What's new in this version:
- Add support for PostgreSQL-style UPSERT
- Add support for auxiliary columns in r-tree tables
- Add C-language APIs for discovering SQL keywords used by SQLite: sqlite3_keyword_count(), sqlite3_keyword_name(), and sqlite3_keyword_check()
- Add C-language APIs for dynamic strings based on the sqlite3_str object
- Enhance ALTER TABLE so that it recognizes "true" and "false" as valid arguments to DEFAULT
- Add the sorter-reference optimization as a compile-time option. Only available if compiled with SQLITE_ENABLE_SORTER_REFERENCES
- Improve the format of the EXPLAIN QUERY PLAN raw output, so that it gives better information about the query plan and about the relationships between the various components of the plan
- Added the SQLITE_DBCONFIG_RESET_DATABASE option to the sqlite3_db_config() API
CLI Enhancements:
- Automatically intercepts the raw EXPLAIN QUERY PLAN output and reformats it into an ASCII-art graph
- Lines that begin with "#" and that are not in the middle of an SQL statement are interpreted as comments
- Added the --append option to the ".backup" command
- Added the ".dbconfig" command
Performance:
- UPDATE avoids writing database pages that do not actually change. For example, "UPDATE t1 SET x=25 WHERE y=?" becomes a no-op if the value in column x is already 25. Similarly, when doing UPDATE on records that span multiple pages, only write the subset of pages that contain the changed value(s)
- Queries that use ORDER BY and LIMIT now try to avoid computing rows that cannot possibly come in under the LIMIT. This can greatly improve performance of ORDER BY LIMIT queries, especially when the LIMIT is small relative to the number of unrestricted output rows
- The OR optimization is allowed to proceed even if the OR expression has also been converted into an IN expression. Uses of the OR optimization are now also more clearly shown in the EXPLAIN QUERY PLAN output
- The query planner is more aggressive about using automatic indexes for views and subqueries for which it is not possible to create a persistent index
- Make use of the one-pass UPDATE and DELETE query plans in the R-Tree extension where appropriate
- Performance improvements in the LEMON-generated parser
Bug fixes:
- For the right-hand table of a LEFT JOIN, compute the values of expressions directly rather than loading precomputed values out of an expression index as the expression index might not contain the correct value. Ticket 7fa8049685b50b5aeb0c2
- Do not attempt to use terms from the WHERE clause to enable indexed lookup of the right-hand table of a LEFT JOIN. Ticket 4ba5abf65c5b0f9a96a7a
- Fix a memory leak that can occur following a failure to open error in the CSV virtual table
- Fix a long-standing problem wherein a corrupt schema on the sqlite_sequence table used by AUTOINCREMENT can lead to a crash. Ticket d8dc2b3a58cd5dc2918a1
- Fix the json_each() function so that it returns valid results on its "fullkey" column when the input is a simple value rather than an array or object.
Hashes:
- SQLITE_SOURCE_ID: "2018-06-04 19:24:41 c7ee0833225bfd8c5ec2f9bf62b97c4e04d03bd9566366d5221ac8fb199a87ca"

What's new in this version:
- Add the sqlite3_serialize() and sqlite3_deserialize() interfaces when the SQLITE_ENABLE_DESERIALIZE compile-time option is used
- Recognize TRUE and FALSE as constants. (For compatibility, if there exist columns named "true" or "false", then the identifiers refer to the columns rather than Boolean constants)
- Support operators IS TRUE, IS FALSE, IS NOT TRUE, and IS NOT FALSE
- Added the SQLITE_DBSTATUS_CACHE_SPILL option to sqlite3_db_status() for reporting the number of cache spills that have occurred
- The "alternate-form-2" flag ("!") on the built-in printf implementation now causes string substitutions to measure the width and precision in characters instead of bytes
- 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
- Added the -A command-line option to the CLI to make it easier to manage SQLite Archive files
- Add support for INSERT OR REPLACE, INSERT OR IGNORE, and UPDATE OR REPLACE in the Zipfile virtual table
- Enhance the sqlite3changeset_apply() interface so that it is hardened against attacks from deliberately corrupted changeset objects
- Added the sqlite3_normalize() extension function
Query optimizer enhancements:
- Improve the omit-left-join optimization so that it works in cases where the right-hand table is UNIQUE but not necessarily NOT NULL
- Improve the push-down optimization so that it works for many LEFT JOINs
- Add the LEFT JOIN strength reduction optimization that converts a LEFT JOIN into an ordinary JOIN if there exist terms in the WHERE clause that would prevent the extra all-NULL row of the LEFT JOIN from appearing in the output set
- Avoid unnecessary writes to the sqlite_sequence table when an AUTOINCREMENT table is updated with an rowid that is less than the maximum
Bug fixes:
- Fix the parser to accept valid row value syntax
