 [//]: # "Changes:"
 
+- Changed `std/osfiles.copyFile` to allow to specify `bufferSize` instead of a hardcoded one.
+- Changed `std/osfiles.copyFile` to use `POSIX_FADV_SEQUENTIAL` hints for kernel-level aggressive sequential read-aheads.
 
 [//]: # "Additions:"
 
+- 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 initalize
+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.
+
 [//]: # "Deprecations:"
 
+- Deprecates `system.newSeqUninitialized`, which is replaced by `newSeqUninit`.
 
 [//]: # "Removals:"
 
 
 ## Language changes
 
-
+- `noInit` can be used in types and fields to disable member initializers in the C++ backend. 
 
 ## Compiler changes
 
-
-
+- `--nimcache` using a relative path as the argument in a config file is now relative to the config file instead of the current directory.
 
 ## Tool changes
 
+- koch now allows bootstrapping with `-d:nimHasLibFFI`, replacing the older option of building the compiler directly w/ the `libffi` nimble package in tow.
