  • BUGFIX: teams: fixed multiple issues when merging types

  • BUGFIX: teams: hvui: in Local files and Vault files the first line could be empty after opening

  • BUGFIX: UI: correcly retrieve library name for custom signatures files

  • BUGFIX: UI: fixed several cases where IDA would open the deprecated Structures view instead of Local Types
