April 14, 2021
The Bitcoin Cash Node (BCHN) project is pleased to announce its major release version 23.0.0.
This release implements the May 15, 2021 network upgrade. It contains the removal of the unconfirmed transaction chain limits, enabling of multiple OP_RETURN (while keeping the total size limit of data carrier), introduction of Double Spend Proofs (beta), a lifting of the default soft limit for mining to 8MB, and a number of bugfixes and performance improvements.
BCHN users should consider this update as mandatory prior to May 15, 2021. This is because of the coordination of the new policy rules around transaction chain limits and standardness of multiple OP_RETURN. The v22.2.0 software will expire some functionality on May 15, and will start to warn about ahead of time, from April 15, 2021 onward.

Hello @ShinShin,
The changes planned for May 15 are non-forking changes. They are scheduled to activate when Median Time Past (MTP) >= 1621080000 .
Thank you for quick response.
I run an exchange. So that means I don't need to update to v23.0.0?
BCHN users should consider this update as mandatory prior to May 15, 2021.
You do need to upgrade if you are running an economic node such as an exchange.
This is still a network upgrade, although not a fork.
The upgrade affects which transactions are accepted into your node's mempool, so as an exchange you want your nodes to adhere to the same rules about this as the rest of the network.
Also, the v22.x.0 will expire its RPC functionality on May 15, 2021 unless an override parameter is given - so we highly recommend to upgrade to v23.0.0 well ahead of that date.

Updates are always welcome
This is exciting news! No more chained limit, more op returns, and better scaling? Im seriously sorry I ever doubted you guys. This is the sh**t right here!!!
I do not disagree with the features. In fact they seem like good news to me.
But... didn't you propose that the next update would be in May 2022?
The date of May 2021 was already encoded by ABC under the date & the name "Tachyon". We decided to use this date for the upgrade of the two aspects which does not modify consensus rules (so no hard fork split risk):
However, we also proposed that the next date for a consensus upgrade be in May 2022 - that is correct and is our current perspective. There are a number of consensus changed being reviewed for May next year.
On which block number this fork will take place?
