Gemfile:
- Upgrade to Jekyll 3.x (3.0.1 tested). This brings several new
features I want to use, most notably *collections* which allows us
to add blog-like collections. I've converted the `_releases` and
`_alerts` pages into collections, although their plugins are
maintained to handle the Download and Active Alert features.
- Upgrade to latest Kramdown.
- Lock Less at 2.4.0. This prevents breaking our Less plugin. Jekyll
3.x provides native support for SCSS, so we may want to switch to
that in time.
- Lock HTML Proofer at 2.1.0. The most recent version was taking
forever to check our pages (I never actually got it to complete).
I'll look into it when I get more time.
Makefile:
- New `make clean` command. Jekyll 3.x by default attempts to do
incremental rebuilds. The new `jekyll clean` command cleans up the
metadata necessary for than so that a full build is performed, and
this new `make clean` command is a wrapper around it so that we
automatically do full rebuilds in the relevant cases. Note: our
plugins aren't fully compatible with the incremental rebuilds, but
I'd like to fix that in the future.
- Remove WEBrick hack to enable previewing with default URL paths (/
instead of /index.html).
- Filter out compliants from Rouge
README.md:
- Now that Alerts (_alerts) are part of a collection, the file names
are no longer parsed for dates, so instructions on adding the date
to the YAML metadata have been added.
_alerts/*:
- Now that alerts are part of a collection, the file names are no
longer parsed to provide dates, so a `date:` field has been added to
the YAML metadata.
_config.yml:
- Some variables renamed per upgrade instructions.
- Switched from old default syntax highlighter Pygments to new default
Rouge. I tried to use Rouge options to keep new output as similar
to old output as possible to making diffing easy, but Rouge adds
extra CSS class info.
- Move `_alerts` and `_releases` into Jekyll 3.x "collections", which
provide the organizational features we were using plugins to
manange. I haven't removed the old plugins because we still use
some of their features (alerts.rb provides active issue and banner
features; releases.rb provides info to Download page)
- _layouts/* can no longer provide default global metadata; that is now
provided in the new `defaults:` section in _config.yml.
_layouts/*:
- Default metadata can no longer be provided in the layout files for
collections, so I've removed it and left a message to see
_config.yml.
_plugins/*:
- Remove filter_for.rb. It's completely broken on Jekyll 3.x because
of changes to Liquid which prevent adding new arguments to the
inherited Liquid::For class. Existing uses of filter_for have been
migrated to built-in for loops prefaced by sorts.
- Remove remove-html-extension.rb: at it said in the comments, this
was a temporary hack to get us to Jekyll 3.0.
_releases/*:
- Rename all the files: prefix a v to the file name so the output html
(e.g. v10.0.0.html) is the same as the source filename (e.g.
v10.0.0.md). This is necessary to migrate them to a Jekyll collection.
- Remove %v from titles: we have to explicitly set the title, like we
used to. Again required for migration to collections.
_templates/events.html & en/rss/events.rss:
- Sort events by date and then loop with regular for loop rather than
filter_for
en/alerts.html & en/rss/alerts.rss:
- Sort alerts by date and then loop with regular for loop rather than
filter_for
en/bitcoin-core/index.md & en/version-history.html & en/rss/releases.rss:
- Sort alerts by date and then loop with regular for loop rather than
filter_for

{% githubify https://github.com/bitcoin/bitcoin %} Bitcoin Core version 0.11.1 is now available from:
https://bitcoin.org/bin/bitcoin-core-0.11.1/
This is a new minor version release, bringing security fixes. It is recommended to upgrade to this version as soon as possible.

Upgrading and downgrading
How to Upgrade
If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer (on Windows) or just copy over /Applications/Bitcoin-Qt (on Mac) or bitcoind/bitcoin-qt (on Linux).
Downgrade warning
Because release 0.10.0 and later makes use of headers-first synchronization and parallel block download (see further), the block files and databases are not backwards-compatible with pre-0.10 versions of Bitcoin Core or other software:
-
Blocks will be stored on disk out of order (in the order they are received, really), which makes it incompatible with some tools or other programs. Reindexing using earlier versions will also not work anymore as a result of this.
-
The block index database will now hold headers for which no block is stored on disk, which earlier versions won't support.
If you want to be able to downgrade smoothly, make a backup of your entire data directory. Without this your node will need start syncing (or importing from bootstrap.dat) anew afterwards. It is possible that the data from a completely synchronised 0.10 node may be usable in older versions as-is, but this is not supported and may break as soon as the older version attempts to reindex.
This does not affect wallet forward or backward compatibility. There are no known problems when downgrading from 0.11.x to 0.10.x.
Notable changes
Fix buffer overflow in bundled upnp
Bundled miniupnpc was updated to 1.9.20151008. This fixes a buffer overflow in the XML parser during initial network discovery.
Details can be found here: http://talosintel.com/reports/TALOS-2015-0035/
This applies to the distributed executables only, not when building from source or using distribution provided packages.
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 bitcoin 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.
Bitcoin Core has produced compatible signatures since a28fb70e in September 2013, but this didn't make it into a release until 0.9 in March 2014; Bitcoinj has done so for a similar span of time. Bitcoinjs 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.

Minimum relay fee default increase
The default for the -minrelaytxfee setting has been increased from 0.00001
to 0.00005.
This is necessitated by the current transaction flooding, causing outrageous memory usage on nodes due to the mempool ballooning. This is a temporary measure, bridging the time until a dynamic method for determining this fee is merged (which will be in 0.12).
(see https://github.com/bitcoin/bitcoin/pull/6793, as well as the 0.11 release notes, in which this value was suggested)
