
5+
On top of the changes introduced in the first release candidate for ink! 3.0 we introduced
6+
the following improvements, new features and bug fixes:
7+
8+
- The `ink_storage` crate now comes with a new `BinaryHeap` data structure
9+
that has a very similar interface to the well known Rust standard library
10+
`BinaryHeap`. It features specific optimizations to reduce the storage reads
11+
and writes required for its operations.
12+
- Fixed a bug with `ink_storage::Lazy` that corrupted the storage of
13+
other storage data structures if it was unused in a contract execution.
14+
- The `ink_storage::alloc::Box` type now implements `scale_info::TypeInfo` which
15+
now allows it to be fully used inside other storage data structures such as
16+
`ink_storage::collections::Vec`. The missing of this implementation was
17+
considered a bug.
18+
- The `LazyHashMap` low-level storage abstraction is now re-exported from within
19+
the `ink_storage::lazy` module and docs are inlined.
20+
- Added note about the `ink_core` split into `ink_env` and `ink_storage` crates
21+
to the release notes of ink! 3.0-rc1.
22+
- The `Cargo.toml` documentation now properly links to the one deployed at docs.rs.
23+
On top of that crate level documentation for the `ink_allocator` crate has been
24+
added.
25+
- Add new ERC-20 example contract based on a trait implementation. Also modernized
26+
the old non-trait based ERC-20 example token contract.
27+

# Version 3.0-rc1 (2020-10-09)

Be prepared for the ink! 3.0 release notes because the whole version was basically a rewrite of
431
all the major components that make up ink!. With our experience gained from previous releases
