Added

• Added support for Wasm custom sections processing. (#1085)
  • It is now possible to query name and data of Wasm custom sections of a Module.
  • Use the new Config::ignore_custom_sections flag to disable this functionality.
• Added Config::ignore_custom_sections flag to disable processing custom sections if this is unwanted. (#1085)
• Add Memory::{data_ptr, data_size, size} methods. (#1082)
• Added a Wasmi usage guide documentation. (#1072)
  • Link: https://github.com/wasmi-labs/wasmi/blob/master/docs/usage.md

Changed

• Optimized the Wasmi executor in various ways.
  • In summary the Wasmi executor now more optimally caches the currently used
    Wasm instance and optimizes access to instance related data.
    In particular access to the default linear memory bytes as well as the global
    variable at index 0 (often used as shadow stack pointer) are more efficient.
  • The following PRs are part of this effort:
    • #1059
    • #1062
    • #1068
    • #1069
    • #1065
    • #1075
    • #1076
• Changed Memory::grow signature to mirror Wasmtime's Memory::grow method. (#1082)

Removed

• Removed Memory::current_pages method. (#1082)
  • Users should use the new Memory::size method instead.
