<h2>SQLite Release 3.8.0.2 On 2013-09-03</h2><p><ol class='lessindent'>
<li>Add support for <a href="../partialindex.html">partial indexes</a></li>
<li>Cut-over to the <a href="../queryplanner-ng.html">next generation query planner</a> for faster and better query plans.
<li>The <a href="../eqp.html">EXPLAIN QUERY PLAN</a> output no longer shows an estimate of the number of
rows generated by each loop in a join.
<li>Added the <a href="../fts3.html#fts4notindexed">FTS4 notindexed option</a>, allowing non-indexed columns in an FTS4 table.
<li>Added the <a href="../c3ref/c_stmtstatus_counter.html#sqlitestmtstatusvmstep">SQLITE_STMTSTATUS_VM_STEP</a> option to <a href="../c3ref/stmt_status.html">sqlite3_stmt_status()</a>.
<li>Added the <a href="../pragma.html#pragma_cache_spill">cache_spill pragma</a>.
<li>Added the <a href="../pragma.html#pragma_query_only">query_only pragma</a>.
<li>Added the <a href="../pragma.html#pragma_defer_foreign_keys">defer_foreign_keys pragma</a> and the
<a href="../c3ref/db_status.html">sqlite3_db_status</a>(db, <a href="../c3ref/c_dbstatus_options.html#sqlitedbstatusdeferredfks">SQLITE_DBSTATUS_DEFERRED_FKS</a>,...) C-language interface.
<li>Added the "percentile()" function as a <a href="../loadext.html">loadable extension</a> in the ext/misc
subdirectory of the source tree.
<li>Added the <a href="../compile.html#allow_uri_authority">SQLITE_ALLOW_URI_AUTHORITY</a> compile-time option.
<li>Add the <a href="../c3ref/cancel_auto_extension.html">sqlite3_cancel_auto_extension(X)</a> 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 <a href="../compile.html#default_automatic_index">SQLITE_DEFAULT_AUTOMATIC_INDEX</a> compile-time option. Setting this option
to 0 disables automatic indices by default.
<li>Issue an <a href="../rescode.html#warning_autoindex">SQLITE_WARNING_AUTOINDEX</a> warning on the <a href="../c3ref/c_config_covering_index_scan.html#sqliteconfiglog">SQLITE_CONFIG_LOG</a> whenever
the query planner uses an automatic index.
<li>Added the <a href="../compile.html#fts3_max_expr_depth">SQLITE_FTS3_MAX_EXPR_DEPTH</a> compile-time option.
<li>Added an optional 5th parameter defining the collating sequence to the
next_char() extension SQL function.
<li>The <a href="../rescode.html#busy_snapshot">SQLITE_BUSY_SNAPSHOT</a> 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 <a href="../appfunc.html">application-defined SQL functions</a> 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 <a href="../cli.html">command-line shell</a> 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 <a href="../fts3.html#unicode61">unicode61</a> tokenizer of <a href="../fts3.html#fts4">FTS4</a>, 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 <a href="../queryplanner-ng.html">NGQP</a>.
</ol></p><p><ol class='lessindent'>
<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.
</ol></p><p><ol class='lessindent'>
<li>Fix a bug in the optimization that attempts to omit unused LEFT JOINs
<li>SQLITE_SOURCE_ID:
"2013-09-03 17:11:13 7dd4968f235d6e1ca9547cda9cf3bd570e1609ef"
<li>SHA1 for sqlite3.c: 6cf0c7b46975a87a0dc3fba69c229a7de61b0c21
