 ## Unreleased
 
+### Added
+
+- `test_persistent_tasks` now accepts an optional `succeed_on_precompilable_error::Bool=true` to control the behavior on the occurrence of a `PrecompilableError`. ([#285])
+
 ### Changed
 
 - The output of `test_ambiguities` now gets printed to stderr instead of stdout. ([#281])

 - `tmax::Real = 5`: the maximum time (in seconds) to wait after loading the
   package before forcibly shutting down the precompilation process (triggering
   a test failure).
+- `succeed_on_precompilable_error::Bool = true`: If true, the test will pass if
+  the package has a precompilation error. The intended use is to keep your CI
+  green even if the case that a new release of a dependency introduces a

 - `expr::Expr = quote end`: An expression to run in the precompile package.
