☕ Java requirement — depends on how you install

Install mode	Java needed?
Self-contained bundle — browser4-cli install	None — the bundle ships its own jlink-built JRE
browser4-cli binaries / npm install -g browser4-cli	None — native binary
Standalone Browser4.jar (java -jar)	Java 25+
WebMiner (browser4-cli webminer)	JDK 17+ — auto-detected (the bundle's JRE also satisfies it)
Build from source	JDK 25+ to compile; JDK 25 enables the JVM AOT cache (JEP 483/515)

Browser4 v4.16.5

Base library upgraded to browser4-base 4.11.31 (published 2026-11-11): vi boxes are
document-absolute, compute() no longer scrolls the page, and the mouse/pointer fixes are
consumed from Maven Central instead of a local 4.11.31-SNAPSHOT install.

• make agent run output readable

• let a task read Browser4's data, temp and code roots

• forward coordinate options and convert boxes horizontally

• make pointer and box coordinates unambiguous end to end

• accept -o as the short form of htmlsnapshot query --output-file

• recognize task inputs glued to CJK punctuation and quoted paths

• bound auto-update retries and dedupe concurrent prefetches

• record the live option checks (space/steps/allow-outside/viewport-boxes)

• record commit hashes and the final CLI test count

• trim attach.md and browser-modes.md under the M6 500-line cap
