- Native resolution support for iPhone 6 and iPhone 6 plus. - The example "Custom Simulations" CEML file is now hosted at a new URL. Any users that have the old default URL set will be automatically pointed to the new URL - https://dl.dropboxusercontent.com/u/5400542/example.xml. Performance: - A loading indicator now correctly appears in all scenarios when loading custom simulations from a CEML file. - To allow for more up-to-date iOS features in future releases, Loughborough Wave Lab is now only supported on iOS 7 or newer. Older versions of the app will continue to run on older versions of iOS.

New Features: ------------- - Adds animated tutorials to the Main screen, Configuration Settings screen, and Change Mesh Conditions screen which appear on first viewing of each screen to offer more information to the user and point out important parts of the application.

Bug Fixes: ------------- - Fixed a bug where custom CEML simulations where clipped slightly along the Y-axis, producing incorrect results when running CEML-based simulations. - Updated the loading screen for the iPad to the correct resolution. - The app has been optimised to have a much smaller file-size than previously - over 50% smaller!

New Features: ------------- - Loughborough Wave Lab is now optimised for multi-core devices, resulting in improved simulation speeds on those devices. - Re-designed UI in keeping with iOS 7.

New Features: ------------- - Improved simulation speeds on the iPad (4th generation) and iPhone 5. - Doubled the simulation resolution on iPad models with retina screens (3rd and 4th generations).

New Features: ------------- - Minor UI tweaks for increased usability

New Features: ------------- - During a simulation you can change the dynamic range of the display by pinching in & out. Higher dynamic range gives more variation (i.e. more yellows/reds) to a simulation that only has a few lower intensity point sources - Added several examples of electromagnetic phenomena built using the CEML configuration format to the default example CEML file being hosted - Configured the default example CEML file to automatically load on first launch of application when tapping the "Load Custom Simulations" button - CEML file URL can now be updated by tapping "Done" on the keyboard when editing, which saves time instead of having to tap "Update URL" after entering the URL - Optimised the look of all headings, buttons & text throughout the app for improved readability Bug Fixes: ------------- - Updated CEML examples URL as example simulations on some devices would not load due to a URL redirection change on the server hosting the example CEML file - Fixed a bug where the title on the CEML instructions page was editable on the iPhone

New Features: ------------- - Updated to support the new resolution of the iPhone 5 screen, offering an extended simulation area - Much improved simulation speeds when running on iPhone 5 devices - Returning to the main screen from the Configuration screen, and returning to the Configuration screen from the Change Mesh Conditions screen is now made clearer by text-labelled buttons - Optimised the button sizes on the main simulation screen when running on an iPad. Also included retina splash screen and tutorial graphics for the new iPad Bug Fixes: ------------- - Fixed minor bugs that were effecting the presentation of simulations on-screen, resulting in slight distortions to the aspect ratio of the image

New Features: ------------- - Revamped the entire user interface for an improved and consistent user experience across platforms - Simplified, concise instructions for using the app are presented when opening the app - When in multiple source mode, you can now "long press" on the screen to swap between drawing pulses and free-hand boundaries - Loughborough Wave Lab now uses CEML v0.4, offering improvements to configuring boundaries and point sources (see www.github.com/danielrbrowne/CEML for details) - Set default server address for custom simulations to point to the included CEML configuration file example - Added error checking for custom CEML simulations to ensure they will fit on the screen before attempting to display Bug Fixes: ------------- - Fixed a bug where continuous point sources could sometimes experience gaps in output when swapping modes

New Features: ------------- - Multiple Synchronised Point Sources Mode: Now, if you double-tap on the simulation, you can queue up multiple point source pulses and then when you're ready, double-tap again to resume the simulation! Multiple pulses can be defined either by tapping the screen for single pulses or by dragging your finger to create more complex sources. You can also define free-hand boundaries by changing the option in the "Change Mesh Conditions" screen and dragging across the screen in the same way. The phase relationship between placed point sources can be set by pinching in and out when in the Multiple Synchronised Point Sources mode. (Available when using the Gaussian and Sinusoidal Pulse modes). - Turbo Mode Button: Made clearer by changing the text to reflect which mode WILL be activated when the button is pressed, rather than which mode is CURRENTLY being used. - Significant simulation speed improvements in both Normal and Turbo simulation modes. Bug Fixes: ------------- - Specifying mesh dimensions different to the defaults within a CEML custom simulation did not result in correct mesh dimensions on screen. - The number of time steps that a CEML custom simulation will run for did not reflect the number specified in the user's CEML configuration file. - Gaussian point sources would repeat their execution even after completion when returning to the main simulation screen, which reduced performance when several are on screen at once. - Delayed point sources as part of a custom simulation would sometimes start at the beginning of the simulation rather than at the specified point.

New Features: ------------- - Turbo Mode toggle: switch between two different internal methods for calculating simulation behaviour, the original method using sequential processing, and a new method using vector maths. (Not available for iPhone 3G or 2nd gen iPod touch users. For more information if interested contact the developer) - Speed improvements on all devices: 25% increase in default simulation performance, and almost 10% increase in Turbo Mode performance on supported devices. (Speeds compared to the 3.0 release)

MAJOR RELEASE: Loughborough Wave Lab 3.0 ---------------------------------------- New Features: ------------- - Much improved simulation speed via optimisations to the internal mathematics. Average speed-up of 30% on all devices as compared to v2.5.3. - In-app purchase option added to enable further optimisations which result in a speed-up of 150% as compared to v2.5.3. (Not available for iPhone 3G or 2nd gen iPod touch users) - Revised the UI for adjusting the Mesh Loss Factor in the 'Change Mesh Conditions' screen to make it clearer how it effects the simulation. - Fully implemented support for CEML v0.3, which includes circular boundary objects. (see http://www-staff.lboro.ac.uk/~eldrb2/configcircles.xml for an example of usage) Bug Fixes: ----------- - Fixed a bug where point-sources could sometimes temporarily stop working when moving between preset simulation modes and the Custom simulation mode -Fixed a bug where custom simulations would sometimes not obey their configured start/stop times

New Features: ------------- - You can now change the loss factor of the simulation, which allows for energy in the mesh to die away, reducing complexity when used with reflective boundaries. Mesh loss is changed using the Slider in the 'Change Mesh Conditions' pane accessed from the Configuration panel (on app launch this defaults to 1, or no loss) Bug Fixes: ------------- - Fixed a bug where point-sources could sometimes temporarily stop working when moving between preset simulation modes and the Custom simulation mode - Fixed a bug where the wavelength values for the Waveguide and Double Slit modes where not shown on the Configuration screen when swiping to these modes and then visiting the Configuration screen

Bug Fixes: ------------- - Restored support for older iOS devices, following an error in a previous release which removed support for some devices. Notes: ------------- - Loughborough Wave Lab will now run on any iOS device running iOS 4.2 or later (app performance will differ depending on device). - Unsupported devices: original iPhone & original iPod touch

This is a minor update to address bugs that came to light following the changes to the CEML implementation in the recent 2.5.1 release Bug Fixes: ------------- - Fixed a bug where simulation mesh dimensions for the default modes became irregular after viewing a custom CEML simulation with mesh dimensions different to the defaults - Fixed a bug where it was possible for a gaussian pulse in progress to be cut short if changing simulation modes, producing undesirable dispersion effects in the mesh
