v2.17.0
Enhancements
-
HCL now uses a newer version of the upstream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 usingcty.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. TheRawEquals
method is intended only for making exact value comparisons in test cases, so main application code should not use it; useEquals
instead for real logic, which will take refinements into account automatically.
