+- update to version 3.38.0:
+  * This release overhauls the health check system in a variety of
+    small ways. It adds no new features, but is nevertheless a minor
+    release because it changes which tests are likely to fail health
+    checks.
+  * The most noticeable effect is that some tests that used to fail
+    health checks will now pass, and some that used to pass will
+    fail. These should all be improvements in accuracy. In particular:
+    + New failures will usually be because they are now taking into
+      account things like use of data() and assume() inside the test
+      body.
+    + New failures may also be because for some classes of example the
+      way data generation performance was measured was artificially
+      faster than real data generation (for most examples that are
+      hitting performance health checks the opposite should be the
+      case).
+    + Tests that used to fail health checks and now pass do so because
+      the health check system used to run in a way that was subtly
+      different than the main Hypothesis data generation and lacked
+      some of its support for e.g. large examples.
+  * If your data generation is especially slow, you may also see your
+    tests get somewhat faster, as there is no longer a separate health
+    check phase. This will be particularly noticeable when rerunning
+    test failures.
