Deprecated Methods
Method and Description
io.netty.channel.ChannelFlushPromiseNotifier.add(ChannelPromise, int) use `ChannelFlushPromiseNotifier.add(ChannelPromise, long)`
io.netty.channel.group.ChannelGroup.deregister() This method will be removed in the next major feature release. Deregister all `Channel`s in this group from their `EventLoop`. Please note that this operation is asynchronous as `Channel.deregister()` is.
io.netty.channel.group.ChannelGroup.deregister(ChannelMatcher) This method will be removed in the next major feature release. Deregister all `Channel`s in this group from their `EventLoop` that match the given `ChannelMatcher`. Please note that this operation is asynchronous as `Channel.deregister()` is.
