* Add rust 1.74.0 to the test matrix

* Add rust 1.74.0 to the test matrix

* Correct some mistakes in README.md about older macos versions.

* Debug builds

* Rollback changes and disable some lints

* Bump version for next release fixing lints issues

* Add rustc version output to before clippy

* Localize the allows

* Allow all on those lines

+The minimum rust version required is currently: 1.74.1 and this is tested in CI and must pass.

+# Test Matrix
+The Github Actions CI matrix is:
 
-## Mac OS X Versions
-Calls were aded to libproc in Mac OS X 10.7 and again in 10.9. 
-This library can be compiled to not include those calls by using rust `features`
-to enable/disable support for those versions.

+* `beta` (must pass)
+* `1.74.1` (currently the minimum rust version supported) (must pass)

-The default build is for Mac OS 10.9 or later. See:

-To build for versions prior to Mac OS 10.7 disable the default features by passing --no-default-features to cargo.
 
-To build for Mac OS X 10.7 (or 10.8) you can enable that feature alone using
---no-default-features --features "macosx_10_7"
+## Mac OS X Versions
+Calls were added to libproc in 10.9 (Mavericks) and they are under a rust "feature" switch called "macosx_10_9".
+The default build includes the "macosx_10_9" feature.
