Instead of complexe tracking throught the context
just track change and process the message at the end
using the precommit feature (the message are posted
just before commiting)
- track m2m simplify using native mail_thread and process them like text
- simplify code for track one2many
- avoid useless code on model not impacted by the tracking
For example on the product if you open the 'stock.putaway.rule'
you have activated the tracking on putaway_rule_ids
change on rule should be posted on the related product
