IMPORTANT: This is a major release. If you have critical databases, you MUST back them up before updating this app. To back them up, share them with your computer or iCloud, or upload to Dropbox.

- More documentation for SQL functions
- New search bar for SQL functions
- SQLite 3.32.3
- Bug fixes

Although this is a minor release, it is good practice to back up any critical databases you have before updating the software.

Hide tables and views in the List of Tables. This helps when working with databases that have a lot of tables and views, some of which you rarely use. It can also be useful if you are distributing your databases to others, who do not need to see all the tables. To hide a table or view, go to the List of Files, tap your database file, then tap the table or view you wish to hide and tap the "Hide" button. To un-hide it, do the same thing but tap the "Show" button. To temporarily display the hidden tables and views in the List of Tables, long-press the info button in the toolbar below the List of Tables.

Make any field an expanded field, not just fields with Text format. The expanded fields will be concatenated together in the Expanded Fields Section of the Row Display. Go to the table settings of a table to select the expanded fields.

Hide the first section in the Row Display. The first section normally displays the field name and the first line of each field. If you hide it, and select some fields to be displayed in the Expanded Fields Section, all the lines of the selected fields can be displayed. This makes for easier browsing through the rows. Go to the table settings of a table to hide the first section in the Row Display.

The Expanded Fields Section now is sized better when multiple fields are expanded.

The SQL Console now has a "Functions" button that presents a window showing all the functions available in the app. Tap the function to see its description if it has one.

There is a Long-Presses section in the Help in the app info, describing the long-press shortcuts in the app.

The release date of the SQLite library used in the app is shown in the Diagnostics in the app info.

- In the "Tables Display" section of the App Info, the "Show Detail Button" option was removed as it was replaced with long press.

Even though this is a minor release, it is prudent to back up your critical databases and files before updating the app. To back them up, either use Dropbox or iCloud, or sync them with your computer.

IMPORTANT: This is a major release. If you have critical databases, you MUST back them up before updating the app. To back them up, either use Dropbox or iCloud or sync them with your computer.

IMPORTANT: Even though this is a minor release, it is good practice to back up your database files before installing an update, especially if they are critical. To back them up, upload them to Dropbox or iCloud, or share them to your computer using iTunes or AirDrop.

- In the SQL Console, favorites are now merged with the history, similar to the SQL History in the macOS version. To make a SQL command a favorite, tap the star adjacent to it. To only show SQL favorites, tap the star button to the left of the search bar.
- Execute multiple SQL statements in the SQL console. Separate them with semicolons.
- For Location field formats, the previous span of the map view is remembered.

Easier to Create SQL Views:
After executing a SQL query that returns results in the SQL screen, you can now create a SQL view from those results. You can also change the field formats of the fields when creating a view. This is a very powerful feature yet very lightweight, as it does not add any rows to the database, but lets you rearrange fields, select only a few rows, or reorder the rows.

Raw Field Format:
The new "Raw" field format lets you see the actual bytes in hexadecimal that are stored in a field in a row in the database. This is useful if you are having any issues with your data, or are storing binary large objects (BLOBs). They are only displayed and cannot be edited. To change their value use the UPDATE statement in SQL.

Dates and Times:
When a field with the Date or Time format is stored in General DB, by default it includes the time zone in +/-HHMM format at the end. Now you can omit that if you know you will always be in the same time zone (without Daylight Savings Time), or if you want to use UTC time. The original format is recommended however, as omitting the time zone causes ambiguity in dates and times.

There are some new built-in functions for converting fields in the Date and Time format of General DB to that which can be used by SQLite date and time functions. The following SQL statements can be executed in the SQL screen in General DB to see how they work:
SELECT utc2date('2020-01-01');
SELECT utc2time('2020-01-01 13:05:30');
SELECT date2utc('2020-01-01 -0400');
SELECT time2utc('2020-01-01 13:05:30 -0400');

Other Changes:
- Number of rows loaded for a Lookup Table can be increased in the app options. Only do this if you need to and have a fast device with a lot of memory.
- Specialized field views are available even if the table or view is read-only.
- SQLite 3.28
- Bug fixes

Include the + button so fields can be added in a new table.

Fix for error when altering a table that already has a view referring to it.

IMPORTANT: As this is a major release, it is imperative to back up your critical databases before updating! To back up your databases, either use iTunes or AirDrop to share your databases to your computer, or upload your databases to Dropbox.

Major Changes for the iPad User Interface:
The app's user interface on the iPad has been changed to more closely resemble that of the iPhone. This is not just to make them more consistent, but also to allow the larger iPhones to format fields horizontally in a row (set the "Row Format" option to "Horizontal"). When this app was first developed almost 10 years ago, the iPhone was 3.5" in size and the iPad was 9.7". Now some of the newer iPhones are much closer in size to th e iPad, so the change was necessary. Also, some of the views were changed to better use the larger screen-size of the iPad.

Lookup Tables:
A table or view can be designated as "Lookup" in its settings. Then it can be used as a data type of a field in other tables. The lookup table should normally have 2 fields. The first field is used as the key, and the second as the value. Selecting a lookup table field stores the key in the database, but displays the value in the Row screen and List of Rows screen. If a lookup table has only 1 field, then the ROWID will be used as the key.

Other Changes:
- The SQL Console is now accessible by tapping the lightning bolt button in the toolbar of the Tables and Files screen. It was previously in the app info or in the search bar area after selecting a table.
- A view no longer has to include the ROWID field. However, a view must be sorted on a unique key for all of its rows to be scrolled through, and it must be designated as such in its settings. If it is not designated as "Sorted on Unique Key", then scrolling through it is limited to the first 1,000 rows.
- The lightning bolt button in the SQL Results screen now prompts to create a view with the executed query. After you create a view, you can select it from the Tables list to see its rows. You can also change the format data type of the view's fields to display the data in a more readable format.
- The SQL Results screen now shows up to 1,000 rows
- Bug fixes
- SQLite 3.27.2

- Allows database file extensions of .db3 and .sqlite3
