+# 4.6.0
+
+## New features
+
+- Add a check to `dafny run` that notifies the user when a value that was parsed as a user program argument, and which occurs before a `--` token, starts with `--`, since this indicates they probably mistyped a Dafny option name. (https://github.com/dafny-lang/dafny/pull/5097)
+
+- Add an option --progress that can be used to track the progress of verification. (https://github.com/dafny-lang/dafny/pull/5150)
+
+- Add the attribute `{:isolate_assertions}`, which does the same as `{:vcs_split_on_every_assert}`. Deprecated `{:vcs_split_on_every_assert}` (https://github.com/dafny-lang/dafny/pull/5247)
+
+## Bug fixes

+
+- Fixed links associated with the standard libraries. (https://github.com/dafny-lang/dafny/pull/5176)
