=========================
* Security enhancement: refer to orphan blocks by hash, not height.
* Fixed bugs affecting new chains defined via the configuration.
* Warn, do not exit, if a block file is missing or unparsable.
* Abe parses the new merged-mining block field, CAuxPow.
* Decrement the value returned by getblockcount for compatibility.
* Bug fix: remove '-' from parenthesized amounts.
* Fixed previous/next block links on /chain/CHAIN/b/NUMBER pages.
* Accept "var += val" in configuration as equivalent to "var = val"
where "var" has not been defined.
* Added --commit-bytes option to adjust the database commit interval.
* Minor robustness and cosmetic improvements.
Major changes from 0.3 to 0.4 (2011-07-04 to 2011-07-15)
========================================================
* The chain summary page (the one listing several blocks in the same
chain) loads much faster than before.
* Address search accepts an initial substring, still without storing
addresses in the database.
* FastCGI support has matured. See README-FASTCGI.txt for setup.
* Abe supports Weeds currency natively. Weeds info:
http://forum.bitcoin.org/index.php?topic=24209.0
* The "datadir" configuration directive can add a new currency without
changes to Python code.
* "auto-agpl" provides a link to download the source directory: a
license compliance aid for those not wishing to use a Github fork.
* /chain/Bitcoin/q/getblockcount: first of (I hope) many
BBE-compatible APIs.
* Several small fixes and speedups.
