# 9.2.0

ReleasedReleased on December 19, 2021

**Features:**

-   Cypress will throw an error when a user attempts to update a configuration value at run-time using either the Test Configuration or using `Cypress.config()` that is a [readonly option](/app/references/configuration#Test-Configuration). Addresses [#6407](https://github.com/cypress-io/cypress/issues/6407) and [#19001](https://github.com/cypress-io/cypress/issues/19001).
    
-   A `timeout` option has been added to the `cy.writeFile()` command, with a default value of `defaultCommandTimeout`. Addresses [#3350](https://github.com/cypress-io/cypress/issues/3350).
    
-   The default `maxHttpBufferSize` for the internal socket server has been increased to [Node's maximum Buffer size](https://nodejs.org/api/buffer.html#bufferconstantsmax_length) (size varies by OS) to allow large file writes with `cy.writeFile()`. Addresses [#19140](https://github.com/cypress-io/cypress/issues/19140).
    
-   Add `CYPRESS_VERIFY_TIMEOUT` environment variable to override the timeout duration of the `verify` command. Addresses [#18290](https://github.com/cypress-io/cypress/issues/18290).
    

**Bugfixes:**

-   Prevent unnecessary snapshotting when running default assertions that would unnecessarily increase CPU use in `cypress open` mode which lead to out of memory crashes on certain browsers. Fixes [#18549](https://github.com/cypress-io/cypress/issues/18549).
    
-   Removed automatic retries for failed HTTP requests through the proxy. This fixes an issue where failed requests could be re-sent too many times in some conditions. This change could increase the number of failed requests that your app sees. Fixes [#19043](https://github.com/cypress-io/cypress/issues/19043).
    
-   Reduced the occurrence of an issue where logs for `fetch` and `xhr` requests could be associated with the wrong request. Fixes [#19043](https://github.com/cypress-io/cypress/issues/19043).
    
-   Tests that are skipped within `then` blocks will no longer throw errors causing the test to fail. Tests that are skipped outside of `then` blocks will no longer trigger the fail event. This will prevent screenshots from happening from errors thrown by the fail event. Fixes [#14867](https://github.com/cypress-io/cypress/issues/14867) and [#17660](https://github.com/cypress-io/cypress/issues/17660).
    
-   Fixed a regression in [9.0.0](#9-0-0) where a fixture provided in a static response to `cy.intercept()` did not support passing `null` to encoding to read the fixture as a Buffer. This identified an undocumented [9.0.0](#9-0-0) Breaking Change where the default read behavior of a fixture changed from a Buffer to being read with `utf8` encoding. Fixes [#19344](https://github.com/cypress-io/cypress/issues/19344).
    
-   Fixed a regression in [9.0.0](#9-0-0) where `cy.contains()` attempted to ignore `<script>` and `<style>` elements found within `<body>`. by deleting them from the dom. This behavior was corrected to ignore the elements without deleting them. Fixes [#19377](https://github.com/cypress-io/cypress/issues/19377).
    
-   Cypress will no longer crash when proxying an ill formed request. For example, if the application under test has a resource of `"http: //localhost/asset.js"` (notice the extraneous space), Cypress will now log a debug message and the asset will fail to load. Fixes [#9220](https://github.com/cypress-io/cypress/issues/9220).
    
-   Correct `Cypress.Command.add()` and `Cypress.Command.override()` TypeScript types. Fixes [#18879](https://github.com/cypress-io/cypress/issues/18879), [#19095](https://github.com/cypress-io/cypress/issues/19095) and [#18940](https://github.com/cypress-io/cypress/issues/18940).
    
    -   Custom command implementations typings take into account `prevSubject` variants.
        
    -   Custom command implementations now allows to NOT return a value.
        
    -   Custom command overwrites typings take into account `originalFn` function.
        
-   Add types for `Cypress.session.clearAllSavedSessions()`. Fixes [#19363](https://github.com/cypress-io/cypress/issues/19363).
    

**Dependencies:**

-   Upgraded `ssri` from `6.0.1` to `6.0.2` to mitigate [ssri vulnerability](https://snyk.io/vuln/npm:ssri@6.0.1). Addressed in [#19351](https://github.com/cypress-io/cypress/issues/19351).
