Changelog

← Back to Mister Plimsoll

1.1.6 (June 5, 2026)

• Per-volume alert cadence. Each volume in Settings > Volumes now has an ellipsis menu where you can set a different alert rhythm just for that drive — useful for backups or archival disks that don’t need the same frequency as your main one. Critical-override alerts still fire immediately at any cadence.
• Longer cadences, custom values. The check-interval picker now offers up to 24 hours, plus an Other… option that lets you enter any value in minutes or hours. Applies to both the global cadence and per-volume overrides.
• Fixed: three help links silently failed to open the browser. They open now.

1.1.5 (May 28, 2026)

• Fixed: the test-email feature under Notifications failed against Comcast and other SMTP servers that strictly validate the EHLO greeting. Mister Plimsoll now sends a fixed, syntactically safe EHLO greeting.

1.1.4 (May 28, 2026)

• Fixed: the test-email error report under Notifications was cropping the final character of every line returned by the mail server. SMTP responses now display in full.
• Added: a hint under the SMTP username field when the value lacks an “@”.

1.1.3 (May 26, 2026)

• First App Store release. Mister Plimsoll is now on the Mac App Store.
• Welcome screen. First-time users now see a brief welcome window on launch — a one-paragraph explanation that Mister Plimsoll is a menu-bar utility, plus a checkbox for whether to keep a Dock icon. You can revisit it any time from Settings > About > Show welcome screen.
• Dock icon by default for new installs. The Plimsoll mark now appears in the Dock alongside the menu bar by default on a fresh install; uncheck “Show Mister Plimsoll in Dock” on the welcome screen (or in Settings > Volumes) to go menu-bar-only. Existing installations keep whatever you had before.
• Fixed: a launch-time hang under the macOS App Sandbox. Mister Plimsoll spawns hdiutil and tmutil to detect mounted disk images and Time Machine destinations; that work now runs off the main thread, with a hard three-second timeout. Earlier builds could appear unresponsive on a fresh, cold-state launch if those helper processes stalled.

1.1.2 (May 24, 2026)

• Fixed: a small dark sliver could appear at the center of the screen while Mister Plimsoll was running. The on-screen alert window was being initialized at the wrong size on some Macs; restored an explicit baseline size so the window always renders at its proper dimensions.

1.1.1 (May 22, 2026)

• Fixed: the on-screen alert window now grows to fit long capacity readouts instead of truncating them mid-number.
• Fixed: the explanatory text under each section in Settings > Notifications now sits correctly within its section on every supported macOS version.
• Critical-threshold notifications. Notifications triggered by the critical-override threshold now carry a “Critical:” prefix in Notification Center, so an escalation stands out at a glance.

1.1.0 (May 16, 2026)

• macOS notifications. Alerts now arrive through standard macOS Notification Center too, alongside the existing floating banner. Default on; toggle in Settings > Notifications. Time Sensitive interruption level, so alerts punch through standard Focus modes.
• Webhook channel. A new Webhook section in Settings > Notifications POSTs alert JSON to any URL. Three formats: Generic JSON (Zapier, IFTTT, n8n, Home Assistant), Slack (drop in an Incoming Webhook URL), or Discord (drop in a channel webhook URL).
• Native SMTP. The email channel no longer shells out to curl; it talks SMTP directly via Foundation streams. Same provider support (STARTTLS on 587, implicit TLS on 465, AUTH LOGIN), nothing for users to reconfigure. Lays the groundwork for an upcoming Mac App Store edition where shelling out isn’t allowed.
• Fixed: Notification Center now shows the actual Plimsoll mark as the notification icon. Earlier builds shipped an incomplete AppIcon.icns with only 16/32/128/256 sizes; macOS fell back to a generic letter glyph at typical notification thumbnail sizes.

1.0.1 (May 11, 2026)

• Minor typographical fixes.

1.0 (May 10, 2026)

• Mister Plimsoll 1.0 is the first production release with no bugs reported and all intended features added.

0.7.0 (May 7, 2026)

• Treat purgeable space as free toggle in the Volumes tab. On by default (matching Apple’s “important usage” reading). Turn it off to count purgeable caches and snapshots as used; the percent climbs sooner and alerts fire earlier.
• Critical override threshold. A new checkbox in the Volumes tab; off by default. When you turn it on, set a percentage (default 95): any volume past that percentage will keep getting alerts even after its per-day cap is exhausted, with a 15-minute cooldown so you don’t get spammed.
• Email alert body now ends with a sentence explaining whether purgeable space is being treated as free or as used, so the recipient can read the percent in context.

0.6.15 (May 7, 2026)

• Pushover support. A new Pushover section in Settings > Notifications. Sign in to your Pushover account, paste your user key, pick a priority, and you’ll get push notifications on iPhone, iPad, Mac, or Android when a drive crosses your threshold. Includes a Send-test-push button. The user key lives in your Keychain.
• Fixed: clicking Settings… or Check for Updates… in the menu bar dropdown now closes the dropdown, as it should. Regression introduced when Settings became a regular Window scene in 0.6.11.

