Upgrade Gotchas for 3.0.0
First, see [http://spamassassin.apache.org/full/3.0.x/dist/UPGRADE the UPGRADE file] from the distribution for the basic gotchas.
SpamAssassin 3.0.0 has a significantly different API (Application Program Interface) from the 2.x series of code. This means that if you use SpamAssassin through a third-party utility (milter, etc,) you need to make sure you have an updated version which supports 3.0.0, such as:
- Configuration settings that include the word "hits" have generally been renamed to use the word "score" instead, for consistency.
- If you were using always_add_report 1, you now need to put this in your config: add_header all Report _REPORT_
- If you don't want bayes to auto learn, you now need to use "bayes_auto_learn 0" instead of "auto_learn 0"
