 # Changelog
 
+## [4.1.0] - 2022-02-07
+
+### Added
+
+-   `New` I added a new method, lib_path(), off the SASsession object which returns a list of the path(s) for
+the libref. Depending upon the engine, 'path' may mean different things. For BASE engines (Linux/PC), it's a directory
+or multiple directories if a concatenated libref. For database engines, it varies; may be the database name that you're
+connected to. On MVS, it could be then name of a bound library file, or a linux directory path.
+
+### Changed
+
+-   `Tweak` In the submit method of the HTTP access method, for results='text', I removed extraneous empty lines before
+and after the code. These resulted in extra 'return's being submitted. Removing these allows correct behavior when using
+saspy to interactively debug (w/ pdb) PROC PYTHON code. With the extra 'return' before and after the command you tried
+to submit, pdb executed extra commands. Now it's 1:1 with clean debugging using submit().
+
+### Fixed
+
+-   `None` No changes
+
+### Removed

+-   `None` Nothing removed

 ## [4.0.0] - 2022-01-14
 
 ### Added
 
 -   `Doc` I added this CHANGELOG.md to the repo to start tracking release changes in this file rather than just in the release notes.
 A changelog file seems to be a more conventional way to easily look through changes for each release. I'm not retroactively
-adding in the previous 59 versions worth of release notes to this, but will add all future releases.
