indexes), and

.
InnoDB
storage engine is now offered as a standard feature of the
MySQL
server. This means full support for ACID transactions, foreign
keys with cascading UPDATE

, and row-level locking
are now standard features.
See section InnoDB

FULLTEXT
search properties of MySQL Server 4.0 enables
FULLTEXT
indexing of large text masses with both binary
and natural-language searching logic. You can customize minimal word
length and define your own stop word lists in any human language,
enabling a new set of applications to be built with MySQL Server.

statement, a long-awaited standard SQL feature.
TRUNCATE TABLE

supports a new character set, latin1_de

German sorting order sorts words with umlauts in the same order
as do German telephone books.
mysqld
parameters (startup options) can now be set without taking
down the server. This is a convenient feature for database administrators
(DBAs).
See section SET OPTION
.
DELETE
and UPDATE
statements have been added..
MyISAM
storage engine now supports symbolic
linking at the table level (and not just the database level as before).
SQL_CALC_FOUND_ROWS
and FOUND_ROWS()
are new functions that make it
possible to find out the number of rows a SELECT
query that includes a
LIMIT
clause would have returned without that clause.
The news section of this manual includes a more in-depth list of features. See section C.3 Changes in release 4.0.x (Production).
