DISQLite3 v. 1.5.2 has been released and is available for download:

  http://www.yunqa.de/delphi/doku.php/products/sqlite3/

DISQLite3 implements a self-contained, embeddable, zero-configuration SQL 
database engine for Borland / CodeGear Delphi.

Features include:

* ACID transactions, even after system crashes and power failures.
* Zero-configuration ­ no setup or administration needed.
* Implements most of SQL-92.
* A complete database is stored in a single disk file.
* Supports terabyte-sized databases and gigabyte-sized strings and blobs.
* Self-contained: no external dependencies, no DLLs.
* Small footprint: less than 300 KB code space only.
* Full Text Search with customizable tokenizer and prefix matching.
* Database AES encryption with SHA256 key generator.
* Db.pas is not required, which allows DISQLite3 to compile with all flavours 
of Delphi, including Delphi Standard and Delphi Personal.
* Faster than popular database engines for most common operations.
* Simple, easy to use API.
* Database files created with DISQLite3 can also be accessed by Linux and MacOS 
using the SQLite3 libraries.

List of changes since the last release:

* Always open files using FILE_FLAG_RANDOM_ACCESS under windows.
* The 3rd parameter of the built-in SUBSTR() function is now optional.
* Bug fix: do not invoke the authorizer when reparsing the schema after a 
schema change.
* Virtual machine stores 64-bit integer and floating point constants in binary 
instead of text for a performance boost.
* Add the NEAR/x operator to FTS3.
* Handle "IS NULL" constraints on virtual table scans. IS NULL constraints are 
not passed to the virtual table layer.
* Fix some minor problems with malloc failure and in-memory databases.
* New DISQLite3ZLib.pas unit which implements the SQL functions COMPRESS() and 
UNCOMPRESS().
