HCL now uses a newer version of the upstream cty library which has improved treatment of unknown values: it can now track additional optional information that reduces the range of an unknown value, which allows some operations against unknown values to return known or partially-known results. (#590)
Note: This change effectively passes on cty's notion of backward compatibility whereby unknown values can become "more known" in later releases. In particular, if your caller is using cty.Value.RawEquals in its tests against the results of operations with unknown values then you may see those tests begin failing after upgrading, due to the values now being more "refined".
If so, you should review the refinements with consideration to the cty refinements docs and update your expected results to match only if the reported refinements seem correct for the given situation. The RawEquals method is intended only for making exact value comparisons in test cases, so main application code should not use it; use Equals instead for real logic, which will take refinements into account automatically.
