+
+Thanks to the team and many contributors, we released v4.3.0 with many enhancements.
+
+Unfortunately, **there are some breaking changes, so please upgrade with caution**.
+Please read [ChangeLog](https://www.codeigniter.com/user_guide/changelogs/v4.3.0.html) and [Upgrading Guide](https://www.codeigniter.com/user_guide/installation/upgrade_430.html) carefully.
+
+**You must update spark file and a few Config files.**
+
+I hope most existing apps will not break unless you use your own classes that extend framework classes.
+
+And some of the default Config values in the Config files have changed, but existing apps will most likely not break unless you change the Config values by yourself.
+
+**This release contains over 50 enhancements.** A few things I want to highlight:
+
+- Query Builder supports `upsert()` and `upsertBatch()`, `deleteBatch()`, and now `*batch()` methods can set data from a query
+- Database Forge supports to add indexes in the existing tables and name indexes
+- "`spark route`" command enhancements
+- Improvement for CLI command testing
+- View Cells enhancements
+
+You can see the list of enhancements in [ChangeLog](https://www.codeigniter.com/user_guide/changelogs/v4.3.0.html#enhancements)
