**Breaking changes**
The livechat v13 introduced a new library to handle regular expressions in forbidden words, to avoid
[ReDOS](https://en.wikipedia.org/wiki/ReDoS) attacks.
Unfortunately, this library was not able to install itself properly on some systems, and some admins were not able
to install the livechat plugin.
That's why we have disabled this library in v14, and introduce a new settings to enable regexp in forbidden words.
By default this settings is disabled, and your users won't be able to use regexp in their forbidden words.
The risk by enabling this feature is that a malicious user could cause a denial of service for the chat bot, by using a
special crafted regular expression in their channel options, and sending a special crafter message in one of their
rooms. If you trust your users (those who have rights to livestream), you can enable the settings. Otherwise it is not
recommanded. See the documentation for more informations.
**Minor changes and fixes**
* Channel's forbidden words: new "enable" column.
* New settings to enable regular expressions for channel forbidden words.
* "Channel advanced configuration" settings: removing the "experimental feature" label.
There was a regression some months ago in the "bot timer" functionnality.
In the channels settings, the delay between two quotes is supposed to be in minutes, but in fact we applied seconds.
We don't have any way to detect if the user meant seconds or minutes when they configured their channels (it depends if it was before or after the regression).
So we encourage all streamers to go through their channel settings, check the frequency of their bot timers (if enabled), set them to the correct value, and save the form.
Users must save the form to be sure to apply the correct value.
