SQLite Release 3.43.1 On 2023-09-11
Prior changes from version 3.43.0 (2023-08-24):
-  Add support for Contentless-Delete FTS5 Indexes.  This is a variety
     of FTS5 full-text search index that omits storing the content that is being indexed
     while also allowing records to be deleted.
-  Enhancements to the date and time functions:
  
  -  Added new time shift modifiers of the form ±YYYY-MM-DD HH:MM:SS.SSS.
  
-  Added the timediff() SQL function.
  
 
-  Added the octet_length(X) SQL function.
-  Added the sqlite3_stmt_explain() API.
-  Query planner enhancements:
  
  -  Generalize the LEFT JOIN strength reduction optimization so that it works
       for RIGHT and FULL JOINs as well.  Rename it to
       OUTER JOIN strength reduction.
  
-  Enhance the theorem prover in the OUTER JOIN strength reduction optimization
       so that it returns fewer false-negatives.
  
 
-  Enhancements to the decimal extension:
  
  -  New function decimal_pow2(N) returns the N-th power of 2 for integer N
       between -20000 and +20000.
  
-  New function decimal_exp(X) works like decimal(X) except that it returns
       the result in exponential notation - with a "e+NN" at the end.
  
-  If X is a floating-point value, then the decimal(X) function now does a full
       expansion of that value into its exact decimal equivalent.
  
 
-  Performance enhancements to JSON processing results in a 2x performance
     improvement for some kinds of processing on large JSON strings.
-  New makefile target "verify-source" checks to ensure that there are no
     unintentional changes in the source tree.  (Works for 
     canonical source code only - 
     not for precompiled amalgamation tarballs.)
-  Added the SQLITE_USE_SEH compile-time option that enables Structured
     Exception Handling on Windows while working with the memory-mapped
     shm file that is part of WAL mode processing.  This option is enabled
     by default when building on Windows using Makefile.msc.
-  The VFS for unix now assumes that the nanosleep() system call is
     available unless compiled with -DHAVE_NANOSLEEP=0.
Changes in this specific patch release, version 3.43.1 (2023-09-11):
-  Fix a regression in the way that the sum(), avg(), and total()
     aggregate functions handle infinities.
-  Fix a bug in the json_array_length() function that occurs when the
     argument comes directly from json_remove().
-  Fix the omit-unused-subquery-columns optimization (introduced in
     in version 3.42.0) so that it works correctly if the subquery is a
     compound where one arm is DISTINCT and the other is not.
-  Other minor fixes.
