Download Firebird 2.1 Release Notes

Changes to the Firebird API and ODS
“ODS Type” Recognition
N. Samofatov
Introduced a concept of ODS type to distinguish between InterBase and Firebird databases.
Smarter DSQL Error Reporting
C. Valderrama
The DSQL parser will now try to report the line and column number of an incomplete statement.
New Column in RDB$Index_Segments
D. Yemanov, A. Brinkman
A new column RDB$STATISTICS has been added to the system table RDB$INDEX_SEGMENTS to store the
per-segment selectivity values for multi-key indexes.
Note
The column of the same name in RDB$INDICES is kept for compatibility and still represents the total index
selectivity, that is used for a full index match.
