Thanks @klauer 

Version 4.1.0

This new version contains big quality of life improvements.

Highlights

Documentation: We now have readthedocs documentation that covers usage tutorials and the API.

Explicit Decorator: There is now a global profile decorator. In your code import line_profiler and decorate functions with @line_profiler.profile. Your code runs as normal by default. Setting the environment variable LINE_PROFILE=1 will enable profiling. For details see the docs.

Auto-Profiling: Users can now run kernprof with -p <modname> to profile all functions in a module without explicitly decorating them. For details see the docs.

CHANGELOG

• FIX: skipzeros now checks for zero hits instead of zero time
• FIX: Fixed errors in Python 3.11 with duplicate functions.
• FIX: show_text now increases column sizes or switches to scientific notation to maintain alignment
• ENH: show_text now has new options: sort and summarize
• ENH: Added new CLI arguments -srm to line_profiler to control sorting, rich printing, and summary printing.
• ENH: New global profile function that can be enabled by --profile or LINE_PROFILE=1.
• ENH: New auto-profile feature in kernprof that will profile all functions in specified modules.
• ENH: Kernprof now outputs instructions on how to view results.
• ENH: Added readthedocs integration: https://kernprof.readthedocs.io/en/latest/index.html

Version 4.0.3

4.0.3

* FIX: Stop requiring bleeding-edge Cython unless necesasry (for Python 3.12).  #206

Version 4.0.2

• FIX: AttributeError on certain methods. #191

Version 4.0.1

• FIX: Profiling classmethods works again. #183

Version 4.0.0

• ENH: Python 3.11 is now supported.
• ENH: Profiling overhead is now drastically smaller, thanks to reimplementing almost all of the tracing callback in C++. You can expect to see reductions of between 0.3 and 1 microseconds per line hit, resulting in a speedup of up to 4x for codebases with many lines of Python that only do a little work per line.
• ENH: Added the -i <# of seconds> option to the kernprof script. This uses the threading module to output profiling data to the output file every n seconds, and is useful for long-running tasks that shouldn't be stopped in the middle of processing.
• CHANGE: Cython's native cythonize function is now used to compile the project, instead of scikit-build's convoluted process.
• CHANGE: Due to optimizations done while reimplementing the callback in C++, the profiler's code_map and last_time attributes now are indexed by a hash of the code block's bytecode and its line number. Any code that directly reads (and processes) or edits the code_map and/or last_time attributes will likely break.

Thanks to @Theelx and others for all of their hard work on this!
