NIP-44 v3 adoption is going really well. Here's some updates:
First, Amber supports NIP-44 v3 now 🎉 Thanks @greenart7c3!
For Go users, there is now v0.1.0 of ncrypt-go. This is a minimal library for Nostr encryption with support for NIP-44 v3, v2 and NIP-04:
An extension to NIP-17 private messages that allows backwards compatible upgrades to NIP-44 v3 is also available now:
NIP-44 v3 support in Nostr Build Shack is planned, but it's going to take a bit. @The Fishcake (nostr.build) is very busy upgrading @nostr.build, and it requires some major changes to the extension core 🫡
Support is also coming to @Clave by @⚡️ᗪㄖ匚⚡️, very soon.

## Amber 6.2.0
- Add NIP-44 v3 encryption support, including a dedicated approval screen, intent preview, bunker preview, history logging and auto-reject for invalid requests
- Register NIP-44 v3 ContentProvider authorities
- Auto-accept NIP-46 ping requests on connect
- Ignore empty `` intents so the app can be opened directly
- Simplify the invalid intent screen to only close the app
- Use a segmented toggle for option pickers, with a scrollbar and shrinking segments when they get too narrow to fit the screen
- Remove the `sign_message` signer method
- Remove the 1 minute option from the sign-automatically pickers
- Disable resource shrinking in release builds
- New Crowdin translations

## Verifying the release
In order to verify the release, you'll need to have `gpg` or `gpg2` installed on your system. Once you've obtained a copy (and hopefully verified that as well), you'll first need to import the keys that have signed this release if you haven't done so already:
``` bash
gpg --keyserver hkps://keys.openpgp.org --recv-keys 44F0AAEB77F373747E3D5444885822EED3A26A6D
```
Once you have his PGP key you can verify the release (assuming `manifest-v6.2.0.txt` and `manifest-v6.2.0.txt.sig` are in the current directory) with:
``` bash
gpg --verify manifest-v6.2.0.txt.sig manifest-v6.2.0.txt
```
You should see the following if the verification was successful:
``` bash
gpg: Signature made Fri 13 Sep 2024 08:06:52 AM -03
gpg: using RSA key 44F0AAEB77F373747E3D5444885822EED3A26A6D
gpg: Good signature from "greenart7c3 <greenart7c3@proton.me>"
```
That will verify the signature on the main manifest page which ensures integrity and authenticity of the binaries you've downloaded locally. Next, depending on your operating system you should then re-calculate the sha256 sum of the binary, and compare that with the following hashes:
``` bash
cat manifest-v6.2.0.txt
```
One can use the `shasum -a 256 <file name here>` tool in order to re-compute the `sha256` hash of the target binary for your operating system. The produced hash should be compared with the hashes listed above and they should match exactly.
