Jul 2015-SP4 bugfix release

MonetDB Common

  • Fixed a bug that caused various instances where old data returned or where crashes occurred. The problem was that internally data wasn’t always marked dirty when it was being changed, causing later processing to not deal with the changed data correctly.

Bug Fixes

  • 3905: MonetDB doesn’t handle ANY/SOME/ALL operator correctly
  • 3929: R aggregate not recognized when using 3 or more parameters
  • 3965: Not possible to quote/escape single quote character in the name of the file to load.
  • 3968: Missing double use of column names

Jul 2015-SP3 bugfix release

Jul 2015 feature release

Do not skip upgrades!

  • One of the new features in this release is the possibility to use “best effort” when importing CSV files into the server.  However, we have found a bug that causes this feature to misbehave when the CSV file cannot be read correctly (exactly when one might want to use best effort).  Hence we recommend to not use the feature.  See bug 3797Z.
