New Abe feature: Standard Bitcoin multisig and pay-to-script-hash (P2SH) support is in the master branch, thanks to Jouke's generous sponsorship.  This old post describes what it means.  Upgrade could take a few minutes to over an hour on a fully loaded Bitcoin database as Abe scans for output scripts not yet assigned an address.  Always backup your important data prior to upgrading.

Master also has the beginning of a test suite covering SQLite, MySQL, and PostgreSQL, which you can run by installing pytest and running py.test in the bitcoin-abe directory.  To test with MySQL and PostgreSQL requires those databases' respective instance creation tools.  Specify ABE_TEST=quick or ABE_TEST_DB=sqlite in the process environment to test only with a (much faster) SQLite in-memory database.  The tests cover block, tx, and address pages, prior to HTML rendering.
