At my last job, we only updated dependencies when there was a compelling reason. It was awful.

What would happen from time to time was that an important reason did come up, but the team was now many releases behind. Whoever was unlucky enough to sign up for the project that needed the updated dependency now had to do all those updates of the dependency, including figuring out how they affected a bunch of software that they weren't otherwise going to work on. (e.g., for one code path, I need a bugfix that was shipped three years ago, but pulling that into my component affects many other code paths.) They now had to go figure out what would break, figure out how to test it, etc. Besides being awful for them, it creates bad incentives (don't sign up for those projects; put in hacks to avoid having to do the update), and it's also just plain bad for the business because it means almost any project, however simple it seems, might wind up running into this pit.

I now think of it this way: either you're on the dependency's release train or you jump off. If you're on the train, you may as well stay pretty up to date. It doesn't need to be every release the minute it comes out, but nor should it be "I'll skip months of work and several major releases until something important comes out". So if you decline to update to a particular release, you've got to ask: am I jumping off forever, or am I just deferring work? If you think you're just deferring the decision until you know if there's a release worth updating to, you're really rolling the dice.

(edit: The above experience was in Node.js. Every change in a dynamically typed language introduces a lot of risk. I'm now on a team that uses Rust, where knowing that the program compiles and passes all tests gives us a lot of confidence in the update. So although there's a lot of noise with regular dependency updates, it's not actually that much work.)

I fought off the local imposition of Dependabot by executive fiat about a year ago by pointing out that it maximizes vulnerabilities to supply chain attacks if blindly followed or used as a metric excessively stupidly. Maximizing vulnerabilities was not the goal, after all. You do not want to harass teams with the fact that DeeplyNestedDepen just went from 1.1.54-rc2 to 1.1.54-rc3 because the worst case is that they upgrade just to shut the bot up.

I think I wouldn't object to "Dependabot on a 2-week delay" as something that at least flags. However working in Go more than anything else it was often the case even so that dependency alerts were just an annoyance if they aren't tied to a security issue or something. Dynamic languages and static languages do not have the same risk profiles at all. The idea that some people have that all dependencies are super vital to update all the time and the casual expectation of a constant stream of vital security updates is not a general characteristic of programming, it is a specific characteristic not just of certain languages but arguably the community attached to those languages.

(What we really need is capabilities, even at a very gross level, so we can all notice that the supposed vector math library suddenly at version 1.43.2 wants to add network access, disk reading, command execution, and cryptography to the set of things it wants to do, which would raise all sorts of eyebrows immediately, even perhaps in an automated fashion. But that's a separate discussion.)

Thats because the security industry has been captured by useless middle manager types who can see that "one dependency has a critical vulnerability", but could never in their life scrounge together the clue to analyze the impact of that vulnerability correctly. All they know is the checklist fails, and the checklist can not fail.

(Literally at one place we built a SPA frontend that was embedded in the device firmware as a static bundle, served to the client and would then talk to a small API server. And because these NodeJS types liked to have libraries reused for server and frontend, we would get endless "vulnerability reports" - but all of this stuff only ever ran in the clients browser!)

You could use this funky tool from oss-rebuild which proxies registries so they return the state they were at a past date: https://github.com/google/oss-rebuild/tree/main/cmd/timewarp

that's generally true, no?

of course waiting a few days/weeks should be the minimum unless there's a CVE (or equivalent) that's applies

I once almost managed to get back on the release train. I was tasked with adding new features to a piece of software originally developed years ago for internal use at a university. It was running PHP 5 on Debian Jessie. The first hurdle was that no Docker image existed for the production environment (PHP 5). After patching all the code and getting it to run on PHP 8, another issue surfaced: the MSSQL server it needed to communicate with only supported TLS 1.0, which had been removed from the OpenSSL version included in Debian 12—the base image for my PHP 8 setup.

In the end, I decided to implement a lightweight PHP 5 relay to translate SQL requests so the MSSQL server could still be accessed. The university stuffs were quite satisfied with my work. But I really felt guilty for the next guy who will touch this setup. So I still didn’t quite make it back onto the release train… as that PHP 5 relay counts.

Jumping straight to the new release because it fixed one security bug has always struck me as a round about way of trying to achieve security through obscurity, especially when the releases include tons of other changes. Yes, this release fixed CVE-123, but how many new ones were added?

> Sadly, not enough tooling seems to take this into account

Most tooling (e.g. Dependabot) allows you to set an interval between version checks. What more could be done on that front exactly? Devs can already choose to check less frequently.
