Bitcoin XT Release 0.11.0E

• Thin blocks speed block download, enabled by default
• Supports and votes for 2MB hard fork (identical to Classic). BIP101 reverted.
• Switch to secp256k1 custom bitcoin ECC library
• Random mempool eviction reverted, low-fee txes evicted when mempool full
• Mempool expiration at 72h (identical to Core)
• Configurable user-agent comment
• Display coinjoins properly in GUI
• LevelDB anti-corruption fix (Windows platforms)
• Gracefully handle migration from obfuscated (Core v0.12) chainstate

• GUI-configurable upload and download network speed (bandwidth) limits

This release fixes a buffer overflow in the integrated UPNP support.

Bitcoin XT 0.11B contains the following changes and upgrades:

• For miners, compatibility with tools like cgminer that include 64-bit incompatible JSON parsers
• A size limited mempool for "stress test" resistance. Use the -maxmempooltx flag to control how many transactions are allowed in the mempool at once (default is 50000 or about 25 blocks worth). When there's an overflow, a random transaction and its children will be removed to make room.
• Now defaults to trusting the system clock, to resolve potential issues with lying peers causing clock drift.
• Stealth mode (activated with -stealth-mode flag), to make XT appear as Core on the network. Stealth mode can be used to hide from DDoS attacks but disables some protocol upgrades and other DoS attack fixes, so should only be used if you need it.
• Improvements to the IP priorities code. You can now load IP priorities from files on disk, if you find certain IP ranges using up all your sockets.
• XT patchlevel now appears more consistently.

Bitcoin XT adds support for:

• Bigger block hard fork
• Misc DoS fixes
• Double spend relaying
• More DNS seeds

on top of the regular Bitcoin Core 0.11 release.

Bitcoin XT release based on upstream version 0.10.2

Note that this does not contain any block size related changes.

This release corresponds to the upstream 0.10.0 final release.

This release is based on Bitcoin Core 0.10rc3 and contains one new patch, which adds more DNS seeds and removes one that is serving ancient static IPs (which are all dead but one).

This update contains important bug fixes.
