+---
+Bitcoin version 0.5.3 is now available for download at:
+<http://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.5.3/>
+
+This is a bugfix-only release based on 0.5.1.
+It also includes a few protocol updates.
+
+Please report bugs using the issue tracker at github:
+<https://github.com/bitcoin/bitcoin/issues>
+
+PROTOCOL UPDATES
+----------------
+
+* BIP 30: Introduce a new network rule: "a block is not valid if it contains
+a transaction whose hash already exists in the block chain, unless all that
+transaction's outputs were already spent before said block" beginning on
+March 15, 2012, 00:00 UTC.
+
+* On testnet, allow mining of min-difficulty blocks if 20 minutes have gone
+by without mining a regular-difficulty block. This is to make testing
+Bitcoin easier, and will not affect normal mode.
+
+BUG FIXES
+---------
+
+* Limit the number of orphan transactions stored in memory, to prevent a
+potential denial-of-service attack by flooding orphan transactions. Also
+never store invalid transactions at all.
+
+* Fix possible buffer overflow on systems with very long application data
+paths. This is not exploitable.
+
+* Resolved multiple bugs preventing long-term unlocking of encrypted wallets
+(issue #922).
+
+* Only send local IP in "version" messages if it is globally routable (ie,
+not private), and try to get such an IP from UPnP if applicable.
+
+* Reannounce UPnP port forwards every 20 minutes, to workaround routers
+expiring old entries, and allow the -upnp option to override any stored
+setting.
+
+* Skip splash screen when -min is used, and fix Minimize to Tray function.
+
+* Do not blank "label" in Bitcoin-Qt "Send" tab, if the user has already
+entered something.
+
+* Correct various labels and messages.
+
+* Various memory leaks and potential null pointer deferences have been
+fixed.
+
+* Handle invalid Bitcoin URIs using "bitcoin://" instead of "bitcoin:".
+
+* Several shutdown issues have been fixed.
+
+* Revert to "global progress indication", as starting from zero every time
+was considered too confusing for many users.
+
+* Check that keys stored in the wallet are valid at startup, and if not,
+report corruption.
+
+* Enable accessible widgets on Windows, so that people with screen readers
+such as NVDA can make sense of it.
+
+* Various build fixes.
+
+* If no password is specified to bitcoind, recommend a secure password.
+
+* Automatically focus and scroll to new "Send coins" entries in Bitcoin-Qt.
+
+* Show a message box for --help on Windows, for Bitcoin-Qt.
+
+* Add missing "About Qt" menu option to show built-in Qt About dialog.
+
+* Don't show "-daemon" as an option for Bitcoin-Qt, since it isn't
+available.
+
+* Update hard-coded fallback seed nodes, choosing recent ones with long
+uptime and versions at least 0.4.0.
+
+* Add checkpoint at block 168,000.
