+## 1.13.0
+### Added
+- Added --dry-run option to subscriber and downloader to view the files that _would_ be downloaded without actuall downloading them. [102](https://github.com/podaac/data-subscriber/issues/102)
+- Added new feature allowing regex to be used in `--extension` `-e` options. For example using -e `PTM_\\d+` would match data files like `filename.PTM_1`, `filename.PTM_2` and `filename.PTM_10`, instead of specifying all possible combinations (`-e PTM_1, -e PTM_2, ..., -e PMT_10`) [115](https://github.com/podaac/data-subscriber/issues/115)
+- Added check for updated version [70](https://github.com/podaac/data-subscriber/issues/70)
+- Removed CMR Token from log messages [127](https://github.com/podaac/data-subscriber/issues/127)

+Some collections have many files. To download a specific set of files, you can set the extensions on which downloads are filtered. By default, ".nc", ".h5", and ".zip" files are downloaded by default. The `-e` option is a regular expression check so you can do advanced things like `-e PTM_\\d+` to match `PTM_` followed by one or more digits- useful when the ending of a file has no suffix and has a number (1-12 for PTM, in this example)

 ### run a post download process
 
 Using the `--process` option, you can run a simple command agaisnt the "just" downloaded file. This will take the format of "<command> <path/to/file>". This means you can run a command like `--process gzip` to gzip all downloaded files. We do not support more advanced processes at this time (piping, running a process on a directory, etc).

+### OTHER OPTIONS
+
+The podaac downloader and subscriber make calls to github for checking recent releases. Unauthenticated requests are limited to 60 per hour. If you start seeing errors like:
+```
+releases_json = {'documentation_url': 'https://docs.github.com/rest/overview/resources-in-the-rest-api#rate-limiting', 'message': "API... here's the good news: Authenticated requests get a higher rate limit. Check out the documentation for more details.)"}
+```
+You'll want to set the environment variable GITHUB_TOKEN to a github personal access token- this allows for up to 5000 calls per hour. This requires a free github account. Most users will not run in to this issue.
