Notable changes

Notable changes since 0.10.3

BIP65 soft fork to enforce OP_CHECKLOCKTIMEVERIFY opcode

[BIP65]: https://github.com/bitcoin/bips/blob/master/bip-0065.mediawiki
Fix buffer overflow in bundled upnp
------------------------------------
Windows bug fix for corrupted UTXO database on unclean shutdowns
----------------------------------------------------------------
Bundled miniupnpc was updated to 1.9.20151008. This fixes a buffer overflow in
the XML parser during initial network discovery.
Several Windows users reported that they often need to reindex the
entire blockchain after an unclean shutdown of Litecoin Core on Windows
(or an unclean shutdown of Windows itself). Although unclean shutdowns
remain unsafe, this release no longer relies on memory-mapped files for
the UTXO database, which significantly reduced the frequency of unclean
shutdowns leading to required reindexes during testing.
Details can be found here: http://talosintel.com/reports/TALOS-2015-0035/
For more information, see: <https://github.com/bitcoin/bitcoin/pull/6917>
This applies to the distributed executables only, not when building from source or
using distribution provided packages.
Other fixes for database corruption on Windows are expected in the
next major release.
Additionally, upnp has been disabled by default. This may result in a lower
number of reachable nodes on IPv4, however this prevents future libupnpc
vulnerabilities from being a structural risk to the network
(see https://github.com/bitcoin/bitcoin/pull/6795).
Test for LowS signatures before relaying
-----------------------------------------
Make the node require the canonical 'low-s' encoding for ECDSA signatures when
relaying or mining. This removes a nuisance malleability vector.
Consensus behavior is unchanged.
If widely deployed this change would eliminate the last remaining known vector
for nuisance malleability on SIGHASH_ALL P2PKH transactions. On the down-side
it will block most transactions made by sufficiently out of date software.
Unlike the other avenues to change txids on transactions this
one was randomly violated by all deployed litecoin software prior to
its discovery. So, while other malleability vectors where made
non-standard as soon as they were discovered, this one has remained
permitted. Even BIP62 did not propose applying this rule to
old version transactions, but conforming implementations have become
much more common since BIP62 was initially written.
Litecoin Core has produced compatible signatures since the 0.9 development
branch, but this didn't make it into a release until 0.10. Both litecoinj
and Electrum have been more recently updated.
This does not replace the need for BIP62 or similar, as miners can
still cooperate to break transactions. Nor does it replace the
need for wallet software to handle malleability sanely[1]. This
only eliminates the cheap and irritating DOS attack.

0.10.3 Change log
0.10.4 Change log
=================
This release is based upon Bitcoin Core v0.10.3. Their upstream changelog applies to us and
is included in as separate release-notes. This section describes the Litecoin-specific differences.
This release is based upon Bitcoin Core v0.10.4. Their upstream changelog applies to us and
is included in as separate release-notes, see: [Release Notes](release-notes.md).
This section describes the Litecoin-specific differences.
- Adjusted default confirmation target value (nTxConfirmTarget) which is used for transaction fee
calculation, resulting in lower and more accurate fees. This mainly impacts users who use
litecoind via litecoin-cli or the RPC service to send transactions as GUI (Qt) users
already have the option to change their fee preferences.
- Fixed OSX notification bug displaying incorrect icon.
- Fixed OSX Chinese language Unicode character display bug.
- Fixed make check testing suite.
- Updated Qt translations.
- Updated build instructions for OSX and Unix.
- Add BIP65 CHECKLOCKTIMEVERIFY softfork.
- Added BIP65 CHECKLOCKTIMEVERIFY softfork.
- Increased OP_RETURN relay size to 80 bytes.
