See + [OpenMP documentation](https://www.openmp.org/wp-content/uploads/OpenMP-4.5-1115-CPP-web.pdf). + + The default annotation is `parallel for`, if you used OpenMP without annotation + the change is transparent, if you used annotations you will have to prefix + your previous annotations with `parallel for`. + +- The `unchecked` pragma was removed, instead use `system.UncheckedArray`. +- The undocumented ``#? strongSpaces`` parsing mode has been removed. +- The `not` operator is now always a unary operator, this means that code like + ``assert not isFalse(3)`` compiles. + #### Breaking changes in the standard library +- `osproc.execProcess` now also takes a `workingDir` parameter. + +- `options.UnpackError` is no longer a ref type and inherits from `System.Defect` instead of `System.ValueError`. + +- nre's `RegexMatch.{captureBounds,captures}[]` no longer return `Option` or + `nil`/`""`, respectivly.

Instead uncaptured entries are left empty. Use + `Table.getOrDefault()` if you need defaults. + +- nre's `RegexMatch.captures.{items,toSeq}` now returns an `Option[string]` + instead of a `string`. With the removal of `nil` strings, this is the only + way to indicate a missing match. Inside your loops, instead of `capture == + ""` or `capture == nil`, use `capture.isSome` to check if a capture is + present, and `capture.get` to get its value. + +- nre's `replace()` no longer throws `ValueError` when the replacement string + has missing captures. It instead throws `KeyError` for named captures, and + `IndexError` for un-named captures. This is consistant with + `RegexMatch.{captureBounds,captures}[]`. #### Breaking changes in the compiler +- The compiler now implements the "generic symbol prepass" for `when` statements + in generics, see bug #8603.

The `dumpLisp` macro in this module now outputs an + indented proper Lisp, devoid of commas. + +- In `strutils` empty strings now no longer matched as substrings + anymore. + +- Complex type is now generic and not a tuple anymore. + +- The `ospaths` module is now deprecated, use `os` instead. Note that + `os` is available in a NimScript environment but unsupported + operations produce a compile-time error. + +- The `parseopt` module now supports a new flag `allowWhitespaceAfterColon` + (default value: true) that can be set to `false` for better Posix + interoperability.
