 - feat: `continue` statements. Like Dafny's `break` statements, these come in two forms: one that uses a label to name the continue target and one that specifies the continue target by nesting level. See section [19.2](https://dafny-lang.github.io/dafny/DafnyRef/DafnyRef#sec-break-continue) of the Reference Manual. (https://github.com/dafny-lang/dafny/pull/1839)
 - feat: The keyword syntax for functions will change in Dafny version 4. The new command-line option `/functionSyntax` (see `/help`) allows early adoption of the new syntax. (https://github.com/dafny-lang/dafny/pull/1832)
 - feat: Attribute `{:print}` declares that a method may have print effects. Print effects are enforced only with `/trackPrintEffects:1`.
