-## Unreleased
+## v0.2.0.0 Berlin
+We are happy to release solang `v0.2.0` codenamed `Berlin` today. Aside from containing many small fixes and improvements, this release marks a milestone towards maturing our Substrate compilation target: any regressions building up since `ink!` v3.0 are fixed, most notably the metadata format (shoutout and many thanks to external contributor [extraymond](https://github.com/extraymond)) and event topics. Furthermore, we are leaving `ink!` version 3 behind us, in favor of introducing compatibility with the recent `ink!` 4 beta release and the latest pallet contract `v0.22.1`.
 
 ### Added
-- Introduce new sub-command `solang idl` which can be used for generating
+- **Solana / breaking:** The try-catch construct is no longer permitted on Solana, as it
+   never worked. Any CPI error will abort the transaction.
+   [seanyoung](https://github.com/seanyoung)
+- **Solana:** Introduce new sub-command `solang idl` which can be used for generating
   a Solidity interface file from an Anchor IDL file. This can be used for calling
   Anchor Contracts on Solana. [seanyoung](https://github.com/seanyoung)
+- **Substrate:** Provide specific Substrate builtins via a "substrate" file. The
+  `Hash` type from `ink!` is the first `ink!` specific type made available for Solidity
+  contracts.
+  [xermicus](https://github.com/xermicus)
+- **Substrate:** Introduce the `--log-api-return-codes` CLI flag, which changes the
+  emitted code to print return codes for `seal` API calls into the debug buffer.
+  [xermicus](https://github.com/xermicus)
+- Introduce function name mangling for overloaded functions and constructors, so
+  that they can be represented properly in the metadata.
+  [xermicus](https://github.com/xermicus)
+
+### Changed
+ - The Solana target now uses Borsh encoding rather than eth abi
+   encoding. This is aimed at making Solang contracts Anchor compatible.
+   [LucasSte](https://github.com/LucasSte)
+- **Substrate / breaking:** Supported node version is now pallet contracts `v0.22.1`.
+  [xermicus](https://github.com/xermicus)
+- **Substrate / breaking:** Remove the deprecated `random` builtin.
+  [xermicus](https://github.com/xermicus)
+
+### Fixed
+ - Whenever possible, the parser does not give up after the first error.
+   [salaheldinsoliman](https://github.com/salaheldinsoliman)
+ - Constant expressions are checked for overflow.
+   [salaheldinsoliman](https://github.com/salaheldinsoliman)
+ - AddMod and MulMod were broken. This is now fixed.
+   [LucasSte](https://github.com/LucasSte)
+- **Substrate / breaking:** Solang is now compatible with `ink!` version 4 (beta).
+  [xermicus](https://github.com/xermicus)
+- **Substrate:** Switched ABI generation to use official `ink!` crates, which fixes all
+  remaining metadata regressions.
+  [extraymond](https://github.com/extraymond) and [xermicus](https://github.com/xermicus)
+- **Substrate:** Allow constructors to have a name, so that multiple constructors are 
+  supported, like in `ink!`.
+  [xermicus](https://github.com/xermicus)
+- All provided examples as well as most of the Solidity code snippets in our
+  documentation are now checked for succesful compilation on the Solang CI.
+  [xermicus](https://github.com/xermicus)
+- **Substrate:** Fix events with topics. The topic hashes generated by Solang
+  contracts are now exactly the same as those generated by `ink!`.

 ## Build for Substrate
 
-### Status
-:warning: Solang was developed against Substrate v3.0. It has been a while since the last time the Substrate target was worked on, which introduced a few known regressions. Currently, the following is known to **not** work with recent Substrate versions:
-
-* Function call arguments of type `address`
-* Function return values of type `address`
-* Cross-contract calls
-* Events with indexed fields
-
-Maintenance on the Substrate target has now resumed and we are working on fixing these issues.
