Good afternoon developers and welcome to this week's edition of developer weekly! In this week's issue, we're excited to talk about episode 3 of the ICP Developer Journey video series, the recent 'Let's Talk ICP-ETH integration' talk, and the latest Motoko release, v0.10.2. Let's get started!
Episode 3 of the Developer Journey video series
Episode 3 of the video series corresponding to the developer journey tutorial series is now live on the DFINITY YouTube channel! In this episode, we walk through how to set up your developer environment by installing IC SDK, Node.js, and getting familiar using a command line interface through gaining a basic introduction to using CLI commands.
New episodes of the developer journey are released every week, and will correspond to each tutorial included in the developer journey series on the developer documentation.
You can find the video tutorial on YouTube here.

This week, Motoko version 0.10.2 was released! Some important takeaways from the release notes include:
A breaking change where values of type
Principalare now constrained to contain at most 29 bytes. This matches ICP's notion of a principal. In this change specifically:
An actor import will be rejected if the binary representation of the aliased textually encoded principal contains more than 29 bytes.
Principal.fromBlob(b)will trap if
bcontains more than 29 bytes.
The actor literal (actor
<exp>) will trap if the binary representation of the textually encoded principal
<exp>contains more than 29 bytes.
A bug fix to separate
underscorein coverage warnings.
Code compiled for targets WASI (-wasi-system-api) and pure Wasm (-no-system-api) can now use up to 4GB of stable memory.
A bug fix to fully implement Region.loadXXX/storeXXX for
A bug fix in
Array.tabulateVarto avoid repeated side effects.
