v. 2.2.0 -- 13 November 2019 This new version brings enhanced iOS 13 compatibility as well as a few important bug fixes. The iOS 13 sharing panel will no longer freeze the app, maps have been improved, and a bug in the GPS thickness calculation routine that would trigger under certain conditions has been fixed. Also, this version can now import Strat Desktop data on the clipboard, which was broken in recent versions, and you can now add formation names to your data. Though there is no significant new functionality in this version, you should definitely update if you are using recent versions of iOS on your device.

v. 2.0.1 — 2018.04.29 • Bug fix for case of incorrectly formatted clipboard text when importing lithology types. v. 2.0.0 — 2018.04.16 • A new view allows you to enter the grain size at the base and top of a unit and select a description of the basal contact (e.g., erosional, gradational, etc.). Specifying a different top and base grain size will cause the right hand boundary of the unit in the column to be drawn on a diagonal to reflect fining or coarsening upwards. Clastics use a different classification than carbonates. You access this view from the "More" button in the upper right corner of the Interval Details screen. • Use a two fingered pinch gesture to shrink or expand the scale of the column shown on the section page. Once shrunk or expanded, you can use a one fingered drag in the column to scroll to the part that you want to see. Double tapping a unit will still take you to the interval details view. To return to the default view with the entire column on the screen, simply go to any other view and then return to the section view. • Incorporation of macrostrat.org lithology types, groups and names as well as official colors. To access these terms, tap the strat column icon on the bottom of the section view and then tap the new button to bring up the lithology definition screen. You will see three spinner controls. In the top two side by side controls, you can select the macrostrat type and group designations and in the bottom one select the lithology name. Alternatively, you can just start typing the lithology name and Strat Mobile will select any matching entries in the macrostrat listing. The color bar sliders are selected automatically to yield the color for the lithology type defined in the macrostrat database, although you can override those after setting the lithology. Any existing lithologies that you have defined will be searched for to see if they match the macrostrat sedimentary rock type listing and will assign the type and group characteristics, but will not override your color selection. Note that you can define the lithologies that you want and save them as default lithologies for a new section. You may also want to define a lithology type called "gap" or some such thing and assigned a white color for covered intervals. • You can now use the system clipboard to import lithology definitions to suit your project or desktop software by clicking the the Import Clipboard button in the lithology type view (reached by tapping the column icon on the Section view). Thus you can store different sets of lithology definitions for different projects or classes in, say, Notepad and then copy and paste them into Strat Mobile as needed. Pasting new lithologies in does not replace any lithologies that already have intervals assigned to them, nor will it duplicate any existing lithology types, but it will erase any unused lithology types. Lithology definitions may be exported from the same view using the new "Share" button at the bottom of the screen. • This version of Strat Mobile has a new output file format to accommodate the new data functionality. It will read your old data files but any file saved with this version will not be readable by older versions of the program. The name of the section is now included in the first line of the data file and is automatically displayed when restored from the RecoveryFile. Strat Desktop, available at http://www.geo.cornell.edu/geology/faculty/RWA/programs/strat-desktop.html has been updated for compatibility. • New organization, much faster operation, and more stable, less memory intensive design of the Data List View, espcially with there are a large number of intervals/samples. • Moved the Section Name text field to the top of the screen so it will not be covered by the keyboard. • The GPS is off reminder message in the Section.Jacob staff view can be dismissed permanently for the session by tapping the "Stop Prompting Me" button the first time it appears.

v. 1.0.1/1.0.2 - 21 March 2018 • (v. 1.0.2 fixes a crashing bug entering samples while making a tape measurement that was introduced in v. 1.0.1) • Shares the same file format with the new desktop companion app at http://www.geo.cornell.edu/geology/faculty/RWA/programs/strat-desktop.html • The trash can icon on the Data List view is now called "New" because you typically use this button to clear the app of old measurements so you can enter a new section. • Minor change to the data file format to work around an issue when mailing data whereby the mail program would strip out consecutive tab characters. Blank columns are now indicated by an underscore character. Old data files should continue to work just fine. • Fixed a bug where changing units would not change the units on the samples. This should now work just fine.
