# EPF Dev Update #12 This update contains my work done on weeks 15 and 16 of the EPF (2023-10-23 to 2023-11-05). **tl;dr:** - Iterated my Engine API article. - Started preparing my devconnect talks. ## Finalized engine API guide. [Mikhail Kalinin gave me feedback on my engine API article.](https://discordapp.com/channels/595666850260713488/1164771164237864970) I solved the issues he raised, and now the article is ready! [He opneded a pull request](https://github.com/ethereum/execution-apis/pull/483) to have the article included in the API spec. After the PR is merged, it will be found on the [readme](https://github.com/ethereum/execution-apis/tree/main/src/engine). ## Preparing my devconnect talks. I will be giving two talks at devconnect. One will be with Jason Carver on the Ethstaker Staking Gathering; the other will be my final presentation on the EPF day. I decided to start with the one for the EPF day. I have the slides almost ready, but I will probably make some changes in the coming week while I write my final dev update.
