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.
