    @mstepien Hi, Magda. Do you have more details about the update? I am in the half way lerning the course. Currently I am learning the chapter 6. Do I have to go over the first 5 chapters? Thank you!

    Hey @krave - no you shouldn't need to redo 1-5. Most of the updates in LFW212 revolve around node core, tooling, framework and library updates but if you managed to understand and complete 1-5 recently then you're good.

    You will want to switch from Node 12/npm 6 to Node 16/npm 8 while using the material however. See chapter 1 of the updated content to install the latest targetted Node version for the certification.

    Hi Magda (@mstepien),

    Sorry to hijack this thread, but I just noticed the links to Fastify docs are broken. Not sure when this happened, but the docs have an additional path parameter: /Reference, so the ones from the course result in a 404.

    This is where I noticed:
    Chapter 09 - Web Security: Handling user input, on the page: Route Validation with Fastify (2). In the course, we have the links:
    https://www.fastify.io/docs/latest/Routes/#options and https://www.fastify.io/docs/latest/Validation-and-Serialization/#validator-compiler when they actually have to be https://www.fastify.io/docs/latest/Reference/Routes/#options and https://www.fastify.io/docs/latest/Reference/Validation-and-Serialization/#validator-compiler, respectively.

    I haven't checked other pages yet, but I have a feeling this case will be throughout the course.

    Thanks,
    Alex
