- [mpd] Lua 5.3 compatibility (for real this time); also correct a typo
|
||||
- [pkg,weather,contrib/btc] Allow function call without Awesome
|
||||
- [pkg] Use more updated front-ends for Debian/Ubuntu (apt) and Fedora (dnf)
|
||||
|
||||
Removed:
|
||||
|
||||
- `helpers.sysctl` and `helpers.sysctl_table` were removed in favour of
|
||||
`helpers.sysctl_async`.
