🚀 Browser4 v4.14.1 Release Notes

Release Date: 2026-10-17 05:40:34 UTC
Java Version: 25+
Built by: @galaxyeye

Browser4 4.14.1 is the first maintenance release of the 4.14 line: two large issue batches from the scenario evaluations land as fixes, and two defects that broke everyday CLI commands are gone.

  • Every command with a positional argument works again. The option validation added with the 20261013 batch treated the dispatcher's positional slot as a misspelled flag, so open <url> failed with "unknown option --url" - together with goto, new-tab, crawl, console, scrollintoview, highlight, snapshot grep, webminer install, code replace and mousemove.
  • --json prints exactly one document. network requests --json emitted the raw buffer plus the envelope (which jq rejects), and network routes claimed e2e coverage it never had; both now record native JSON inside the envelope, and the routes command is asserted end to end.
  • Two issue batches closed. 139 issues from the 20261013 evaluations and 132 from the 20261015 ones are fixed and verified across agent lifecycle, the five plugin modules, snapshot/htmlsnapshot/inspect, crawl/loop and attach/session/tabs/window - counts, envelopes, selector quoting and liveness reasons were the recurring themes. The 20261016 batch (19 issues) is filed for triage.
  • Agent retries stop swallowing cancellation. run() rethrows CancellationException instead of retrying past it, gates retries on RetryStrategy.shouldRetry, applies the backoff its timeout budget already accounted for, and reports an inference timeout as a timeout instead of a user cancellation.
  • New launch switch. browser.extensions.inherit=false adds --disable-extensions at the single launch funnel, so a profile's live extensions can no longer inject their content script into a session that must stay pure (the default stays true). The base library moves to the released 4.11.25.
