20 | | - |
21 | | -'Latest versions' refers to the latest stable version and the version immediately before that. |
22 | | - |
23 | | -We no longer support older versions of Internet Explorer. This is due to the very low and falling numbers that these browsers make up compared to our total visits. Read the blog post [Changing our testing requirements for Internet Explorer 8, 9 and 10](https://technology.blog.gov.uk/2018/06/26/changing-our-testing-requirements-for-internet-explorer-8-9-and-10/) by GOV.UK for more information on why we have done this. |

| 27 | +For 'compliant' browsers we aim to provide the same baseline experience. |
| 28 | + |
| 29 | +For 'necessary' browsers we aim to support optional enhancements as much as possible. However, we might sometimes need to adjust the component's behaviour, while still allowing the users to complete their task. This might include: |
| 30 | + |
| 31 | +- falling back to the no-JavaScript experience |
| 32 | +- disabling parts of the enhancement |
| 33 | +- doing a simpler alternative |
| 34 | + |
| 35 | +For 'limited' browsers we do not download or attempt to parse NHS.UK frontend’s JavaScript. We will not regularly test in these browsers. We will not fix bugs affecting these browsers. |
