The fixes included in this release are listed here. Currently only the english version
is available for download.

In IBM Domino 9.0.1 there´s also a new ODS format available – thanks a lot to
eknori for publishing this post, which can be accessed here:

Abstract from the blog entry from eknori:

9.0.1
The real solution is in 9.01 and requires that databases be upgraded to ODS52. Once a database is upgraded to ODS52, any database object can reside anywhere in the database (with the same boundary restrictions prior to the 9.0/8.53fp5 change).
Once a Notes Client or Domino Server has been upgraded to 9.0.1, set CREATE_R9_DATABASES=1 in notes.in and the next copy style compact of the database will upgrade the database to ODS52 and the encrypted databases will no longer be exposed to this very rare corruption.”

The following new features are included in 9.0.1:
