(edit) release, flexviews, flexcdc
I am happy to announce the GA release of Flexviews. I've numbered the release 1.7.0 GA.
There are a small number of bug fixes and enhancements:

  • Fixes for views which have aggregate functions but no GROUP BY expressions could have had problems during incremental update.
  • GA support for all aggregate functions except GROUP_CONCAT and AVG(distinct).
  • The PERCENTILE_XX (ie PERCENTILE_90 for a 90th percentile calculation) is now stable too


FlexCDC got a number of fixes and improvements:

  • TIMESTAMP columns are now properly supported
  • Now mysqlbinlog errors are detected, and the program exits gracefully
  • FlexCDC now logs to a log file instead of writing to STDOUT/STDERR
  • There are new PHP scripts for adding and removing table changelogs
  • Also, a new wrapper script (consumer_safe.sh)

Whats new in Flexviews 1.6.0RC1
  • This is the first release candidate before the final release.  If no major bugs are uncovered, then the next release will be the first GA release. 
  • Flexviews now has a test suite for all major features.  The creation of these tests uncovered a number of issues which have been resolved in this release. 
  • All MySQL aggregate functions except GROUP_CONCAT are now supported. 
  • A special aggregate function called PERCENTILE is now also supported.  The calculation uses a modified version of the GROUP_CONCAT based solution suggested by Roland Bouman for percentiles.  This function should be considered experimental.  Please report bugs if you find any.
  • You can add indexes to enabled materialized views using SQL_API/add_expr
  • Adding PRIMARY KEY indexes is no longer
