chng {2013-08-29 (3.8.0.1)} {
<li>Add support for [partial indexes]</li>
<li>Cut-over to the [next generation query planner] for faster and better query plans.
<li>The [EXPLAIN QUERY PLAN] output no longer shows an estimate of the number of 
    rows generated by each loop in a join.
<li>Added the [FTS4 notindexed option], allowing non-indexed columns in an FTS4 table.
<li>Added the [SQLITE_STMTSTATUS_VM_STEP] option to [sqlite3_stmt_status()].
<li>Added the [cache_spill pragma].
<li>Added the [query_only pragma].
<li>Added the [defer_foreign_keys pragma] and the
    [sqlite3_db_status](db, [SQLITE_DBSTATUS_DEFERRED_FKS],...) C-language interface.
<li>Added the "percentile()" function as a [loadable extension] in the ext/misc
    subdirectory of the source tree.
<li>Added the [SQLITE_ALLOW_URI_AUTHORITY] compile-time option.
<li>Add the [sqlite3_cancel_auto_extension(X)] interface.
<li>A running SELECT statement that lacks a FROM clause (or any other statement that
    never reads or writes from any database file) will not prevent a read
    transaction from closing.
<li>Add the [SQLITE_DEFAULT_AUTOMATIC_INDEX] compile-time option.  Setting this option
    to 0 disables automatic indices by default.
<li>Issue an [SQLITE_WARNING_AUTOINDEX] warning on the [SQLITE_CONFIG_LOG] whenever
    the query planner uses an automatic index.
<li>Added the [SQLITE_FTS3_MAX_EXPR_DEPTH] compile-time option.
<li>Added an optional 5th parameter defining the collating sequence to the 
    next_char() extension SQL function.
<li>The [SQLITE_BUSY_SNAPSHOT] extended error code is returned in WAL mode when
    a read transaction cannot be upgraded to a write transaction because the read is
    on an older snapshot.
<li>Enhancements to the sqlite3_analyzer utility program to provide size
    information separately for each individual index of a table, in addition to
    the aggregate size.
<li>Allow read transactions to be freely opened and closed by SQL statements run 
    from within the implementation of [application-defined SQL functions] if the
    function is called by a SELECT statement that does not access any database table.
<li>Disable the use of posix_fallocate() on all (unix) systems unless the
    HAVE_POSIX_FALLOCATE compile-time option is used.
<li>Update the ".import" command in the [command-line shell] to support multi-line
    fields and correct RFC-4180 quoting and to issue warning and/or error messages
    if the input text is not strictly RFC-4180 compliant.
<li>Bug fix: In the [unicode61] tokenizer of [FTS4], treat all private code points
    as identifier symbols.
<li>Bug fix: Bare identifiers in ORDER BY clauses bind more tightly to output column
    names, but identifiers in expressions bind more tightly to input column names.
    Identifiers in GROUP BY clauses always prefer output column names, however.
<li>Bug fixes: Multiple problems in the legacy query optimizer were fixed by the 
    move to [NGQP].
</ul><p>The above are changes since [version 3.7.17].  The differences
between 3.8.0 and 3.8.0.1 are as follows:</p><ul>
<li>Fix an off-by-one error that caused quoted empty string at the end of a 
CRNL-terminated line of CSV input to be misread by the command-line shell.
<li>Fix a query planner bug involving a LEFT JOIN with a BETWEEN or LIKE/GLOB
constraint and then another INNER JOIN to the right that involves an OR constraint.
<li>Fix a query planner bug that could result in a segfault when querying tables
with a UNIQUE or PRIMARY KEY constraint with more than four columns.

chng {2013-03-29 (3.7.16.1)} {
<li>Fix for a bug in the ORDER BY optimizer that was introduced in
    [version 3.7.15] which would sometimes optimize out the sorting step
    when in fact the sort was required.
    Ticket [http://www.sqlite.org/src/info/a179fe7465 | a179fe7465]
<li>Fix a long-standing bug in the [CAST expression] that would recognize UTF16

    Ticket [http://www.sqlite.org/src/info/6bfb98dfc0c | 6bfb98dfc0c].
<li>The SQLITE_OMIT_MERGE_SORT option has been removed.  The merge sorter is
    now a required component of SQLite.
<li>Fixed lots of spelling errors in the source-code comments
<li>SQLITE_SOURCE_ID:

}

chng {2013-03-18 (3.7.16)} {
<li>Added the [PRAGMA foreign_key_check] command.
<li>Added new extended error codes for all SQLITE_CONSTRAINT errors
<li>Added the SQLITE_READONLY_ROLLBACK extended error code for when a database
    cannot be opened because it needs rollback recovery but is read-only.
<li>Added SQL functions [unicode(A)] and [char(X1,...,XN)].
