+### Filter Response by Word Count & Line Count  (new in `v1.6.0`)
+
+In addition to filtering on the size of a response, version 1.6.0 added the ability to filter out responses based on the number of lines and/or words contained within the response body.  This change drove a change to the information displayed to the user as well. This section will detail the new information and how to make use of it with the new filters provided.
+
+Example output:
+```
+200        10l        212w       38437c https://example-site.com/index.html
+```
+
+There are five columns of output above:
+- column 1: status code - can be filtered with `-C|--filter-status`
+- column 2: number of lines - can be filtered with `-N|--filter-lines`
+- column 3: number of words - can be filtered with `-W|--filter-words`
+- column 4: number of bytes (overall size) - can be filtered with `-S|--filter-size`
+- column 5: url to discovered resource
+
+### Filter Response Using a Regular Expression (new in `v1.8.0`) 
+
+Version 1.3.0 included an overhaul to the filtering system which will allow for a wide array of filters to be added 
+with minimal effort. The latest addition is a Regular Expression Filter. As responses come back from the scanned server,
+the **body** of the response is checked against the filter's regular expression.  If the expression is found in the 
+body, then that response is filtered out.  
+
+**NOTE: Using regular expressions to filter large responses or many regular expressions may negatively impact performance.**  
+
+```
+./feroxbuster -u http://127.1 --filter-regex '[aA]ccess [dD]enied.?' --output results.txt --json
+```
+
+### Stop and Resume Scans (`--resume-from FILE`) (new in `v1.9.0`)
+
+Version 1.9.0 adds a few features that allow for completely stopping a scan, and resuming that same scan from a file on disk. 
+
+A simple `Ctrl+C` during a scan will create a file that contains information about the scan that was cancelled.
+
+![save-state](img/save-state.png)

+         }
+      }
+   ]
+},
+```
+
+Based on the example image above, the same scan can be resumed by using `feroxbuster --resume-from ferox-http_localhost-1606947491.state`.  Directories that were already complete are not rescanned, however partially complete scans are started from the beginning.  
+
+![resumed-scan](img/resumed-scan.gif)
+
+In order to prevent state file creation when `Ctrl+C` is pressed, you can simply add the entry below to your `ferox-config.toml`.
+
+```toml
+# ferox-config.toml
+
+save_state = false
+```
+
+### Enforce a Time Limit on Your Scan (new in `v1.10.0`)
+
+Version 1.10.0 adds the ability to set a maximum runtime, or time limit, on your scan.  The usage is pretty simple: a number followed directly by a single character representing seconds, minutes, hours, or days.  `feroxbuster` refers to this combination as a time_spec.  
+
+Examples of possible time_specs:
+- `30s` - 30 seconds
+- `20m` - 20 minutes
+- `1h`  - 1 hour
+- `1d`  - 1 day (why??)
+
+A valid time_spec can be passed to `--time-limit` in order to force a shutdown after the given time has elapsed.
