v0.1.13: Genoa

Changed

• Introduce sub-commands to the CLI. Now we have dedicated sub-commands for
  compile, doc, shell-completion and the language-server, which makes
  for a cleaner CLI.
  seanyoung
• On Solana, emitted events are encoded with Borsh encoding following the Anchor
  format.
  LucasSte
• The ewasm target has been removed, since ewasm is not going to implemented on
  Ethereum. The target has been reused for an new EVM target, which is not complete
  yet.
  seanyoung
• Substrate: Concrete contracts must now have at least one public function. A
  public function is in a contract, if it has public or external functions, if
  it has a receive or any fallback function or if it has public storage items
  (those will yield public getters). This aligns solang up with ink!.

Added

• Solana v1.11 is now supported.
  seanyoung
• On Solana, programs now use a custom heap implementation, just like on
  Substrate. As result, it is now possible to .push() and .pop() on
  dynamic arrays in memory.
  seanyoung
• Arithmetic overflow tests are implemented for all integer widths,
  salaheldinsoliman
• Add an NFT example for Solana
  LucasSte

• The selector for functions can be overriden with the selector=hex"abcd0123"
  syntax.
  seanyoung
• Shell completion is available using the solang shell-completion subcommand.
  xermicus
• Add support for the create_program_address() and try_find_program_address()
  system call on Solana
  seanyoung
• Substrate: The print() builtin is now supported and will write to the debug
  buffer. Additionally, error messages from the require statements will now be
  written to the debug buffer as well. The Substrate contracts pallet prints the
  contents of the debug buffer to the console for RPC ("dry-run") calls in case
  the runtime::contracts=debug log level is configured.
