Dafny 3.5.0

[robin-aws]

• 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 of the Reference Manual. (feat: continue statements #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. (Function keywords refresh #1832)
• feat: Attribute {:print} declares that a method may have print effects. Print effects are enforced only with /trackPrintEffects:1.
• feat: Add support for non-interactive solvers that need all SMT-Lib input in one batch (enabled with /proverOpt:BATCH_MODE=true). Inherited from Boogie 2.13 (Refactor solver process handling to allow non-interactive mode boogie-org/boogie#512).
• fix: Allow /verificationLogger and /vcsCores to be usable together. Inherited from Boogie 2.13 (Support XML generation with /vcsCores boogie-org/boogie#515).
• fix: Plug two memory leaks in Dafny's verification server. (Memory leak in implementation of RevealableTypeDeclHelper #1858, Incorrect programId passed to Boogie causes memory leak in LSP server #1863)
• fix: No warning "File contains no code" if a file only contains a submodule (fix: File contains no code even when there is code in prefixed modules #1840)
• fix: Stuck in verifying in VSCode - support for verification cancellation (fix: "Stuck on Verifying..." #1771)
• fix: export-reveals of function-by-method now allows the function body to be ghost (fix: Don’t entirely delete by-method part in export scope checks #1855)
• fix: Regain C# 7.3 compatibility of the compiled code. (Fix: Lower C# runtime version to 7.3 #1877)
• fix: The error "assertion violation" is replaced by the better wording "assertion might not hold". This indicates better that the verifier is unable to prove the assertion. (fix: assertion may not hold #1862)
