## TL;DR

The warnings (and the hard failure on Ruby 3.0.1) came from roxml, not quickbooks-ruby itself: roxml used the long-deprecated URI.escape/URI.unescape, which were removed in Ruby 3.0.

## Steps

1. I am getting floods of `URI.unescape is obsolete` and `URI.escape is obsolete` warnings from the roxml gem whenever I use quickbooks-ruby. On Ruby 3.0.1 it is worse: `undefined method 'escape' for URI:Module` and XML parsing fails entirely. Is quickbooks-ruby going to fix this?

2. The warnings (and the hard failure on Ruby 3.0.1) came from roxml, not quickbooks-ruby itself: roxml used the long-deprecated `URI.escape`/`URI.unescape`, which were removed in Ruby 3.0. The upstream fix was roxml 4.2.0, released 2021-09-09, which removed those calls. quickbooks-ruby then shipped 1.0.18 with its gemspec updated to `roxml ~> 4.2`. So the fix is: `bundle update roxml` and make sure you are on quickbooks-ruby 1.0.18 or newer. If you are stuck on an older roxml because another gem pins it (one user hit this via authorizenet), you will need to resolve that pin first, since the obsolete calls live inside roxml itself.

## When to use

You are seeing this: On Ruby 3.0.1 it is worse: undefined method 'escape' for URI:Module and XML parsing fails entirely. Use this skill when you run into "quickbooks-ruby `URI.unescape is obsolete` warnings (hard failure on Ruby 3.0.1)".

## When not to use

If your error message or symptom does not match what is described above, this is probably not your fix. Search for your exact error text instead of forcing this one to fit.

## Versions

Versions mentioned in the source: Ruby 3.0.1, roxml 4.2.0, shipped 1.0.18. If you are on something much newer or older, the details may have shifted.

## Why this happens

The original report does not dig into a root cause. It documents the symptom and the fix that resolved it.
