 - Added `newStringUninit` to system, which creates a new string of length `len` like `newString` but with uninitialized content.

+- Added `setLenUninit` to system, which doesn't initialize
 slots when enlarging a sequence.
 - Added `hasDefaultValue` to `std/typetraits` to check if a type has a valid default value.
 - Added Viewport API for the JavaScript targets in the `dom` module.
 - Added `toSinglyLinkedRing` and `toDoublyLinkedRing` to `std/lists` to convert from `openArray`s.
 - ORC: To be enabled via `nimOrcStats` there is a new API called `GC_orcStats` that can be used to query how many
   objects the cyclic collector did free. If the number is zero that is a strong indicator that you can use `--mm:arc`
   instead of `--mm:orc`.
+- A `$` template is provided for `Path` in `std/paths`.
+- `std/hashes.hash(x:string)` changed to produce a 64-bit string `Hash` (based
+on Google's Farm Hash) which is also often faster than the present one.  Define
+`nimStringHash2` to get the old values back.  `--jsbigint=off` mode always only
+produces the old values.  This may impact your automated tests if they depend
+on hash order in some obvious or indirect way.  Using `sorted` or `OrderedTable`
+is often an easy workaround.
