 * `ChannelManager`s written with LDK 0.0.119 are no longer readable by versions
   of LDK prior to 0.0.113. Users wishing to downgrade to LDK 0.0.112 or before
   can read an 0.0.119-serialized `ChannelManager` with a version of LDK from
   0.0.113 to 0.0.118, re-serialize it, and then downgrade.
Stop writing signer data as a part of channels This breaks backwards compatibility with versions of LDK prior to 0.0.113 as they expect to always read signer data. This also substantially reduces allocations during `ChannelManager` serialization, as we currently don't pre-allocate the `Vec` that the signer gets written in to. We could alternatively pre-allocate that `Vec`, but we've been set up to skip the write entirely for a while, and 0.0.113 was released nearly a year ago. Users downgrading to LDK 0.0.112 and before at this point should not be expected. 2023-11-04 23:02:18 +00:00			* `ChannelManager`s written with LDK 0.0.119 are no longer readable by versions