0.6.14 (May 6, 2026)

• Install DMG fixes: retina background bundled into the DMG so Finder uses the high-resolution version on hi-DPI displays, and the app/Applications icon positions adjusted to align with the arrow on the background.

0.6.13 (May 6, 2026)

• Purgeable space explainer. A short note at the bottom of the Volumes tab spells out what the “purgeable” column means: cached data, local copies of iCloud files, and old snapshots that macOS will automatically reclaim when you need the room.
• Fixed: the Refresh button no longer shifts position as you change the check interval. The label now reserves space for the widest value so the controls stay put.

0.6.12 (May 4, 2026)

• Discrete check-interval steps. The Check every N minutes stepper now snaps between sensible values: 1, 5, 10, 15, 30, 45, 60.

0.6.11 (May 2026)

• Resizable Settings window. You can now drag the bottom edge to make the Settings window taller (e.g. when you have a lot of monitored volumes). Width stays fixed.

0.6.10 (May 2026)

• Check for Updates in the About panel. Settings > About now has a direct link next to the version, in addition to the menu bar item.
• Volumes tab. Refresh moved next to the check-interval stepper, and the gap above the volumes list tightened.
• Apple Account. “Apple ID” updated to “Apple Account” throughout, matching Apple’s current naming.

0.6.9 (May 2026)

• Fix for Messages permission. Every release from 0.6.0 onward shipped without the com.apple.security.automation.apple-events entitlement — the release script’s re-sign step was silently stripping it. macOS’s hardened runtime then blocked AppleEvents before TCC could prompt, so users got “permission needed” with no system dialog ever appearing, and Reset and try again couldn’t fix it. 0.6.9 preserves entitlements through re-sign and verifies the result before notarization.

0.6.8 (May 2026)

• Test-send error messages now wrap fully and stay readable instead of getting truncated mid-sentence.
• When Messages.app permission is missing or stuck, the Settings panel shows an inline Reset and try again button that clears macOS’s permission record and immediately re-tries the send. No more typing tccutil commands in Terminal.

0.6.7 (April 2026)

• Universal binary. Mister Plimsoll now ships as a true universal app (arm64 + x86_64). 0.5.0 through 0.6.6 were unintentionally Apple-Silicon-only and refused to launch on Intel Macs with a “not supported on this Mac” error. Intel Mac owners can now install and run the app.

0.6.6 (April 2026)

• Polished install DMG: drag-to-Applications layout with a sky-blue background, large icons, and a labeled arrow so first-time users know exactly what to do.

0.6.5 (April 2026)

• In-app updates via Sparkle. Mister Plimsoll now checks for updates automatically and offers to install them in place. There’s also a Check for Updates… item in the menu bar dropdown for manual checks. Future versions will arrive without you having to download the DMG by hand.
• Email alerts redesigned: rich HTML with site typography (using Merriweather Sans), a single-row table with column headers, and a plain-text version for clients that prefer it. Free amount highlighted in red.
• Purgeable space (APFS caches and snapshots) shown as a separate column in the email so you can tell what’s truly free vs. reclaimable.
• Email footer explains how the recipient was opted in and how to disable alerts, with an inline Plimsoll-mark glyph to help locate the menu bar icon.
• Contact address — misterp@misterplimsoll.app — in the About panel and footer.

0.6.0 (April 2026)

• Fix: Messages.app integration. Hardened-runtime entitlement was missing, which silently blocked AppleEvents to Messages and prevented macOS from prompting for Automation access. Users on 0.5.0 saw an empty Privacy & Security > Automation list and had no way to enable iMessage alerts. 0.6.0 ships the entitlement so the prompt actually appears.
• Purgeable vs. truly free space. The Volume model and every display now distinguishes raw free bytes from APFS purgeable storage. You see both numbers wherever capacity appears, and totals reconcile.
• Live drive list in the menu bar dropdown. Each monitored volume gets a row showing icon, percent used, mini progress bar, and the free / purgeable breakdown.
• Show in Dock toggle. Optional Dock-icon presence; default off (menu bar only).
• First-launch: Settings opens automatically on first run so you can pick volumes and set thresholds without hunting for the menu bar.
• Cleaner alert window. Compact one-line capacity readout with the free amount in red.
• Single-line schedule row in Settings, with Launch-at-login and Show-in-Dock toggles on the right.
• Editable thresholds. The per-volume Alert and Max-per-day fields accept typed values as well as stepper clicks.
• Animated Check Now in the menu bar: spin while checking, then a green checkmark for two seconds.
• Mounted disk images (.dmg installers, sparsebundles) excluded from the monitored list so they don’t clutter Settings.

0.5.0 (April 2026)

• First public beta. Menu-bar utility that polls mounted volumes on a configurable interval and warns when any of them crosses a per-volume threshold.
• Alert channels: on-screen banner window, email via SMTP (with credentials in macOS Keychain), and Messages.app (iMessage).
• Per-volume settings: monitor toggle, threshold percentage, daily alert cap.
• Time Machine destinations detected and labelled.
• Launch at login (via SMAppService).
• Signed with a Developer ID Application certificate and notarized by Apple.
