 - Added `-x`/`--exclude` flag for excluding file extensions (overrides `-e` or `-E` - `-E images -x jpg` scans all image

 - It is now possible to specify multiple extension sets at once: `-E images,system` will scan all images and archives
 - fif's output now includes the directory it was run from
+- Added `-q`/`--quiet` flag for reducing output verbosity
+#### Bugfixes
+- Resolved some discrepancies between `application/xml` and `text/xml`
 #### Other
 - Published my fork of ['mime_guess'] as ['new_mime_guess'], allowing it to be used properly with
   [crates.io](https://crates.io)
 - The `videos` extension set has been renamed to `video`, in line with `audio`. `fif --help` has actually mistakenly
   referred to the set as `video` since v0.2.12! 0uo
 - CI has been vastly improved

 ### Logging

+By default, fif will log any info, warnings, and errors encountered during execution. This can be changed with the `-v`
 flag:
 ```bash
-# also log info
+# also log debug info
 fif -v ~/Downloads
-# ...and debug
+# ...and trace info
 fif -vv ~/Downloads
-# ...and trace
-fif -vvv ~/Downloads
 ```
-The verbosity of the logging can be
-modified by the `RUST_LOG` to one of: `trace`, `debug`, `info`, `warn`, `error`.
+
+You can also reduce the level of logging with the `-q` flag:
+```bash
+# don't show info
+fif -q ~/Downloads
+# ...or warnings
+fif -qq ~/Downloads
+# ...or even errors!
+fif -qqq ~/Downloads
+```
+
+The verbosity of the logging can also be modified by setting the environment variable `RUST_LOG` to `off`, `trace`,
+`debug`, `info`, `warn`, or `error`. Values set by `RUST_LOG` override the `-v` and `-q` flags.
 
 For example:
 
 ```bash
+# show all levels except trace
 RUST_LOG=debug fif ~/Downloads
+# only show errors
+RUST_LOG=error fif ~/Downloads
 ```
 
 The five logging levels are used as follows:
