According to this page I tried to upgrade my CakePHP version to 4.5:
Running composer require --update-with-dependencies "cakephp/cakephp:^4.5" results in:

Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.

Installation failed, reverting ./composer.json and ./composer.lock to their original content.

OK, trying this
composer require --with-all-dependencies "cakephp/cakephp:^4.5"

results in

./composer.json has been created
Running composer update cakephp/cakephp --with-all-dependencies

Installation failed, deleting ./composer.json.

I would like to upgrade to 4.5 so I can remove all deprecation messages, so I am prepared for CakePHP 5. How can I upgrade, what I have to modify?

Change your minimum stability?

CakePHP 4.5 is not released yet, only CakePHP 5.0
We have a RC1 for it though but you need to adjust your composer.json to

"cakephp/cakephp": "4.5.0-RC1",

and add

    "minimum-stability": "dev",
    "prefer-stable": true

to allow dev packages to be installed as well.

The do a composer update -W and it should install

OK Kevin. I must have missed that CakePHP 4.5 is not released yet in the link I mentioned in my 1st post.
The question is, if it’s a good idea to use the RC1 in a production environment. Usually not, so I think I should wait until 4.5 has been officially released. Do you agree?

Thank you

Well I have used the current state of 4.next for the past 2 months and had no problems.

But still this is up 2 you if you want to do that. But you still have more then enough time to upgrade to 4.5 or 5.0 so I would just wait till 4.5 is out, update to that and fix all deprecations and then go to 5.0
