• Recordings now warn you when your Mac is busy or locked. • A recording now stops and is analyzed shortly before the five-minute limit instead of being lost. • The command line can record the newest matching build, so a rebuild no longer invalidates it. • A single hang is now one finding, with its blocked segments shown as supporting evidence. • CPU hotspot titles now name the dominant app symbol. • A full disk is now reported clearly instead of as a generic failure.

• Saving a recording no longer looks stuck: the progress bar keeps moving, shows how long the save has taken and the trace size (with an up-to-date Recorder Companion), and Cancel stops the save instead of waiting for it. • Analysis starts sooner after a recording, saving roughly 15–20 seconds on large traces. • The agent CLI never hangs when RocketTrace is paused or starting, can reset a stuck recording, record on a chosen Simulator, and compare the newest results of two labels. • Simulator recordings recover app symbols more often, and Simulator builds no longer pick a connected iPhone as the destination. • Recording is more resilient: transient start failures are retried automatically, and failures explain what to try next, including a Repair option when the Recorder Companion does not respond.

• Finds more kinds of performance problems: long hangs are split into busy and blocked time, with new findings for worker threads serializing on one lock, main-actor tasks waiting on a task group, repeated DateFormatter or NSRegularExpression construction, and SwiftUI views updating on a steady cadence. • Adds thermal state, priority inversion, filesystem, Core Animation phase, and library-load evidence to results when the matching Instruments tables were recorded. • New recordings capture more instruments (requires an up-to-date Recorder Companion). • Agent CLI: query several symbols at once, rank SwiftUI view cost for any window, and list recorded signposts. • Recording is more reliable: automatic retry after a failed start, clearer messages when the app exits before attach, and no more hangs when canceling. • Large traces use much less memory, and RocketTrace checks free disk space before recording and analyzing. Existing results show that a newer analysis is available.

More accurate CPU findings: idle waits no longer look like busy cores. Recordings catch missing symbols up front, and stuck sessions recover without restarting Companion. New: - Pass launch arguments and environment into a fresh recording from the CLI and Agent - Mark, cancel, and window a recording; compare scenario runs and attach your own metrics - Sample Simulator processes and top host activity while you record - Reanalyze an outdated result from its retained Instruments trace Improved: - Hang attribution skips run-loop scaffolding that isn’t the real cause - Companion update unlocks launch conditions and process sampling when a recording needs them Fixed: - Technical Details no longer crashes in a minimum-size results window - Incomplete imports and unfinished Instruments saves explain what to do next - Stuck recordings stop endless retries and tell you how to recover
