Summary

Steep 2.0 introduces three major new features.

• Inline RBS Declaration (Experimental): Files configured with check(inline: true) can now have RBS type declarations written directly in Ruby code. Supports method types, attr_*, instance variables, constants, mixins, inheritance, and more, with editor integration for completion, hover, and go-to-definition.
• steep server command: A daemon server that persists the RBS environment. By connecting to the daemon during steep check, it skips RBS environment setup and speeds up type checking.
• steep query command: Query type information from the daemon server. steep query hover retrieves hover information and steep query definition retrieves definition locations, making type information accessible outside of editors.

In addition, this release includes many improvements such as type narrowing for block_given?, type checking arbitrary expressions with the steep check with -e option, and Prism parser introduction for Ruby 3.4+.
