This week I focused on improving cosmic-lib SEP-0007 support.
SEP-0007 is the SDF answer to CosmicLink, and while it is not as polyvalent and
secure, it is worth supporting to not let anybody left out. The role of
Cosmic.plus is to unite, not to divide.
You can play with the last iteration of the library
[here](https://cosmic.plus/js-cosmic-lib/web/demo). The last step toward full
compatibility is signature verification.
I published the web bundle for `@cosmic-plus/loopcall`. You'll find details in
I also released `@cosmic-plus/ledger-wallet`, Stellar Authenticator and Cosmic.link as 1.0.0. No big change here, but
this is stable so it was about time to make it official.
Finally, I continued my work on improving Cosmic.plus documentation framework,
release automation, and naturally, I wrote the Pen of the Week.
The priorities for next week are:
1. cosmic-lib: Implement SEP-0007 signature verification.
2. cosmic-lib: Port Equilibre.io's side-frame.
3. cosmic-lib: Support requests from HTML forms.
## Pen of the Week: ledger-wallet, Sign transaction
This pen makes use of `@cosmic-plus/ledger-wallet` and `stellar-sdk` to sign an XDR-encoded Stellar transaction with a Ledger Wallet.

## Update application: Equilibre.io 1.0.5
- Fix spread percentage definition: `100*(bestAsk-bestBid)/midpoint`.
## Update application: Cosmic.link 1.0.0
**Note:** This major release doesn't contain any breaking change. The version
bump only means that this software is public and stable.
- Add SEP-0007 `pay` support.
- Fix Ledger Wallet support for older browsers.
## Update application: Stellar Authenticator 1.0.0
