 - chore: update maintainer guidelines link in MAINTAINERS.md (#1605)
 - chore: update merge conflict bot message with web editor tips (#1592)
 - chore: update MAINTAINERS.md to include new maintainer Manish Dait and sort maintainers by GitHub ID. (#1691)
+- Changed `TransactionResponse.get_receipt()` so now pins receipt queries to the submitting node via `set_node_account_ids()` ([#1686](https://github.com/hiero-ledger/hiero-sdk-python/issues/1686))
 - chore: clarify wording in the bot-assignment-check.sh (#1748)
 - Refactored SDK dependencies to use version ranges, moved build-only deps out of runtime, removed unused core deps and added optional extras.
 
-
 ### Fixed
 - Corrected broken documentation links in SDK developer training files.(#1707)
 - Fixed assignment limit check to only count issues (not PRs) towards the maximum 2 concurrent assignments, allowing users to be assigned to PRs without affecting their issue assignment capacity. (#1717)
