Pull request #1377 (2018-10-24 12:11:47)

 Increase the number of PBKDF2 iterations to 100000
The number has not been changed for more than 3 years.

I propose the same number as Django uses now - 100000.

davidism: Django increased it to 150000, so I'll update it to that, and add a changelog. https://github.com/django/django/commit/9792af3648b947ced235fa973a171ca74081a4d0

Add utils.invalidate_cached_property()
Sometimes you need to invalidate your cached properties. This makes it possible.

Added charset to HTTPException header content-type
Adds `charset=utf-8` to Header['Content-Type'] for HTTPException's response.

It looks like the template HTML body is in unicode, so we should set the charset explicitly so that Browsers will pick the correct one.

Pull request #1572 (2019-05-31 17:32:34)

fix: Parse Crosswalk UA as Android not ChromeOS (#1024)
In #1024, it was shown that when using the [Crosswalk Webview](crosswalk-project/crosswalk), the user agent parsing in Werkzeug would categorize `Crosswalk` as `ChromeOS` rather than `Android` although it was running on Android.

This occurred as we rely on matching `cros` anywhere in the UA string to determine if a UA is from `ChromeOS`. Upon reviewing `ChromeOS` [UA strings](http://www.webapps-online.com/online-tools/user-agent-strings/dv/operatingsystem52026/chrome-os), it became clear that `CrOS` is always surrounded by a space on either side. As such, this change makes us check for ` cros ` instead of `cros` and adds test coverage for this case.

It should be noted that on #1024, @alexpantyukhin proposes ensuring we check all strings as separate words (e.g. expecting a space on either side or the beginning or end of line). This may be reasonable but I'm unclear of how it might affect parsing other UA strings that aren't covered in the test cases.

Implements case-insensitive header equality
Currently this fails:

```python
assert datastructures.Headers({'X-Foo': 'fu'}) == datastructures.Headers({'x-foo': 'fu'})
```

The `Headers` class otherwise respects the case insensitivity of keys, this patch just extends this to the equality check.

markmcd: It looks like other tests are seeing these python3 failures too - let me know if there's something here I need to tweak to get them working.

Pull request #2349 (2022-03-15 21:51:04)

`safe_join` keeps `directory=""` as relative path
When using `send_from_directory`, which uses `safe_join`, if `directory=""` is given, it was discarded and the first untrusted path component could become the first component if it was a Windows drive-relative path.
