Release notes
Release notes document what changed in each SAP release, new features, changes, and requirements, so you know what you can use, what you must adapt, and what may break. This hub covers the major product lines: ECC, S/4HANA, Fiori, HANA and NetWeaver.
Before any upgrade or when adopting new capability, release notes are essential reading: they tell you the new features to exploit, the behaviour changes and deprecations to plan around, and the compatibility requirements.

- ECC: the previous-generation ERP (enhancement packages).
- S/4HANA: the current suite (frequent feature releases).
- Watch out: Upgrading without reading the notes.
Why release notes matter
Before any upgrade or when adopting new capability, release notes are essential reading: they tell you the new features to exploit, the behaviour changes and deprecations to plan around, and the compatibility requirements. Ignoring them causes upgrade surprises and missed opportunities.
The product lines
- ECC: the previous-generation ERP (enhancement packages).
- S/4HANA: the current suite (frequent feature releases).
- Fiori: the UX (new/updated apps per release).
- HANA: the database (revisions/SPS).
- NetWeaver: the classic application-server platform.
How to use them
Before an upgrade, read the release notes for every version between your current and target release; note behaviour changes, deprecations (especially the S/4HANA simplification items), and compatibility requirements. Between upgrades, skim them for capabilities and security fixes worth adopting.
Common pitfalls
- Upgrading without reading the notes.
- Missing deprecations/simplification items.
- Overlooking compatibility changes.
