[Harry Potter] When did the wizarding world stop using new technology? Or alter alternatively: are they just way slower at adapting them?

The wizarding world (at least in Britain) *does* use some technology. They use the wheel they use the written word (both more than 3-4000 years old), they use glasses (ca. 13th century) and newspapers (16th century) but probably use magic instead of a printing press to produce them. They use steam trains (1800s). Their most "recent" architecture style also seems to suggest 19th century to me (e.g. in Diagon Alley).

Yes, Arthur Weasley has a flying car, but he is a Muggle artefact expert and admittedly a bit odd with regards to the average wizard.

So, the question remains: when did the wizarding world stop using new technology?

**EDIT:** sorry for the error in the title, I‘m typing on my phone.

They didn't really stop, but slowed their development considerably, likely because of whatever drove them to keep their secrecy from muggles. Without having a common element to drive their technological/magical development in that way, and the functions of most forms of technology reproducible by magic, it slowed down. However, some stuff does occasionally filter through, from either muggle-born mages, or from wizards seeing something neat, and wanting to replicate that in a way not possible with existing technology, and magic, which is why we occasionally see anachronistic objects like Colin's camera, Sirius' motorcycle, the Knight bus, and the Weasley's car.

Development of technology might also be stymied by traditionalist wizards like Lucius Malfoy,  or Dolores Umbridge, who prefer to keep to the old ways, rather than adapting inferior muggle technology, and soiling magic with it.
