Cypress v3.3.2. Source highlight: *Released 6/27/2019*

## New Features
- Added a section on how to opt out of sending exception data to Cypress in the Installing Cypress doc.

## Bug Fixes
- We fixed a regression introduced in 3.3.0 that was causing the Test Runner to do extremely unnecessary re-renders of the Command Log on any command change - leading to exponential performance degradation on any run. This was the root cause behind many users experiencing a reduction in performance when upgrading to `3.3.0` or above. Fixes #4411 and #4313.
- We reduced memory consumption and improved the performance of running tests anytime you're inside of `cypress open`. Fixes #2366. Thanks @"CoryDanielson"!
- We no longer delay proxied responses with no body with status codes 1xx, 204, 304. This fixes a regression introduced in 3.2.0 where responses with these status codes were delayed when using a proxy. Fixes #4298.
- Snapshots were previously being mistakenly stored then instantly deleted when `numTestsKeptInMemory` was set to 0. We now no longer record the snapshots at all when `numTestsKeptInMemory` is set to 0. This should slightly improve the performance of running tests with this setting. Fixes #4104 and #4164.
- Cypress no longer watches files when run using `cypress run`. This will fix some runs that were crashing with an `ENOSPC` error. Fixes #4283.
- Cypress now correctly handles `blur` and `focus` events in situations where the browser has lost focus. Fixes #4039, #1176, and #1486.
