-## 2.3.0 - UNRELEASED
+### Upcoming Breaking Change
+- Starting in 2.5.0, chainlink nodes will no longer allow insecure configuration for production builds. Any TOML configuration that sets the following line will fail validation checks in `node start` or `node validate`:
+```
+AllowSimplePasswords=true
+```
+- To migrate on production builds, update the database password set in Database.URL to be 16 - 50 characters without leading or trailing whitespace. URI parsing rules apply to the chosen password - refer to RFC 3986 for special character escape rules.

 ### Added
 - Add a new field called `Order` (range from 1 to 100) to `EVM.Nodes` that is used for the `PriorityLevel` node selector and also as a tie-breaker for `HighestHead` and `TotalDifficulty`. `Order` levels are considered in ascending order. If not defined it will default to `Order = 100` (last level).