- Fix the query planner so that it takes into account dependencies in the arguments to table-valued functions in subexpressions in the WHERE clause
- Fix incorrect result with complex OR-connected WHERE and STAT4
- Fix potential corruption in indexes on expressions due to automatic datatype conversions
- Assertion fault in FTS4
- Incorrect result on the less-than operator in row values
- Always interpret non-zero floating-point values as TRUE, even if the integer part is zero
- Fix an issue in the fsdir(PATH) table-valued function to the fileio.c extension, that caused a segfault if the fsdir() table was used as the inner table of a join
- Issue an error rather instead of an assertion-fault or null-pointer dereference when the sqlite_master table is corrupted so that the sqlite_sequence table root page is really a btree-index page
- Fix the ANALYZE command so that it computes statistics on tables whose names begin with "sqlite"
Additional fixes for issues detected by OSSFuzz:
- Fix a possible infinite loop on VACUUM for corrupt database files
- Disallow parameters in the WITH clause of triggers and views
- Fix a potential memory leak in row value processing
- 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
- Provide an appropriate error message when the sqlite_master table contains a CREATE TABLE AS statement. Formerly this caused either an assertion fault or null pointer dereference. Problem found by OSSFuzz on the GDAL project
- Incorrect assert() statement removed
- Fix a problem with using the LIKE optimization on an INTEGER PRIMARY KEY

更新細節：
What's new in this version:
- The output of sqlite3_trace_v2() now shows each individual SQL statement run within a trigger
- 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
- Added the rtreecheck() scalar SQL function to the R-Tree extension
- Added the sqlite3_vtab_nochange() and sqlite3_value_nochange() interfaces to help virtual table implementations optimize UPDATE operations
- Added the sqlite3_vtab_collation() interface
- Added support for the "^" initial token syntax in FTS5
New extensions:
- The Zipfile virtual table can read and write a ZIP Archive
- Added the fsdir(PATH) table-valued function to the fileio.c extension, for listing the files in a directory
- The sqlite_btreeinfo eponymous virtual table for introspecting and estimating the sizes of the btrees in a database
- The Append VFS is a VFS shim that allows an SQLite database to be appended to some other file. This allows (for example) a database to be appended to an executable that then opens and reads the database
Query planner enhancements:
- The optimization that uses an index to quickly compute an aggregate min() or max() is extended to work with indexes on expressions
- The decision of whether to implement a FROM-clause subquery as a co-routine or using query flattening now considers whether the result set of the outer query is "complex" (if it contains functions or expression subqueries). A complex result set biases the decision toward the use of co-routines
- The planner avoids query plans that use indexes with unknown collating functions
- The planner omits unused LEFT JOINs even if they are not the right-most joins of a query
Other performance optimizations:
- A smaller and faster implementation of text to floating-point conversion subroutine: sqlite3AtoF()
- The Lemon parser generator creates a faster parser
- Use the strcspn() C-library routine to speed up the LIKE and GLOB operators
Improvements to the command-line shell:
- The ".schema" command shows the structure of virtual tables
- Added support for reading and writing SQL Archive files using the .archive command
- Added the experimental .expert command
- Added the ".eqp trigger" variant of the ".eqp" command
- Enhance the ".lint fkey-indexes" command so that it works with WITHOUT ROWID tables
- If the filename argument to the shell is a ZIP archive rather than an SQLite database, then the shell automatically opens that ZIP archive using the Zipfile virtual table
- Added the edit() SQL function
- Added the .excel command to simplify exporting database content to a spreadsheet
- Databases are opened using Append VFS when the --append flag is used on the command line or with the .open command
- Enhance the SQLITE_ENABLE_UPDATE_DELETE_LIMIT compile-time option so that it works for WITHOUT ROWID tables
- Provide the sqlite_offset(X) SQL function that returns the byte offset into the database file to the beginning of the record holding value X, when compiling with -DSQLITE_ENABLE_OFFSET_SQL_FUNC
Bug fixes:
- Infinite loop on an UPDATE that uses an OR operator in the WHERE clause. Problem introduced with 3.17.0 and reported on the mailing list about one year later
- Incorrect query results when the skip-ahead-distinct optimization is used
- Incorrect query results on a join with a ORDER BY DESC
- Inconsistent result set column names between CREATE TABLE AS and a simple SELECT
- Assertion fault when doing REPLACE on an index on an expression
- Assertion fault when doing an IN operator on a constant index
