feat: remove AggregationGetRequest class

[fern-api]

• The AggregationGetRequest class has been removed from the aggregation package. If your code references this class directly, you will need to update your implementation to use the new aggregation API structure.
• Several client classes and enum types have been removed from the SDK. The LatestheadlinesClient and SearchLinkClient classes are no longer available, along with various request parameter enum types like AggregationGetRequestSortBy, SearchGetRequestClusteringVariable, and others. Applications using these removed classes should migrate to the consolidated client implementations available in other SDK modules.
• The search similar functionality has been completely removed from the Java SDK. The AsyncSearchsimilarClient class and all its methods (get(), post()) are no longer available. Applications using these APIs must remove all references to search similar functionality.
• The search similar functionality has been removed from the SDK. The SearchsimilarClient class and its get() and post() methods are no longer available. Applications using these methods will need to remove those calls or implement alternative search functionality.
• The SearchSimilarGetRequest class has been removed from the SDK. Code that previously used this class for similar document searches will need to be updated to use alternative search methods.
• The SearchSimilarPostRequest class has been removed from the SDK. Applications using this class will need to migrate to alternative search methods or update their implementation to use the current API structure.
• The search similar functionality has been removed from the SDK. The SearchSimilarGetResponse, SearchSimilarPostResponse, SearchSimilarResponseDto, FailedSearchSimilarResponseDto classes and related types are no longer available. Applications using these types should migrate to alternative search methods provided by the API.
• The SimilarArticleEntity class has been removed from the SDK. If your code references this class, you will need to update it to use alternative article entity types or remove the functionality that depends on similar article data.
• The SimilarDocument class has been removed. Code using this type will need to be updated to use alternative document representations. The latestheadlines() method has been renamed to latestHeadlines(), and the separate searchLink() and searchsimilar() methods have been consolidated into a single searchByLink() method.
• The aggregation client methods have been renamed for clarity: get() is now countGet() and post() is now countPost(). Update your code to use the new method names. New SSE streaming support added for handling discriminated union types in Server-Sent Events.
• The aggregation methods have been renamed from get() and post() to countGet() and countPost() respectively. Additionally, the corresponding request and response classes have been renamed to include "Count" in their names (e.g., AggregationPostRequest is now AggregationCountPostRequest). Existing code using these methods will need to be updated to use the new method names and class names.
• New optional allLinksText parameter added to AuthorsPostRequest for enhanced content filtering. The theme, notTheme, and publishedDatePrecision parameters now accept String values for improved flexibility. Additional method overloads available for breaking news operations that accept RequestOptions.
• The robotsCompliant field has been removed from BreakingNewsGetRequest and BreakingNewsPostRequest. The theme and notTheme fields in BreakingNewsPostRequest now accept String values instead of enum types. The sortBy field in BreakingNewsGetRequest now uses the shared SortBy type instead of BreakingNewsGetRequestSortBy.
• The latest headlines client classes and methods have been renamed for consistency. AsyncRawLatestheadlinesClient is now AsyncRawLatestHeadlinesClient, RawLatestheadlinesClient is now RawLatestHeadlinesClient, and AsyncLatestheadlinesClient is now LatestHeadlinesClient. The get() method has been renamed to latestHeadlinesGet() and the post() method has been renamed to latestHeadlinesPost(). Update your imports and method calls accordingly.
• New optional parameters added to LatestHeadlinesGetRequest: sort_by for result ordering and all_links_text for searching articles by link anchor text content. The clustering_variable parameter now uses a shared ClusteringVariable enum type.
• The theme and not_theme fields in LatestHeadlinesPostRequest have been changed from enum types to string types. Existing code using Theme or NotTheme enum values will need to be updated to use string literals instead. A new all_links_text field is now available for additional link text filtering.
• The SearchGetRequest now accepts more flexible date formats through new From and To union types for the from and to parameters, supporting both date-time strings and plain text expressions. Added a new allLinksText parameter for searching articles by link anchor text content.
• The search_link package has been renamed to search_by_link with updated class names. All method names changed from searchUrl* to searchByLink*. The SearchPostRequest class now accepts string values for theme, notTheme, and publishedDatePrecision fields instead of enum types. A new allLinksText field is available for enhanced link filtering. Existing code using the search_link package or enum types for these fields will need to be updated.
• The searchlink package has been renamed to searchbylink. Classes SearchUrlGetRequest and SearchUrlPostRequest have been renamed to SearchByLinkGetRequest and SearchByLinkPostRequest respectively. Update your import statements from com.newscatcher.api.resources.searchlink to com.newscatcher.api.resources.searchbylink and update any references to the renamed classes.
• The content field in ArticleEntity is now optional (Optional<String> instead of String). Existing code that directly accesses getContent() will need to handle the Optional wrapper. The class no longer implements IArticleEntity interface, so code that depends on this interface will need to be updated.
• The Theme and NotTheme types have been renamed to ArticleEntityAuthors and ArticleEntityJournalists respectively. Existing code using these types will need to update import statements and class references to use the new names.
• The content field in BreakingNewsArticleEntity is now optional and returns Optional<String> instead of String. Code that previously accessed .getContent() directly must now handle the Optional wrapper (e.g., .getContent().orElse("")). The robotsCompliant field has been removed from the public API. The authors and journalists fields now use entity-specific types (BreakingNewsArticleEntityAuthors and BreakingNewsArticleEntityJournalists) instead of the generic Authors and Journalists types.
• Enhanced enum types (ClusteringVariable, NewsDomainType, SortBy) with visitor pattern support for safer handling of unknown values and future extensibility. Added null safety improvements to builder methods to prevent runtime exceptions when passing null collections or maps.
• The SDK now supports comprehensive logging configuration through the new LogConfig interface. Use the logging() method on client builders to configure debug output for HTTP requests and responses. RequestOptions now accepts query parameters for all endpoints, and search endpoints support the new all_links_text parameter.
• The SDK now includes a comprehensive logging system for monitoring HTTP requests and responses. Configure logging via LogConfig builder with custom log levels, loggers, and silent mode control. The system is silent by default and requires explicit configuration to enable output.
• New AggregationCountGetRequest class available for news aggregation with comprehensive filtering options including language preferences, geographic targeting, content classification, sentiment analysis, and entity-based filtering.
• The SDK now supports RequestOptions for customizing request timeouts, retries, and headers on breaking news and sources methods. Two new client modules are available: SearchByLinkClient for finding articles by link or ID, and LatestHeadlinesClient for retrieving the most recent news headlines.
• New builder methods additionalProperty() and additionalProperties() are now available on SourceInfo, SubscriptionResponseDto, and TimeFrameCount for handling additional API response fields.
