+ New Features:
29

30
+ - ``mongosync`` now supports migrating documents that have an empty timestamp
31
+ values, such as Timestamp(0,0) for source clusters using MongoDB version 6.0
32
+ or later.
33
+
34
+ - Added a ``stdin`` disclaimer to the ``mongosync`` executable regarding
35
+ verification. Users must to accept this disclaimer before ``mongosync``
36
+ can run.
37
+
38
+ - Added ``--acceptDisclaimer`` flag for users that have previously read the
39
+ disclaimer to bypass it.
40
+
41
+ - Added a memory check in the ``/start`` endpoint for enabling verification.
42
+ Verification requires 10 GB of base memory and 0.5 GB per 1 million documents.
43
+
44
+ Optimizations:
45
+
46
+ - Increased internal timeout to reduce the occurrence of timeout failures during
47
+ initialization
