feat: add future time shift strings (#2048)

CHANGELOG.md

@@ -17,6 +17,12 @@ Changes are grouped as follows
 - `Fixed` for any bug fixes.
 - `Security` in case of vulnerabilities.
 
+## [7.69.3] - 2024-12-02
+### Added
+- API endpoints currently accepting relative time strings like `2d-ago` now support a forward-looking syntax, e.g. `2w-ahead` or `15m-ahead`.
+### Fixed
+- Revoking sessions through `client.iam.sessions.revoke` no longer raises an API error for very large payloads
+
 ## [7.69.2] - 2024-11-28
 ### Improved
 - Handle conversion of instance lists like NodeList to pandas DataFrame in scenarios where: a) properties are expanded
