fix(events): order events consistently when querying

CHANGELOG.md

@@ -17,8 +17,8 @@
 - Event APIs (Eth events and actor events) should only return reverted events if client queries by specific block hash / tipset. Eth and actor event subscription APIs should always return reverted events to enable accurate observation of real-time changes. ([filecoin-project/lotus#12585](https://github.com/filecoin-project/lotus/pull/12585))
 - Add logic to check if the miner's owner address is delegated (f4 address). If it is delegated, the `lotus-shed sectors termination-estimate` command now sends the termination state call using the worker ID. This fix resolves the issue where termination-estimate did not function correctly for miners with delegated owner addresses. ([filecoin-project/lotus#12569](https://github.com/filecoin-project/lotus/pull/12569))
 - Fix a bug in F3 participation API where valid leases may get removed due to dynamic manifest update. ([filecoin-project/lotus#12597](https://github.com/filecoin-project/lotus/pull/12597))
-
 - Change the F3 participation ticket encoding to allow parity testing across non-go implementations, where a ticket issued by Lotus may need to be decoded by, for example, Forest . The changes also enforce the minimum instance participation of 1 for miners. ([filecoin-project/lotus#12615](https://github.com/filecoin-project/lotus/pull/12615))
+- Make the ordering of event output for `eth_` APIs and `GetActorEventsRaw` consistent, sorting ascending on: epoch, message index, event index and original event entry order. ([filecoin-project/lotus#12623](https://github.com/filecoin-project/lotus/pull/12623))
