Synthesis 8.1 has been released to NuGet. This is a minor feature release that also resolves an issue with the model provider caching in Synthesis 8.0.
@Html.DpiAwareImageFor() MVC helper method emits a
srcset along with the image that enables “retina images” served from the media library. To use it, you basically upload the image 2x (or 3x for the highest DPI devices) larger than it would normally display. Devices that support the higher resolution will automatically acquire the higher resolution version, and lower resolution devices will use the regular version.
Note that this is only for DPI-aware images. The more advanced forms of
picture that enable viewport-based features (‘responsive images’) are not supported at this time. Last I checked not well supported by browsers either.
Synthesis 8.0 depended on WebActivator to register its startup tasks. In 8.1, these have moved to the more Sitecorian
Synthesis.config file has been broken into three files:
Synthesis.config (global model configuration),
Synthesis.ControlPanel.config (enables the control panel page), and
Synthesis.Startup.config (enables on-startup sync checks and regeneration). This makes it much easier to deploy Synthesis to a Content Delivery server, as you can simply delete all but
Synthesis.config and be secure.
Synthesis 8.1 is a NuGet upgrade away. However to cover the new configuration changes, you do need to make a couple tweaks to an existing
<registerDefaultConfiguration value="true" />(Synthesis 8.0 only)
remove the whole
<synchronizationSettings>node in Synthesis.config (its values now live in
Synthesis.config(values now live in
add default configuration registration to Synthesis.config
<initialize> <!-- REGISTER DEFAULT CONFIGURATION If this processor is registered, the configuration values below for providers are loaded into a Default Configuration. This enables Synthesis to work out of the box if you do not need multiple configurations. For multiple configurations you may leave this active if you want to keep the default configuration and add your own on top of it, or remove it to register only your own configurations. Configurations are registered by calling ProviderResolver.RegisterConfiguration() - e.g. in more initialize pipeline processors. NOTE: Do not register multiple configurations that contain overlapping templates. --> <processor type="Synthesis.Pipelines.Initialize.RegisterDefaultConfiguration, Synthesis"/> </initialize>
if using the
optimizeCompilationssetting to speed up Sitecore 8 startup time, turn it off temporarily after the upgrade or clear your temporary asp.net files folder, because the helper structure changed slightly during the upgrade and the cached razor files will be invalid.
