SAMPLES & IGSN • IGSNs from strabospot.org: IGSNs now come from your strabospot.org account, so the app no longer signs in to or registers with SESAR • IGSNs on strabospot.org: View IGSN and Get IGSN open the sample's own page on strabospot.org • Upload first: a sample not yet on your account offers to upload the project, then opens its page when the upload is done • IGSN edits reminder: editing a sample that has an IGSN reminds you to upload so strabospot.org can update it • Correct sample location: a sample from an image-basemap Spot gets a real-world location FORMS & VALIDATION • Live form validation: errors show as you type and Save stays disabled until they're fixed • Find the problem field: the tab holding an unanswered field is marked so you know where to look • Auto dip direction: entering a strike fills in the matching dip direction wherever you type one • Negative numbers on iOS: type negative values, with a keyboard matched to the field • Sensible limits: number fields reject impossible values, like negative thicknesses, percentages over 100, or azimuths past 360 • Number pad on iOS: fields that can't be negative open the number pad instead of the full keyboard COMPASS • Automatic declination: magnetic declination is recorded and kept up to date in your project data • Declination without GPS: falls back through your project location and nearby Spots to stay corrected, with clearer warnings when it can't • Lineation hint: "Align long side with lineation" shows for linear measurements LOCATION • Location button spinner: the Geography location button shows a spinner while it waits for a fix • Location checked first: shortcuts and geolocate check that location is on and allowed before they start, and tell you if it isn't • Clear location errors: a failed location lookup says why, and shortcuts no longer leave the spinner running • Location Services off: a separate message tells you to turn Location Services back on in Settings • Coordinate checks: Geography coordinates must be numbers, so a typo can no longer leave a Spot without a location MEASUREMENTS • Bulk strike/dip: calculate missing strikes and dip directions for every record that holds a plane • Steadier validation: planar+linear and 3D-structure measurements are checked and hinted more reliably TAGS • Memos on tags: add, remove, count, and list a tag's memos from its detail page • Cleaner tag counts: a tag's counts show as icon chips instead of a legend • Sample tagging: only samples that have their own Spot can be tagged • Synced tags stay current: saving a tag after an auto-sync no longer overwrites edits made on another device MEMOS • Memo authorship: memos record who wrote them and when • Associated samples: link samples to a memo, including legacy samples, from the Memo modal • Memos in Overview: a Spot's memos now show in its notebook Overview NOTEBOOK & PAGES • Feature labels: every feature list shows a label, filled in on save • Full Spots list: see the full Spots list when no Spot is selected • Collapsible More Pages: the More Pages sections collapse like the main menu's • Tidier Overview: Sedimentary Rocks is hidden from the Overview when no lithology has rock data LISTS & DATASETS • Remembered sort: each list keeps its sort order and reverse sort, applied before the first paint • Active dataset names: lists name the active datasets at the top, with a shortcut to open Datasets • Map filter for Spots: filter Spots by whether they're on the geographic map or not mapped • Edited Spots stay put: editing a Spot on the map no longer also adds it to the target dataset, so it can't vanish from its own dataset after an upload • Fix Spots in two datasets: on the Metadata page, tap a dataset to move a Spot listed in several datasets into just that one Full notes: https://github.com/StraboSpot/StraboField/releases/tag/v2.32.0 Thanks for using StraboSpot!

PHOTOS • Taking photos on iPad: taking photos, especially several in a row, no longer crashes the app MEASUREMENTS • Steady compass for lineations: trend and plunge are always taken along the top of the screen, which now stays in portrait while the compass is open, instead of sometimes reading 90° or 180° off depending on how the device was held. The live strike/dip and trend/plunge are shown under the compass NOTEBOOK & NAVIGATION • Zoom to Spot: zooming to a Spot opened from the Spot Navigator no longer crashes or reopens the navigator • Notebook tab on phones: the Notebook tab no longer goes blank after opening a project • Notebook from the image viewer: the Notebook button opens the Notebook instead of a second map PHOTOS & BACKUPS • Photo resize errors: a photo that fails to resize shows an error instead of closing the app • Re-importing backups: images already on the device are copied correctly when a backup is imported again MAPS & SIGN-IN • Downloaded custom maps: a custom map without an id no longer stops a downloaded project's custom maps from loading • Forgot password: when the reset link can't be opened, the sign-in screen tells you where to reset it Thanks for using StraboSpot!

MEASUREMENTS • Compass over template: a fresh compass reading now takes priority over an active template • Strike from dip direction: entering a dip direction fills in the strike instead of writing NaN PHOTOS • Photos picked together: several photos saved at once no longer collide and overwrite each other READ-ONLY DATASETS • Spots stay out of read-only datasets: Spots can no longer be moved, copied, or created into a read-only dataset • Locked samples and features: Add Data to Sample, Get IGSN, and Other Feature fields are disabled on read-only Spots SAMPLES & IGSN • SESAR sign-in when saving: saving a sample with an IGSN prompts you to sign in to SESAR when needed • Works with SESAR's new system: signing in, registering, and updating IGSNs now use SESAR's latest API FORMS & DATA • Same-day date ranges: an equal start and end date no longer fails validation • Correct sed choices: "masses" (diagenesis) and "Supratidal" (environment) now save as their own values • Mineral lookup: looking up a mineral keeps the data already entered, and a mineral with no name shows Unknown • Template deletions sync: deleting a template marks the project as changed SMALL TOUCHES • Map editing: Edit goes straight to the selected Spot when it is on the current map • Halted collaborations: an owner's project shows in the server list again once its collaboration is halted • Project screen on tablets: shows as a centered box instead of fullscreen • Profile photo: a camera or gallery error no longer breaks setting a profile photo • StraboField naming: permission prompts and support email now say StraboField Thanks for using StraboSpot!

STABILITY • Fewer crashes: fixed iOS crashes that could occur when switching between modal screens Thanks for using StraboSpot!

Bug fixes for image deletion and sketch

• QAQC: Run QAQC button is now hidden for read-only projects and datasets, preventing accidental edits (testing only) • Modals now consistently show a close button whenever a cancel button is visible • Fixed a bug where a missing server image could cause a crash • Updated QAQC icons for a cleaner look (testing only) • Bug fixes and stability improvements

New Features Photo Compass Data - Photos now capture view azimuth and plunge angle at the moment they are taken, giving your images richer spatial context tied to your field measurements. Scale Bar Unit Toggle - Switch the map scale bar between metric and imperial units directly from the map actions modal. Selective Backup - Choose exactly what to include when backing up a project: images, offline tile caches, and custom maps can now be backed up or excluded individually. Tags and Geologic Units - Searching, sorting, an filtering are added (including Temporal sort for Geologic Units). Temporal Sort for Geologic Units - Geologic Units pages now sort by geologic age, with support for age modifier fields. Dike as a Planar Orientation Type - "Dike" is now available as an option in planar orientation forms. Tappable Empty State Text - Empty list placeholders in the Notebook (e.g., "No Measurements") are now tappable and navigate directly to where you can add data. Bug Fixes Fixed a long-standing issue where photos taken in portrait orientation on iOS were saved rotated 90°. Increased the network timeout from 60 seconds to 5 minutes to prevent false timeout errors when uploading large projects.
