SQLite is a software library that implements a self-contained, serverless, zero-configuration, transactional SQL database engine. SQLite is the most widely deployed SQL database engine in the world. The source code for SQLite is in the public domain.

What's New in This Release:

В· The SQLITE_CONFIG_PCACHE mechanism has been replaced with SQLITE_CONFIG_PCACHE2. If you do not know what this mechanism is (it is an extreme corner-case and is seldom used) then this change will not effect you in the least.

В· The default schema format number for new database files has changed from 1 to 4. SQLite has been able to generate and read database files using schema format 4 for six years. But up unto now, the default schema format has been 1 so that older versions of SQLite could read and write databases generated by newer versions of SQLite. But those older versions of SQLite have become so scarce now that it seems reasonable to make the new format the default.

В· SQLite is changing some of the assumptions it makes above the behavior of disk drives and flash memory devices during a sudden power loss. This change is completely transparent to applications. Read about the powersafe overwrite property for additional information.

Lots of new interfaces have been added in this release:

В· sqlite3_db_release_memory()
В· PRAGMA shrink_memory
В· sqlite3_db_filename()
В· sqlite3_stmt_busy()
В· sqlite3_uri_boolean()
В· sqlite3_uri_int64()

В· The PRAGMA cache_size statement has been enhanced. Formerly, you would use this statement to tell SQLite how many pages of the database files it should hold in its cache at once. The total memory requirement would depend on the database page size. Now, if you give PRAGMA cache_size a negative value -N, it will allocate roughly N kibibytes of memory to cache, divided up according to page size. This enhancement allows programs to more easily control their memory usage.

В· There have been several obscure bug fixes. One noteworthy bug, ticket ff5be73dee, could in theory result in a corrupt database file if a power loss occurred at just the wrong moment on an unusually cantankerous disk drive. But that is mostly a theoretical concern and is very unlikely to happen in practice. The bug was found during laboratory testing and has never been observed to occur in the wild.

System Requirements:

No special requirements.
Program Release Status: Minor Update
