- In `std/os`, `getHomeDir`, `expandTilde`, `getTempDir`, `getConfigDir` now do not include trailing `DirSep`,
unless `-d:nimLegacyHomeDir` is specified (for a transition period).
- On POSIX systems, the default signal handlers used for Nim programs (it's
used for printing the stacktrace on fatal signals) will now re-raise the
signal for the OS default handlers to handle.
This lets the OS perform its default actions, which might include core
dumping (on select signals) and notifying the parent process about the cause
of termination.
- On POSIX systems, we now ignore `SIGPIPE` signals, use `-d:nimLegacySigpipeHandler`
for previous behavior.
## Standard library additions and changes
- Added support for parenthesized expressions in `strformat`

- Added `system.prepareStrMutation` for better support of low

implementation.
