Subject:      2006AA Release Files Reissued

Dear UMLS Users:
On Feb. 13 the NLM determined that the 2006AA UMLS release contained MeSH 
data errors in four Metathesaurus files.  The release was recalled, 
stopping all download of the incorrect files. Users who had downloaded the 
release were contacted individually.  

A corrected and complete UMLS release is now available for download on the 
UMLSKS.  All 2006AA UMLS DVDs will contain the corrected files, and will be 
sent to those who have requested them in March.  An extensive QA process 
has been implemented to ensure that the problem does not reoccur in future 
releases.  

An error was also discovered relating to hierarchies that include 
references to excluded strings when users exclude UTF-8 characters from 
their subsets.  A release note with a solution has been posted on the UMLS 
Web.

We sincerely apologize for these errors and the delays they caused.  We 
will continue to update the UMLS Release Notes with any other release 
issues. 

Thank You, 

Rachel Kleinsorge
