# Python SDK 17.3.0

* **KSM-992:** Added typed `KeeperRecordLink` linked-credential accessors. `record.get_links()` returns typed link objects exposing user and permission flags, encryption detection, AES-256-GCM decryption, and `meta`/`ai_settings`/`jit_settings` settings access, matching the Java SDK's `KeeperRecordLink` API. Purely additive: the raw `record.links` list is unchanged.
* **KSM-877:** Added automatic throttle retry with exponential backoff. HTTP 403 throttle responses are retried up to 5 times (11s, 22s, 44s, 88s, 176 s ±25% jitter); `retry_after` in the response is honored. Raises `KeeperThrottleError` once retries are exhausted. No caller changes required.
* **KSM-932:** Added custom server public key support for isolated deployments; key can be supplied programmatically via `SecretsManager` parameters, embedded in the one-time token (4-segment format), or set in the config file before the first call.
* **KSM-807:** Fixed partial config file left behind after a failed initialization (expired or already-consumed One-Time Token). The SDK now automatically removes the incomplete file on failure and raises a clear error instructing the user to generate a fresh token.
* **KSM-808:** Missing config keys now raise `KeeperError` naming the specific missing field instead of a cryptic `TypeError`.
* **KSM-813:** Fixed Windows ACL sequence in `set_config_mode()` to fully remove Everyone read access from config files (previously only Full Control was removed).
* **KSM-819:** Fixed `RecordCreate.to_dict()` silently dropping `"custom": []` when no custom fields are set. Records now correctly include the empty list, matching Commander and Vault behavior.
* **KSM-1004:** `KSMCache` now resolves the cache path from `KSM_CACHE_DIR` at call time, so the environment variable is honored even when set after import. Default behavior is unchanged.

**Helper Package:**

* **1.1.2:** Bumped to require `keeper-secrets-manager-core>=17.3.0`

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.keeper.io/release-notes/enterprise/keeper-secrets-manager/2026/python-sdk-17.3.0.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
