    Finalize version 1.4.1, with the following major changes relative to 1.4.0:
     * Lock more around establishing backend database connections,
       eliminating races that may have led to 1.4.0's frequent crashes.
     * Log details of apparent badly formatted input.

2012-01-06 14:59:21:
    Finalize version 1.4.0, with the following major changes relative to 1.3.1:
     * Advance to 8.0 stable components, picking up various improvements in
       base libraries.  (Also, build only 64-bit binaries, using GCC 4.4.2.)
     * Cope with potential backend slowness by imposing a timeout after
       which a new thread will (carefully!) fill in for a stuck one.
     * Generally allow non-integer timeouts, and reduce the default
       accept_timeout from 600 to 1, noting that it actually governs the
       frequency of housekeeping, including the new alarm checks.
     * Rework log metadata management to ensure proper request delimiting
       in all cases.

2010-12-22 11:57:11:
    Finalize version 1.3.1, with the following major changes relative to 1.3.0:
     * Allow cross-service sharing of DBAPI objects as appropriate.
     * Ensure that connection-pool cleanup occurs regularly rather than
       waiting indefinitely for idleness.
     * Support (trial) backends not known to the load balancer.
     * Log more information that may ease troubleshoooting.

2010-08-17 15:46:05:
    Finalize version 1.3.0, with the following major changes relative to 1.2.3:
     * Advance to 6.x stable components (dbase 6.1, otherwise 6.0),
       picking up various improvements in base libraries.
     * Support hard and soft limits on the number of client connections.
     * Generally improve timeout handling.
     * Improve backend selection; in particular, correct server
       preference logic and ensure pool diversity to limit the
       potential impact of bad backends.
     * Adapt to in-house CentOS systems, which lack the pidof utility
       (but still at least have pgrep).
     * Allow more threads (100, not just 10).

2009-12-28 15:46:36:
    Finalize version 1.2.3, with the following major changes relative to 1.2.2:
     * Support checking that LBSMD hasn't wrongly given up on any ports.
     * Keep track of empty "ping" requests, and log their counts periodically.
     * Correct handling of requests containing long (>= 128-byte) strings.

2009-06-03 10:50:46:
    Slip a belated infrastructure change into version 1.2.2 (binaries
    untouched):
     * Adjust LBSMD penalty-calculation feedback script to avoid barrages
       of notifications under some circumstances.

2009-05-22 10:51:07:
    Finalize version 1.2.2, with the following major changes relative to 1.2.1:
     * Pick up latest fixes to 4.0.0 stable components.
     * Fix a logic error that could lead to null pointer exceptions.
     * Try resetting the DB connection factory when it yields no backends,
       to compensate for overly persistent blacklisting.

2009-05-06 14:52:59:
    Slip belated infrastructure changes into version 1.2.1 (binaries untouched):
     * Track probe results and report appropriate penalties to LBSMD.
     * Have os_gateway.sh bomb out and send mail if /log/srv is unwritable.

2009-04-06 13:17:21:
    Finalize version 1.2.1, with the following major changes relative to 1.2.0:
     * Pick up latest fixes to 4.0.0 stable components.
     * Fix a logic error that could result in truncated responses when
       using the FreeTDS driver.
     * Ensure that exceptions that somehow slip through the cracks
       receive proper backtraces to help debug their causes.

2009-02-25 16:43:15:
    Put the final touches on what is to be version 1.2.0, with the following
    major changes relative to 1.1.1:
     * Switch to newer base libraries (the 4.0.0 components).
     * Support for the FreeTDS driver, now used by default.  (The commercial
       ctlib driver remains available by explicit request.)
     * Accommodation of transient backend errors.
     * More logging improvements (mainly streamlining).

2008-08-06 16:24:56:
    Finalized version 1.1.1, with the following major changes (taken from the
    trunk) relative to 1.1.0:
     * Better integration with TaskManager.
     * Further logging improvements.
     * No longer crashes when receiving certain malformatted requests.

2008-06-12 15:15:39.461659:
    Cloned from release 1.1.0

2008-05-06 14:55:19:
    Finalized version 1.1.0, with the following major changes (taken from the
    trunk) relative to 1.0.1:
     * Logging brought more closely in line with other apps (particularly CGIs).
     * Better recovery from backend errors.
     * Somewhat favors local backends for efficiency.
