## Version 5.1.0

_2025-07-07_

 *  New: `Response.peekTrailers()`. When we changed `Response.trailers()` to block instead of
    throwing in 5.0.0, we inadvertently removed the ability for callers to peek the trailers
    (by catching the `IllegalStateException` if they weren't available). This new API restores that
    capability.

But let's save you the time of reading the full long specification just to find those little pieces of information you need.

Let's use the tools provided by **FastAPI** to handle security.

## How it looks { #how-it-looks }

Let's first just use the code and see how it works, and then we'll come back to understand what's happening.

## Create `main.py` { #create-main-py }

Copy the example in a file `main.py`:

d.parent?a(this).parent():a(d.parent),e=c.find(".strength-meter"),f=a.formUtils.validators.validate_strength.calculatePasswordStrength(b),g={background:"pink",color:"#FF0000",fontWeight:"bold",border:"red solid 1px",borderWidth:"0px 0px 4px",display:"inline-block",fontSize:d.fontSize,padding:d.padding},h=d.bad;0===e.length&&(e=a("<span></span>"),e.addClass("strength-meter").appendTo(c)),b?e.show():e.hide(),1===f?h=d.weak:2===f?(g.background="lightyellow",g.borderColor="yellow",g.color="goldenrod",h=d.good)...
