+## 0.5.11 (2018-07-14)
+
+* `Object.checksum(mixed)` will now treat Dates & Numbers differently
+* `Object.checksum(mixed)` will now correctly hash node Buffers
+* Add `Buffer` support to `Object.alike(a, b)`
+* Make `Object.alike(a, b)` not sort arrays when doing a checksum
+* Fix `Object.alike(a, b)` treating null as regular objects
+* Add a very basic Symbol polyfill for IE11
+* Add `Blast.alikeSymbol` property, which `Object.alike` uses for comparing likeness
