1.7.1

This release contains code refactoring, there are no functional changes.

• ::drawSprite inner protected method for U8g2 and AltSerialGraphicLCD versions of GEM (to unify code base with Adafruit GFX version);
• Splash struct renamed to GEMSprite (with Splash preserved as an alias for backward compatibility);
• Readme markup updates and minor cleanup.

1.7.0

• Support for preview callbacks that are called in edit mode when intermediate values of associated variable is changed;
• GEMItem::setPreviewCallback() and GEMItem::removePreviewCallback() methods;
• GEMPreviewCallbackData struct that contains preview value of a variable;
• Public GEMItem::getSpinner() method for getting range spinner (GEMSpinner) object;
• Method GEMSpinner::getOptionNameByIndex() made public, allows to get value of a spinner (as GEMSpinnerValue struct);
• Readme updated accordingly.

1.6.5

• Additional checks to fix null pointer dereference on empty menu page added (addresses #131 ).

1.6.4

• Bugfix for select/spinner arrows sprite overlapping option label when non-supported value of _spriteSize (> 2) is set through GEM_adafruit_gfx::setSpriteSize();
• title argument made optional in GEMPage constructor: now it is possible to call GEMPage menuPage to create menu page with empty title (instead of passing empty string, e.g. GEMPage menuPage(""));
• Optional loop setting for selects (GEMSelect) and spinners (GEMSpinner) added to allow endless loop through the options;
• Clarification on PlatformIO installation (contributed by @thijstriemstra);
• Readme updated accordingly.

1.6.3

• GEM_ITEM_LABEL non-interactive menu item that displays basic text information. Previously there were somewhat cumbersome ways to create simple label menu items with the use of readonly variables or buttons with dummy action, now it is possible to simply call GEMItem menuItemLabel("I am a text label!"); and non-interactive menu item with only title will be created;
• Readme updated accordingly.

1.6.2

• GEMPage::getItemsCount() method to get items count of the menu page;
• GEMItem::getType() and GEMItem::getLinkedType() methods to get type of menu item and type of linked variable;
• GEMItem::getParentPage() and GEMItem::getLinkedPage() methods to get pointer to parent and linked menu pages;
• Readme updated accordingly;
• Note on optional custom shields implementation for easier GEM development and prototyping of projects (available in wiki).

1.6.1

• Better support for menu traversing in user-defined callbacks (addresses #110);
• Public GEMPage::setCurrentMenuItemIndex() method for explicitly setting current menu item from sketch;
• Behavior of ::invertKeysDuringEdit() adjusted to affect GEMSpinner menu items (addresses #112);
• Readme updated accordingly.

1.6.0

• GEMSpinner menu item for increment/decrement of numeric variables;
• Public ::isEditMode() method that shows whether menu is currently in edit mode or not;
• Rotary encoder examples updated for more consistent detection of rotation;
• Readme updated accordingly.

1.5.4

• Support for setting sprites 'magnification' size (i.e. scale factor) for Adafruit GFX version via ::setSpriteSize() regardless of text magnification size set via ::setTextSize() method;
• Readme updated accordingly;
• Cleanup of redundant code.

1.5.3

• Addresses #96 and #97 error either all initializer clauses should be designated or none of them should be that appear if compiled for ESP32 boards with the most recently updated Boards via Arduino IDE;
• Minor Readme wording update.
