0.11.0

Changed

• Major improvement to report_package: Switched to a Revise.jl-based
  implementation that brings significant improvements (#763):

  • Incremental analysis: Analysis results are now cached and reused across
    multiple runs. When you analyze the same package again, only methods
    affected by code changes are re-analyzed, while unchanged methods reuse
    their cached results. This dramatically reduces analysis time for iterative
    development workflows.

    E.g. Incremental analysis on JET itself

    Screen.Recording.2025-10-23.at.03.01.14.mov

  • Improved robustness: The new implementation leverages Revise's
    battle-tested infrastructure for tracking package definitions, providing
    much more reliable analysis coverage across diverse code patterns compared
    to the previous custom code loading mechanism.

  • Breaking change: report_package now requires a Module argument
    instead of accepting a package name as AbstractString. Users must now
    load the target package before analysis. See the deprecated section for
    more details.

  • Limitation: As a trade-off of the Revise-based approach, report_package
    can no longer analyze packages that fail to load. Previously, report_package
    could atl least report top-level errors for such packages (though it
    couldn't perform inference-based analysis). Now users must fix loading
    errors before applying JET analysis via report_package. These errors are
    typically straightforward to fix by examining the error output from
    using MyPkg or Pkg.precompile().

  • The previous default configurations analyze_from_definitions=true and
    concretization_patterns=[:(x_)] are no longer needed or used, as the
    Revise-based approach does not require JET's own code loading mechanism.
    These configurations can still be used in other top-level analysis entry
    points (e.g. report_file and report_text).

• Revise.jl is now a required dependency instead of an optional weak
  dependency. This means watch_file no longer requires manually loading
  Revise with using Revise before use.
• Enabled the ad-hoc concrete evaluation
  in JETAnalyzer for Julia v1.13 and higher, reducing false positives in more general cases
• Module filtering behavior change: target_modules and ignored_modules
  now include submodules by default (#628, #772):
  • Submodule-inclusive filtering: When a Module object is passed to
    target_modules or ignored_modules, JET now matches not only that exact
    module but also all of its submodules. This provides more intuitive
    filtering behavior in most use cases.
  • Breaking change: This changes the filtering behavior when
    target_modules or ignored_modules accept an iterator of modules.
    To preserve the previous exact-match behavior (matching only the specified
    module without its submodules), wrap the module with LastFrameModuleExact
    or AnyFrameModuleExact:

    # New default (v0.11+): matches MyPackage and all its submodules
    report_call(f, args...; target_modules=(MyPackage,))
    
    # Previous behavior (v0.10): matched only MyPackage exactly
    # To preserve this in v0.11+, use:
    report_call(f, args...; target_modules=(LastFrameModuleExact(MyPackage),))

  • New matcher types:
    • ReportMatcher: abstract interface type for JET.match_report
    • LastFrameModuleExact: exact match in last frame only
    • AnyFrameModuleExact: exact match in any frame

Added

• Symbol-based module filtering: target_modules and ignored_modules now
  accept Symbol in addition to Module objects (#602, #773).
  This allows filtering by module name without requiring the module as a dependency:

  # Filter by module name without loading CUDA package
  report_call(f, args...; ignored_modules=(:CUDA,))
  
  # Equivalent to passing the Module object (if CUDA is loaded)
  report_call(f, args...; ignored_modules=(CUDA,))

  All matcher types (LastFrameModule, AnyFrameModule, LastFrameModuleExact,
  AnyFrameModuleExact) now accept Union{Module,Symbol}.

Deprecated

• report_package(::AbstractString), report_package([::Nothing]):
  The old signatures accepting a package name as a string, or no arguments are
  deprecated. Load the package first and pass the Module instead:

  # Preferred (v0.11):
  julia> using MyPackage
  julia> report_package(MyPackage)
  
  # Deprecated (v0.10):
  julia> report_package("MyPackage")
  julia> report_package()

• target_defined_modules configuration: Use the more flexible target_modules
  configuration instead. To limit error reports to your package's module
  context (filtering out errors from dependencies), use:

  report_package(MyPackage; target_modules=(MyPackage,))
