for 2.0.0-M2

remove:
- [REMOVED] @MemberGroupLayout
- contributed domain services (use mixins instead)
- org.apache.causeway.applib.clock
  - Clock singleton
- SwitchUserService
- AbstractFixtureSusa
- org.apache.causeway.core.runtime.services.eventbus.adapter.EventBusImplementationForGuava

- [DONE] org.apache.causeway.applib.services.memento  (19 usages found)
  - [REMOVED] MementoService.java - remove entire service (previously to support view models, but now @ViewModel and JAXB)

to change:
- automatically wrap domain services (perhaps behind a config property)
- automatically infer \@Programmatic for all \@DomainService(nature=DOMAIN)


support for legacy implementation of UrlEncodingService
- as an automatic fallback; has changed to use with compression by default.

inline paraname8 from incode platform

[DONE] remove causeway-core-wicket-applib 
- [DONE] contains only WicketDeveloperUtilitiesService, which is hidden anyway and seems to not be required.

update .xsd for layout, make render optional and deprecated.    
   
- deprecate FixtureScripts service with view to removing from applib ... the framework provides an implementation by default
- get rid of automatic initialization of fields (perhaps behind a config property)
- deprecate the Apache Causeway' DateTime classes for removal in the future) ... and probably all of the custom value types, subclasses of Magnitude
- merge metamodel and runtime
- remove *Installer

move ContentMappingServiceForCommandDto and ContentMappingServiceForCommandsDto from applib.conmap to applib.services.conmap.commands

[DONE] CausewayContext:
- [REMOVED] resetLogging()

TitleFacetViaAnnotation may not work if on a field, due to DN lazy loading.


[REMOVED] remove AbstractService from applib.
[REMOVED] remove AbstractViewModel from applib.

OTHER STUFF:

PublishingServiceInternalDefault

not thread-safe:

    boolean suppress;

    @Programmatic
    @Override
    public <T> T withPublishingSuppressed(final Block<T> block) {
        try {
            suppress = true;

link:https://issues.apache.org/jira/browse/CAUSEWAY-743[CAUSEWAY-743] - @NotPersistable annotation


*************************************************************************

PROPOSE TO RETAIN:


Below is the code currently deprecated in the applib, but I propose to retain even in 2.0.0 (on the grounds that a replacement for them is not fully designed):
org.apache.causeway.applib.adapters  - custom value type support


org.apache.causeway.applib.annotation

    Encodable.java - entire annotation, part of custom value types support
    Parseable.java - entire annotation, part of custom value types support


org.apache.causeway.applib.fixtures  - "legacy" fixture support package ... by and large can use FixtureScripts (though not sure if there's feature parity in all cases)
    AbstractFixture.java
    AbstractFixtureSusa.java
    BaseFixture.java
    CompositeFixture.java
    DateFixture.java
    LogonFixture.java
org.apache.causeway.applib.fixtures.switchuser
    SwitchUserService.java
    SwitchUserServiceAware.java


org.apache.causeway.applib.services.command
    Command.java  - methods that pertain to the execution of the command and its completion (for that, use Interaction) [suggest we retain for now]
        getCompletedAt()
        getException()
        getResult()
        getStartedAt()
        next(String)
        setCompletedAt(Timestamp)
        setStartedAt(Timestamp)
        flushActionDomainEvents()
        peekActionDomainEvent()
        popActionDomainEvent()
        pushActionDomainEvent(ActionDomainEvent<?>)  (

    MemberGroupsLayout.java - retain
