 Please also refer to the Changelog of Element Android: https://github.com/vector-im/element-android/blob/main/CHANGES.md
 
+Changes in Matrix-SDK 1.3.18 (2022-02-04)
+===================================================
+
+**Warning**: This release may trigger an initial sync.
+
+Imported from Element 1.3.18. (https://github.com/vector-im/element-android/releases/tag/v1.3.18)
+
+Bugfixes 🐛
+----------
+ - Avoid deleting root event of CurrentState on gappy sync. In order to restore lost Events an initial sync may be triggered. ([#5137](https://github.com/vector-im/element-android/issues/5137))
+
+SDK API changes ⚠️
+------------------
+ - `StateService.sendStateEvent()` now takes a non-nullable String for the parameter `stateKey`. If null was used, just now use an empty string. ([#4895](https://github.com/vector-im/element-android/issues/4895))
+ - 429 are not automatically retried anymore in case of too long retry delay ([#4995](https://github.com/vector-im/element-android/issues/4995))
+
+

+     * Until now we use unsignedData.transactionId to determine whether or not the local

+     * at the following scenario:
+     *
+     * [There is no Internet connection] --> [10 Messages are sent] --> [The 10 messages are in the queue] -->
+     * [Internet comes back for 1 second] --> [3 messages are sent] --> [Internet drops again] -->
+     * [No /sync response is triggered | home server can even replied with /sync but never arrived while we are offline]
+     *
+     * So the state until now is that we have 7 pending events to send and 3 sent but not received them back from /sync
+     * Subsequently, those 3 local messages will not be deleted while there is no transactionId from the /sync
+     *
+     * lets continue:
+     * [Now lets assume that in the same room another user sent 15 events] -->
+     * [We are finally back online!] -->
+     * [We will receive the 10 latest events for the room and of course sent the pending 7 messages] -->
+     * Now /sync response will NOT contain the 3 local messages so our events will stuck in the device.
+     *
+     * Someone can say, yes but it will come with the rooms/{roomId}/messages while paginating,
+     * so the problem will be solved. No that is not the case for two reasons:
+     *   1. rooms/{roomId}/messages response do not contain the unsignedData.transactionId so we cannot know which event
+     *   to delete
+     *   2. even if transactionId was there, currently we are not deleting it from the pagination
+     *
+     * ---------------------------------------------------------------------------------------------
+     * While we cannot know when a specific event arrived from the pagination (no transactionId included), after each room /sync
+     * we clear all SENT events, and we are sure that we will receive it from /sync or pagination
