# Perl
- Add `$client->GetPEQZoneFlags()`.
- Add `$client->GetZoneFlags()`.

# Lua
- Add `client:GetPEQZoneFlags()`.
- Add `client:GetZoneFlags()`.

# Notes
- Allows operators to get a list of all PEQ/zone flags to be looped through or listed out easily without having to have a list of individual zone IDs to check or otherwise.

* Update zoning.cpp
