+- Add SECURITY.md
+
+- Add Dependabot configuration

+## Version 1.4 (released August 19, 2025)
 
 - Remove .gitattributes file (which was used to test different line endings, and
-caused issues in some build environments).

+- Strip trailing whitespace from Host declarations and key/value pairs.
 Previously, if a Host declaration or a value had trailing whitespace, that
 whitespace would have been included as part of the value. This led to unexpected
 consequences. For example:

+# ssh_config security policy
+
+## Supported Versions
+
+As of September 2025, we're not aware of any security problems with ssh_config,
+past or present. That said, we recommend always using the latest version of
+ssh_config, and of the Go programming language, to ensure you have the most
+recent security fixes.
+
+## Reporting a Vulnerability
+
+We take security vulnerabilities seriously. If you discover a security vulnerability in ssh_config, please report it responsibly by following these steps:
+
+### How to Report
+
+Please follow the instructions outlined here to report a vulnerability
+privately: https://docs.github.com/en/code-security/security-advisories/guidance-on-reporting-and-writing-information-about-vulnerabilities/privately-reporting-a-security-vulnerability
+
+If these are insufficient - it is not hard to find Kevin's contact information
+on the Internet.
+
+### What to Include
+
+When reporting a vulnerability, please include a clear description of the vulnerability, steps to reproduce the issue, the potential impact, as well as any fixes you might have.
+
+### Response Timeline
+
+I'll try to acknowledge and patch the issue as quickly as possible.
+
+Security advisories for this project will be published through:
+- GitHub Security Advisories on this repository
+- an Issue on this repository
+- The project's release notes
+- Go vulnerability databases
+
+If you are using `ssh_config` and would like to be on a "pre-release"
+distribution list for coordinating releases, please contact Kevin directly.
+
+### Security Considerations
+
+When using ssh_config, please be aware of these security considerations.
+
+#### File System Access
+
+This library reads SSH configuration files from the file system. Try to ensure
+proper file permissions on SSH config files (typically 600 or 644), and be
+cautious when parsing config files from untrusted sources.
+
+#### Input Validation
+
+The parser handles user-provided SSH configuration data. While we try our best
+to parse the data appropriately, malformed configuration files could potentially
+cause issues. Please try to validate and sanitize any configuration data from
+external sources.
+
+#### Dependencies
+
+This project does not have any third party dependencies. Please try to keep your
+Go version up to date.
+
+## Acknowledgments
+
+We appreciate security researchers and users who responsibly disclose vulnerabilities. Contributors who report valid security issues will be acknowledged in our security advisories (unless they prefer to remain anonymous).
