The CI issue fixed

---

Parse-SDK-Flutter/Parse-SDK-Flutter/packages/flutter/CHANGELOG.md doesn't mention current version (4.0.0). Consider updating it with notes on this version prior to publication.

its now complaining about not mentioning the new 4.0.0 version in the CHANGELOG like the other release versions

• the dry-run expect something like this :

  3.1.4 (2023-03-01)

  Bug Fixes

  • Parse SDK internal database file parse.db is accessible for app user on iOS and may be accidentally deleted (#826)

• What is present in the CHANGELOG :

  Unreleased (master branch)

  BREAKING CHANGES

  • The source file name of the Flutter package has changed; to import the Flutter package use parse_server_sdk_flutter.dart instead of parse_server_sdk.dart (#846)

  Features

  • Rename Flutter package source file to parse_server_sdk_flutter.dart (#846)

[mtrezza]

Is it just looking for the string 4.0.0? Could you try changing the changelog line to 4.0.0 (unreleased)

[Nidal-Bakir]

Yes, that will make it happy. should I revert the last commit and open a new PR to fix this?

this (4.0.0) Unreleased or (4.0.0) Unreleased both will work

[mtrezza]

I think this is good now
