We are pleased to announce the new Sedna release!
Sedna 3.3 binaries and sources are immediately available at:
http://modis.ispras.ru/sedna/download or
http://sourceforge.net/projects/sedna/files .
*Significant Changes and New Features:*
- Query Explain Statement [2]: shows execution plan of the XQuery or
update statement.
- Query Profile Statement [3]: profiles XQuery or update statement, shows
execution time, number of calls for each physical operation in the execution
plan.
- Improved Errors Diagnostic: Sedna now reports details of XQuery/XUpdate
execution errors with both line and column numbers in the source query code.
- Version 4 of the Client/Server Protocol: each query result item
contains XQuery Data Model type [4].
- Completely C/C++ source code: Sedna now doesn't contain sources in
Schema!
*
Other Changes:
*
- Metadata system document '$modules' removed. Use collection '$modules'
instead to get names of all modules.
- We do not have resources to deliver Mac OS (Darwin) PowerPC binary
releases and night builds. However, we will be very glad if someone has
ability to create Darwin's PPC build.
- As usual, Sedna 3.3 build includes a lot of bug fixes, improvements and
optimizations.
*
