+- Update scientific to version 0.3.6.2.
+  * Due to a regression introduced in 0.3.4.14 the RealFrac methods
+    and floatingOrInteger became vulnerable to a space blowup when
+    applied to scientifics with huge exponents. This has now been
+    fixed again.
+
+  * Fix build on GHC < 8.
+
+  * Make the methods of the Hashable, Eq and Ord instances safe to
+  use when applied to scientific numbers coming from untrusted
+  sources. Previously these methods first converted their arguments
+  to Rational before applying the operation. This is unsafe because
+  converting a Scientific to a Rational could fill up all space and
+  crash your program when the Scientific has a huge base10Exponent.
+
+  Do note that the hash computation of the Hashable Scientific
+  instance has been changed because of this improvement!
+
+  Thanks to Tom Sydney Kerckhove (@NorfairKing) for pushing me to
+  fix this.
+
+  * fromRational :: Rational -> Scientific now throws an error
+  instead of diverging when applied to a repeating decimal. This
+  does mean it will consume space linear in the number of digits of
+  the resulting scientific. This makes "fromRational" and the other
+  Fractional methods "recip" and "/" a bit safer to use.
+
+  * To get the old unsafe but more efficient behaviour the following
+  function was added: unsafeFromRational :: Rational -> Scientific.
+
+  * Add alternatives for fromRationalRepetend:
+
+    fromRationalRepetendLimited
+        :: Int -- ^ limit
+        -> Rational
+        -> Either (Scientific, Rational)
+                (Scientific, Maybe Int)
+
+    and:
+
+    fromRationalRepetendUnlimited
+        :: Rational -> (Scientific, Maybe Int)
+
+    Thanks to Ian Jeffries (@seagreen) for the idea.
+
+  * Dropped upper version bounds of dependencies
+    because it's to much work to maintain.
