**`v0.35.0`** is there.

This is mostly a polish/small bug fix release. Also, monadic pipes are landed.

Was:

```elixir
  ## Move amount from available balance into hold
  fn reserve(ledger: Ledger, id: Int, amount: Exchange.Money.Money) -> Result(Ledger, String) =
    match find_account(ledger.accounts, id)
      Error(e) -> ledger_error(e)
      Ok(account) ->
        match Exchange.Money.subtract(account.balance, amount)
          Error(e) -> ledger_error(e)
          Ok(new_balance) ->
            match Exchange.Money.add(account.held, amount)
              Error(e) -> ledger_error(e)
              Ok(new_held) ->
                ledger_ok(update_account(ledger, Account{account | balance: new_balance, held: new_held}))

```

Now:

```elixir
  ## Move amount from available balance into hold
  fn reserve(ledger: Ledger, id: Int, amount: Exchange.Money.Money) -> Result(Ledger, String) =
    find_account(ledger.accounts, id)
    |account|> Exchange.Money.subtract(account.balance, amount)
    |new_balance|> Exchange.Money.add(account.held, amount)
    |new_held|> update_account(ledger, Account{account | balance: new_balance, held: new_held})

```
