The bullet points:
1) Multi-year contracts are cancelable after 3 years even if the contract runs longer.
(nonetheless you should always always always insist on yearly cancellability, otherwise just don't sign)
2) You now have the right to revoke your signature during the first 14 days.
3) You now have five years to make a claim (only two years so far). This may be of particular relevance for top-up health insurance, where treatment often goes on for many years.
4) Used to be: Top-up health insurances can be canceled by both parties if a claim needs to be paid for. Starting next year only the patient has that right, so the insurance can no longer give notice just because a contract gets too costly for them.
5) Giving notice by email will become valid. So far you had to use snail-mail with a traditional signature.
6) The damaged party will be able to directly place a claim with the culprit's insurance. Up until now, if the culprit drags their feet and doesn't do that, the damaged party has to wait and wait and wait. Often that would mean paying for the repairs themselves, those days will be over soon thanks to the change.
