Community Update - September 2020
As mentioned last month we're turning our former announcement post into a community update. Below you'll find everything our community has been up to over the past month.
Update: 1.5.0 has been released and you can read the full release notes here.
What's New in the Ecosystem
Firstly we will be holding two community open door sessions for the 1.5.0 RC, one for US-based timezones and one for APAC.
We might be a lot about Daml but we're not *just* about Daml. Our biggest piece of news this month is that @cocreature just handed over maintenance of ghcide to the Haskell community, and they’re super-excited. This has major benefits for both Haskell and Daml as more maintainers will lead to more useful features in Haskell and Daml IDEs. Check out the rest of the details here. ♀️♂️
Our second Community Recognition Ceremony has kicked off. We do these quarterly to make sure our community members get the recognition they deserve for all of their wonderful contributions. Nominate who you think deserves to win here!
Block8 just started a 4 part series comparing the upsides and downsides of Daml vs. Java on Corda. It’s a seriously explosive review covering state, transactions, ease of development, testing, and functionality.
@gyorgybalazsi took a deep dive into the Daml Finance library in the second post of his Daml master class. Covering big ideas like semantically rich identifiers, modularity, and multistep settlement chains. Few have explored the depths of the finance library like György has. György also found a bug where Ordering didn't have a Show instance, so now it does. Thanks!
@Amy_Ahmed , @andreolf, @talia.klein, @Felix_Kam, @ManishGrover, and myself (@anthony) spent the last month mentoring students and participating at the hackbfs.com ideation-a-thon. It’s been a great experience being able to share our knowledge with the next generation of builders.
Release Candidate for Daml SDK 1.5.0
1.5.0 RC Highlights
- Daml Script is now fully integrated into the IDE and will supersede Scenarios.
- Turn Daml expressions into JSON using the REPL (ex.
:json [1, 2, 3]) which is useful for talking to the JSON API.
- Daml on SQL now has much richer logging which means error messages will be a lot more transparent, allowing you to see exactly what call data caused an error. We’re also adding support for structured logs via Logstash Logback Encoder.
foldrperformance has improved by 4x! 4x faster folds IN. ANY. DIRECTION. YOU. WANT.
- Application IDs now work in Daml Script, Triggers, and REPL. Useful if you’re working with ledgers with authentication.
- The Trigger Service can now bind to addresses other than localhost.
We are continuing to work on performance of the Daml integration components and improving production readiness of Daml Ledgers, but there are exciting features and improvements in the pipeline for the next few releases as well.
- The Trigger Service will reach feature completion and move into Beta
- The authentication framework for Daml client applications (like the Trigger Service) is being revisited to make it more flexible (and secure!)
- Daml's error and execution semantics are being tidied up with a view towards improving exception handling in Daml
- Daml will get a generic Map type as part of Daml-LF 1.9
