This also includes buffer modifications to have a larger read buffer and IRCv3 implementations (partial or not) for: labeled-response, msgid, server-time, batch and account-tag. As said, it is the initial and partial implementation. There are still various FIXME's and TODO's, the API of various functions may still change (actually that is true for the next months, even) and some stuff is currently in the core that will be moved to modules.

|
* version of that remote include will be used, and the ircd will still boot

|
* your network. Previously, servers would be unable to boot or rehash when
|
|
* the webserver was down, which would be a big problem (often unacceptable).
|
|
* The latest version of fetched urls are cached in the cache/ directory as
|
|
* cache/<md5 hash of url>.
|
|
* Obviously, if there's no 'latest version' and an url fails, the ircd will
|
|
* still not be able to boot. This would be the case if you added or changed
|
|
* the path of a remote include and it's trying to fetch it for the first time.
