Since I missed last week’s dev update, this week will overview work from previous 2 weeks.

**1.0.11 Release**  
Various issues for the upcoming [1.0.11 release](https://github.com/zcash/zcash/projects/16) have progressed including adding a field to `listunspent` output to show whether the UTXO is a coinbase transaction ([#2446](https://github.com/zcash/zcash/issues/2446)), a restriction to spending from shielded addresses when `minconf=0` ([#2519](https://github.com/zcash/zcash/issues/2519)), removing UPnP support ([#2500](https://github.com/zcash/zcash/issues/2500)), etc.

We also sent out an alert to remaining 1.0.10 nodes enabling safe mode as part of this milestone.

We have an updated release process we’re trying which involves deploying and testing a release candidate 1 week prior to main release. Next week should see the RC for 1.0.11 and testing with the following week deploying the regular 1.0.11 release. This updated process comes as a result of our mistake in the 1.0.10 release which required a 1.0.10-1 hotfix (the current version). The goal is to drastically reduce any need for hotfix releases in the future by catching issues in the RC.

**Beswick**  
Progress was made on design for a new RPC `z_shieldcoinbase` for shielding all coinbase UTXOs in wallet ([#2448](https://github.com/zcash/zcash/issues/2448)).

Other tickets in the Beswick project can be tracked [here](https://github.com/zcash/zcash/projects/15).

**Sapling**  
We’ve been researching and working on the BLS12-381 elliptic curve upgrade which can be tracked in the following tickets: [#2502](https://github.com/zcash/zcash/issues/2502) & [#2517](https://github.com/zcash/zcash/issues/2517).

Sapling working group meetings continue to run regularly and overall we are making good progress.

Other tickets in the Sapling project can be tracked [here](https://github.com/zcash/zcash/projects/7).

**Dev outreach**  
Our team has been doing a lot of outreach the past two weeks as well: Zooko and Paige were in China meeting businesses and developers; Str4d and Sean attended [PETS](https://petsymposium.org/2017/) (which ZcashCo was a sponsor for) & Ariel and Jay participated in the [IC3 Ethereum bootcamp](http://www.initc3.org/events/2017-07-13-IC3-Ethereum-Crypto-Boot-Camp-at-Cornell-University.html) and as a result made a lot of great progress on the implementation of ZEXCAT (Zcash-Ethereum).
