+Bitcoin ABC version 0.28.9 is now available from:
 
-  <https://download.bitcoinabc.org/0.28.8/>
+  <https://download.bitcoinabc.org/0.28.9/>
 
-This release includes the following features and fixes:
-
-Wallet changes
---------------
-
-Bitcoin ABC will no longer automatically create new wallets on startup. It will
-load existing wallets specified by `-wallet` options on the command line or in
-`bitcoin.conf` or `settings.json` files. And by default it will also load a
-top-level unnamed ("") wallet. However, if specified wallets don't exist,
-Bitcoin ABC will now just log warnings instead of creating new wallets with
-new keys and addresses like previous releases did.
-New wallets can be created through the GUI , through the `bitcoin-cli createwallet`
-or `bitcoin-wallet create` commands, or the `createwallet` RPC.
-
-
-P2P and network changes
------------------------
-
-To address a potential denial-of-service, the logic to download headers from peers
-has been reworked. This is particularly relevant for nodes starting up for the first
-time (or for nodes which are starting up after being offline for a long time).
-
-Whenever headers are received from a peer that have a total chainwork that is either
-less than the node’s -minimumchainwork value or is sufficiently below the work at the
-node’s tip, a “presync” phase will begin, in which the node will download the peer’s
-headers and verify the cumulative work on the peer’s chain, prior to storing those
-headers permanently. Once that cumulative work is verified to be sufficiently high,
-the headers will be redownloaded from that peer and fully validated and stored.
-
-This may result in initial headers sync taking longer for new nodes starting up for
-the first time, both because the headers will be downloaded twice, and because the
-effect of a peer disconnecting during the presync phase (or while the node’s best
-headers chain has less than -minimumchainwork), will result in the node needing to
-use the headers presync mechanism with the next peer as well.
-
-
-Updated RPC
------------
-
-The getpeerinfo RPC has been updated with a new `presynced_headers` field, indicating
-the progress on the presync phase mentioned in the “P2P and network changes” section
-above.
+This is a maintenance release with no user-visible change.
