SQLite Release 3.25.0 On 2018-09-15
-  Add support for window functions
-  Enhancements the ALTER TABLE command:
  -  Add support for renaming columns within a table using
       ALTER TABLE table RENAME COLUMN oldname TO newname.
  
-  Fix table rename feature so that it also updates references
       to the renamed table in triggers and views.
 
-  Query optimizer improvements:
  -  Avoid unnecessary loads of columns in an aggregate query that
       are not within an aggregate function and that are not part
       of the GROUP BY clause.
  
-  The IN-early-out optimization: When doing a look-up on a
       multi-column index and an IN operator is used on a column
       other than the left-most column, then if no rows match against
       the first IN value, check to make sure there exist rows that
       match the columns to the right before continuing with the
       next IN value.
  
-  Use the transitive property to try to propagate constant
       values within the WHERE clause.  For example, convert
       "a=99 AND b=a" into "a=99 AND b=99".
 
-  Use a separate mutex on every inode in the unix VFS, rather than
     a single mutex shared among them all, for slightly better concurrency
     in multi-threaded environments.
-  Enhance the PRAGMA integrity_check command for improved detection
     of problems on the page freelist.
-  Output infinity as 1e999 in the ".dump" command of the
     command-line shell.
-  Added the SQLITE_FCNTL_DATA_VERSION file-control.
-  Added the Geopoly module
Bug fixes:
 
-  The ORDER BY LIMIT optimization might have caused an infinite loop
     in the byte code of the prepared statement under very obscure
     circumstances,
     due to a confluence of minor defects in the query optimizer.
     Fix for ticket
     9936b2fa443fec03ff25
-  On an UPSERT when the order of constraint checks is rearranged,
     ensure that the affinity transformations on the inserted content
     occur before any of the constraint checks. Fix for ticket
     79cad5e4b2e219dd197242e9e.
-  Avoid using a prepared statement for ".stats on" command of the
     CLI after it has been closed by the ".eqp full" logicc. Fix for ticket
     7be932dfa60a8a6b3b26bcf76.
-  The LIKE optimization was generating incorrect byte-code and hence
     getting the wrong answer
     if the left-hand operand has numeric affinity and the right-hand-side
     pattern is '/%' or if the pattern begins with the ESCAPE character.
