Continuing from sbt 1.1.4, Ethan Atkins contributed fixes and improvements for triggered execution ~ watcher. sbt 1.1.5 should fix the latency between file modification events and the command execution.
We released a new sbt VS Code extension that starts sbt session in the embedded terminal window. This was contributed by Robert Walker (@WalkingOlof) in sbt#4130.
We added sbt by example to the sbt documentation. This is a single-page guide that takes you from zero to building an app on Docker, inspired by, and largely based on William Narmontas (@ScalaWilliam)’s Essential sbt.

One of the tricky things you come across while profiling is figuring out the process ID, while wanting to profile the beginning of the application.
For this purpose, we’ve added sbt.launcher.standby JVM flag. Starting sbt 1.1.4, you can run:
$ sbt -J-Dsbt.launcher.standby=20s exit
This will count down for 20s before doing anything else. launcher#51 by @eed3si9n
Using Flame graph (if you haven’t yet, check out Profiling JVM applications post), Jason Zaugg identified hashing code of the build file to be one of the hot paths during sbt startup. Flame graph supports Ctrl+F to filter on method names; and when I ran it, it showed 4.5% of the time was spent in Eval#evalCommon method.
Instead of creating an intermediate Array[Byte] and passing it to MessageDigest at the end, Jason suggested that we pass the arrays to MessageDigest#update in a more procedural style. After confirming that it worked, we’ve next identified file timestamp code to be the next bottle neck using Flame graph, so that was switched to using NIO. After both changes, Eval#evalCommon’s footprint reduced to 2.3%.
This means that your build loads slightly faster on sbt 1.1.4 (about 0.54s faster on akka/akka, for example). #4067 by @eed3si9n

^^. #3923 by @dwijnand
sbt 1.1.1 adds a new global Boolean setting called autoStartServer, which is set to true by default.
When set to true, sbt shell will automatically start sbt server. Otherwise, it will not start the server until startSever command is issued. This could be used to opt out of server for security reasons.

This adds unified slash syntax for both sbt shell and the build.sbt DSL.
Instead of the current <project-id>/config:intask::key, this adds
<project-id>/<config-ident>/intask/key where <config-ident> is the Scala identifier
notation for the configurations like Compile and Test. (The old shell syntax will continue to function)
These examples work both from the shell and in build.sbt.
Global / cancelable
ThisBuild / scalaVersion
Test / test
root / Compile / compile / scalacOptions
ProjectRef(uri("file:/xxx/helloworld/"),"root")/Compile/scalacOptions

sbt server feature was reworked to use Language Server Protocol 3.0 (LSP) as the wire protocol, a protocol created by Microsoft for Visual Studio Code.
To discover a running server, sbt 1.1.0 creates a port file at ./project/target/active.json relative to a build:
{"uri":"local:///Users/foo/.sbt/1.0/server/0845deda85cb41abcdef/sock"}
local: indicates a UNIX domain socket. Here’s how we can say hello to the server using nc. (^M can be sent Ctrl-V then Return):
$ nc -U /Users/foo/.sbt/1.0/server/0845deda85cb41abcdef/sock
Content-Length: 99^M
^M
{ "jsonrpc": "2.0", "id": 1, "method": "initialize", "params": { "initializationOptions": { } } }^M
sbt server adds network access to sbt’s shell command so, in addition to accepting input from the terminal, server also to accepts input from the network. Here’s how we can call compile:
Content-Length: 93^M
^M
{ "jsonrpc": "2.0", "id": 2, "method": "sbt/exec", "params": { "commandLine": "compile" } }^M
The running sbt session should now queue compile, and return back with compiler warnings and errors, if any:
Content-Length: 296
Content-Type: application/vscode-jsonrpc; charset=utf-8
{"jsonrpc":"2.0","method":"textDocument/publishDiagnostics","params":{"uri":"file:/Users/foo/work/hellotest/Hello.scala","diagnostics":[{"range":{"start":{"line":2,"character":26},"end":{"line":2,"character":27}},"severity":1,"source":"sbt","message":"object X is not a member of package foo"}]}}
The primary use case we have in mind for the sbt server is tooling integration such as editors and IDEs. As a proof of concept, we created a Visual Studio Code extension called Scala (sbt).
Currently this extension is able to:
compile at the root project when *.scala files are saved. #3524 by @eed3si9n
project/build.properties For all scripted tests in which project/build.properties exist, the value of the sbt.version property is read. If its binary version is different from sbtBinaryVersion in pluginCrossBuild the test will be skipped and a message indicating this will be logged.
This allows you to define scripted tests that track the minimum supported sbt versions, e.g. 0.13.9 and 1.0.0-RC2. #3564/#3566 by @jonas
