    • Improve package name validation during the new project creation

  • Suggest the run configuration name from its command
  • Allow folding of consecutive impl Iterator<Item=X>s in a method chain hints (by @Kobzol)
  • Code coverage integration improvements:
    • Allow using any nightly toolchain to run code with coverage

  • Update Cargo-related icons

Performance Improvements

  • Don’t annotate user-defined attribute macros that override built-in ones (by @Stzx)
