django-upgrade VS semver

30% of Django developers upgrade every LTS release[1]. As Django 3.2 runs out of support in April this year[2], it's worth celebrating Adam Johnson's package django-upgrade (https://github.com/adamchainz/django-upgrade) which has a set of fixers to automatically update your Django code to the version of your choice.

Curious if anyone has used 2to3 (https://docs.python.org/3/library/2to3.html) for upgrading Python code and can share their experience with it? Would you recommend?

I had easy and quick upgrade from 3.2 to 4.1 using django-upgrade package. Project was pretty big, and I didn’t expect to be that easy to migrate to 4.1.

Regarding the actual Django upgrade you might want to take a look at Django Upgrade https://github.com/adamchainz/django-upgrade - a tool to automate some of the boring tedious stuff in an upgrade.

Running https://github.com/adamchainz/django-upgrade with https://github.com/asottile/pyupgrade recursively will give an idea about how much work is there on Django side. Still, there may have dependency on third party libraries (both django+python). Another thing to consider is which role Django performing here, serving APIs or html views. As good test coverage is already there, you are on lucky side.

I recently upgraded one of my project to Django v4, from Django v1. The changes from Django 3 to 4 were fairly simple, just one line change in my case. The change log is extremely detailed, it was easy to upgrade. Also, I found a tool called django-upgrade which makes some changes automatically, rest I made manually.

Adam Johnson has written a nifty tool (https://github.com/adamchainz/django-upgrade) that can automatically do this for you. Even if you don't want to use the tool, the README generally outlines all the key issues you need to be aware of.

You should try the new [django-upgrade](https://github.com/adamchainz/django-upgrade) package. It claims you can either just run it or hook it into your CI. It will automatically take care of some of the heavy lifting for you.

We increase the version of our product as specified in SemVer and deploy it to production, preferably following good deployment practices to have no downtime.

Using Conventional Commits ⭐ as a standard for your commit messages, makes Semantic Versioning 🔖 as easy as can be, with tools like Conventional Changelog 📄 Standard Version 🔖 and Semantic Release 📦🚀

Semantic Versioning: for every update (major, minor, or patch) made, increment the version number according to semantic versioning.

npm automates the process of installing, updating, and managing dependencies, which helps to avoid "dependency hell." It supports semantic versioning (semver) that automatically handles patch and minor updates without breaking the existing code, thus maintaining stability across projects. npm also provides the capability to run scripts and commands defined in package.json, which can automate common tasks such as testing, building, and deployment.

We are pleased to introduce Semantic Versioning and release channels to Snyk CLI from v.1.1291.0 onwards. In this blog post, we will share why we are introducing these changes, what problems these changes solve for our customers, and how our customers can opt-in according to their needs.

Following the Semantic Versioning rules, you should raise the version number every time you need to publish your library. In your "package.json" file, you need to change the version number to reflect whether the changes are major, minor, or patch updates.

Semantic Versioning: An established convention for version numbers following the pattern MAJOR.MINOR.PATCH

Increases the major of the latest tag and prints it As per the Semver spec, it'll also clear the pre-release…

The reason for this is that software libraries and package managers, in general, but specifically here, rely on semantic versioning. Semantic versioning is really useful for distributing packages in a predictable way. What does this look like for our project?
