<li> Recognize TRUE and FALSE as constants.  (For compatibility, if there
     are columns named "true" or "false", then the identifiers refer to the
     columns rather than Boolean constants.)
<li> Support operators IS TRUE, IS FALSE, IS NOT TRUE, and IS NOT FALSE.
<li> Improve the omit-left-join optimization so that it works in cases where
     the right-hand table is UNIQUE but not necessarily NOT NULL.
<li> The "alternate-form-2" flag ("!") on the [built-in printf] implemention
     now causes string substitutions to measure the width and precision in
     characters instead of bytes.
<li> If the [xColumn] method in a [virtual table] implementation returns
     an error message using [sqlite3_result_error()] then give that error
     message preference over internally-generated messages.
<li> Bug fixes:
<ol type='a'>
  <li> Fix the parser to acceept valid [row value] syntax.
       Ticket [https://www.sqlite.org/src/info/7310e2fb3d046a5|7310e2fb3d046a5]
  <li> Fix the query planner so that it takes into account dependencies in
       the arguments to table-valued functions in subexpressions in 
       the WHERE clause.
       Ticket [https://www.sqlite.org/src/info/80177f0c226ff54|80177f0c226ff54]
  <li> Fix incorrect result with complex OR-connected WHERE and STAT4.
       Ticket [https://www.sqlite.org/src/info/ec32177c99ccac2|ec32177c99ccac2]
  <li> Fix potential corruption in [indexes on expressions] due to automatic
       datatype conversions.
       Ticket [https://www.sqlite.org/src/info/343634942dd54ab|343634942dd54ab]
  <li> Assertion fault in FTS4.
       Ticket [https://www.sqlite.org/src/info/d6ec09eccf68cfc|d6ec09eccf68cfc]
  <li> Incorrect result on the less-than operator in [row values].
       Ticket [https://www.sqlite.org/src/info/f484b65f3d62305|f484b65f3d62305]
  <li> Always interpret non-zero floating-point values as TRUE, even if
       the integer part is zero.
       Ticket [https://www.sqlite.org/src/info/36fae083b450e3a|36fae083b450e3a]
</ol>
<li> Additional fixes for issues detected by
     [https://github.com/google/oss-fuzz|OSSFuzz]:
<ol type='a'>
  <li> Fix a possible infinite loop on VACUUM for corrupt database files.
       Check-in [https://www.sqlite.org/src/info/27754b74ddf64|27754b74ddf64]
  <li> Disallow [parameters] in the [WITH clause] of triggers and views.
       Check-in [https://www.sqlite.org/src/info/b918d4b4e546d|b918d4b4e546d]
  <li> Fix a potential memory leak in [row value] processing.
       Check-in [https://www.sqlite.org/src/info/2df6bbf1b8ca8|2df6bbf1b8ca8]
  <li> Improve the performance of the [replace() SQL function] for cases where
       there are many substitutions on megabyte-sized strings, in an attempt
       to avoid OSSFuzz timeouts during testing.

<li> The output of [sqlite3_trace_v2()] now shows each individual SQL statement
     run within a trigger.
<li> Add the ability to read from [WAL mode] databases even if the application 
     lacks write permission on the database and its containing directory, as long as
     the -shm and -wal files exist in that directory.
