 jc changelog
 
+20210830 v1.16.2
+- Note to Package Maintainers: please see note at 20210720 v1.16.0
+- Update sfdisk parser to support the -F option and newer versions of sfdisk
+
+20210813 v1.16.1
+- Note to Package Maintainers: please see note at 20210720 v1.16.0
+- Fix issue with process substitution with the magic syntax
+- Fix issue with globs not including filenames with spaces with magic syntax
+- Fix stat parser to properly handle filenames with spaces on macOS/BSD
+
+20210720 v1.16.0
+- Note to Package Maintainers:
+    TL;DR: `/man/jc.1.gz` and `/jc/man/jc.1.gz` are deprecated and only `/man/jc.1` should be used.
+    
+    The Man page in the PyPi source packages will be moving from `/jc/man/jc.1.gz` to `/man/jc.1`
+    in version 1.17.0. For now the Man pages will be available in both locations, but be aware that
+    the Man page at `/jc/man/jc.1.gz` is now considered deprecated.
+
+    Also, starting in v1.17.0, the Man page will no longer be compressed in the source package,
+    therefore `/man/jc.1.gz` should also be considered deprecated and will no longer be available
+    after v1.17.0. Please use `/man/jc.1` and compress downstream if you would like.
+- Include CHANGELOG in source distribution
+- Fix Man page location in source packages
+- Add sfdisk command parser tested on linux
+- Update unit test files to change the timezone when needed (POSIX only)
+- Binaries and DEB/RPM/MSI packages now include Python 3.9.5 interpreter
+
+20210628 v1.15.6
+- Fix issue to only load local plugin parsers that have filenames that end in .py 
+
+20210520 v1.15.5
+- Fix issue where help and about information would not display if a 3rd party parser library was missing. (e.g. xmltodict)
+- Add more error message detail when encountering ParseError and LibraryNotFound exceptions
+
+20210517 v1.15.4
+- Update ping parser to support error responses in OSX and BSD
+- Update ping parser to be more resilient against parsing errors for unknown error types
+- Update dig parser to support `+noall +answer` use case
+- Update dig parser compatibility to all platforms
+- Fix colors in Windows terminals (cmd.exe and PowerShell)
+- Fix epoch calculations when UTC is referenced as "Coordinated Universal Time"
+- Add Windows time format for systeminfo output
+- Add exceptions module to standardize parser exceptions
+- JC no longer swallows exit codes when using the "magic" syntax. See the Exit Codes section of the README and man page for details
+
+20210426 v1.15.3
+- Add ufw status command parser tested on linux
+- Add ufw-appinfo command parser tested on linux
+- Fix deb package name to conform to standard
+- Add Caveats section to readme and manpage

 1. Open an issue to discuss the new feature, bug fix, or parser before opening a pull request. For new parsers, it is important to agree upon a schema before developing the parser.
 2. Fork the repo and create your branch from `dev`, if available, otherwise `master`.
-3. If you've added code that should be tested, add tests. All new parsers should have several sample outputs and tests.
-4. Documentation is auto-generated from docstrings, so ensure they are clear and accurate.

+3. For new parsers: Use the `jc/parsers/foo.py` parser as a [template](https://github.com/kellyjonbrazil/jc/blob/master/jc/parsers/foo.py) to get started. You can even place a new parser python module file in the [parser plugin directory](https://github.com/kellyjonbrazil/jc#custom-parsers) to get started right away with just a standard `jc` installation.

+## Tests
+It is essential to have good command output sample coverage and tests to keep the `jc` parser quality high.
+
+Many parsers include calculated timestamp fields using the `jc.utils.timestamp` class. Naive timestamps created with this class should be generated on a system configured with the "**America/Los_Angeles**" timezone on linux/macOS/unix and "**Pacific Standard Time**" timezone on Windows for tests to pass on the Github Actions CI tests. This timezone should be configured on your local system before running the tests locally, as well.

+### Exit Codes
+Any fatal errors within `jc` will generate an exit code of `100`, otherwise the exit code will be `0`. When using the "magic" syntax (e.g. `jc ifconfig eth0`), `jc` will store the exit code of the program being parsed and add it to the `jc` exit code. This way it is easier to determine if an error was from the parsed program or `jc`.

+**Locale:**
+
+For best results set the `LANG` locale environment variable to `C` or `en_US.UTF-8`. For example, either by setting directly on the command-line:

+**Timezones:**

+Some parsers have calculated epoch timestamp fields added to the output. Unless a timestamp field name has a `_utc` suffix it is considered naive. (i.e. based on the local timezone of the system the `jc` parser was run on).

+If a UTC timezone can be detected in the text of the command output, the timestamp will be timezone aware and have a `_utc` suffix on the key name. (e.g. `epoch_utc`) No other timezones are supported for aware timestamps.

 ## Compatibility

 # jc.parsers.dig
 jc - JSON CLI output utility `dig` command output parser
 
+Options supported:
+- `+noall +answer` options are supported in cases where only the answer information is desired.
+- `+axfr` option is supported on its own
+
 The `when_epoch` calculated timestamp field is naive (i.e. based on the local time of the system the parser is run on)
 
 The `when_epoch_utc` calculated timestamp field is timezone-aware and is only available if the timezone field is UTC.

-- `-h`: File sizes will be available in text form with `-r` but larger file sizes with human readable suffixes will be converted to `Null` in the default view since the parser attempts to convert this field to an integer.
 
 Note: The `-1`, `-l`, or `-b` option of `ls` should be used to correctly parse filenames that include newline characters. Since `ls` does not encode newlines in filenames when outputting to a pipe it will cause `jc` to see multiple files instead of a single file if `-1`, `-l`, or `-b` is not used. Alternatively, `vdir` can be used, which is the same as running `ls -lb`.

+# jc.parsers.systeminfo
+jc - JSON CLI output utility `systeminfo` command output parser
+
+Blank or missing elements are set to `null`.
+
+The `original_install_date_epoch` and `system_boot_time_epoch` calculated timestamp fields are naive (i.e. based on the local time of the system the parser is run on)
+
+The `original_install_date_epoch_utc` and `system_boot_time_epoch_utc` calculated timestamp fields are timezone-aware and are only available if the timezone field is UTC.
+
+Usage (cli):
+
+    $ systeminfo | jc --systeminfo
+
+Usage (module):
+
+    import jc.parsers.systeminfo
+    result = jc.parsers.systeminfo.parse(systeminfo_command_output)

+# jc.parsers.ufw_appinfo
+jc - JSON CLI output utility `ufw app info [application]` command output parser
+
+Supports individual apps via `ufw app info [application]` and all apps list via `ufw app info all`.
+
+Because `ufw` application definitions allow overlapping ports and port ranges, this parser preserves that behavior, but also provides `normalized` lists and ranges that remove duplicate ports and merge overlapping ranges.
+
+Usage (cli):

 Options supported:
 - `lbaR1`
 - `--time-style=full-iso`
-- `-h`: File sizes will be available in text form with `-r` but larger file sizes with human readable suffixes will be converted to `Null` in the default view since the parser attempts to convert this field to an integer.
 
 Note: The `-1`, `-l`, or `-b` option of `ls` should be used to correctly parse filenames that include newline characters. Since `ls` does not encode newlines in filenames when outputting to a pipe it will cause `jc` to see multiple files instead of a single file if `-1`, `-l`, or `-b` is not used. Alternatively, `vdir` can be used, which is the same as running `ls -lb`.
