Release Notes By Version

1.0.15 (Current in pom.xml)

What changed:

• Refactored SchemaExtractionStep into orchestration-only flow and moved schema-heavy calculation into provider contract.
• Added provider computation model:
  • ConvEngineSchemaComputation
  • ConvEngineSchemaResolver#compute(...)
  • ConvEngineSchemaResolver#sanitizeExtractedJson(...)
  • ConvEngineSchemaResolver#mergeContextJson(...)
• DefaultConvEngineSchemaResolver now owns sanitize/merge/completeness/missing-fields/missing-options behavior.
• Clean provider override model for consumers:
  • consumers can register their own ConvEngineSchemaResolver bean
  • selection honors higher precedence via Spring @Order.
• Centralized runtime input-param keys into ConvEngineInputParamKey.
• Centralized fixed audit stages into ConvEngineAuditStage.
• Added dynamic audit-stage helper for resolved-intent source:
  • ConvEngineAuditStage.intentResolvedBy(...)
• Centralized payload map keys into ConvEnginePayloadKey.

1.0.14

What changed:

• Added optional ce_rule.state_code to scope rule execution by state.
• Runtime matching contract:
  • NULL -> applies to all states
  • ANY -> applies to all states
  • exact value -> applies only when session state matches (case-insensitive)

1.0.13

What changed:

• Split audit DB persistence into strategy classes (IMMEDIATE and DEFERRED_BULK) selected by factory at runtime.
• Kept ce_conversation_history persistence synchronous on every eligible stage to keep prompt {{conversation_history}} deterministic.
• Allowed ce_audit to run deferred-bulk while preserving conversation history availability.
• Added _meta persistence toggle via convengine.audit.persist-meta.
• Removed framework-bundled default application.yaml; consumer now owns convengine.* config.

1.0.12

What changed:

• Added audit metadata enrichment for every stage:
  • _meta.inputParams: runtime/session-mutated parameter view
  • _meta.userInputParams: API-origin parameter snapshot
• Added controller-ingress deep-copy isolation for userInputParams so nested request objects are immutable from later runtime mutations.
• Extracted deep-copy logic into a reusable engine helper:
  • com.github.salilvnair.convengine.engine.helper.InputParamsHelper

1.0.11

What changed:

• Added cross-database persistence hardening across SQLite, Postgres, and Oracle:
  • JSON column binding now uses Hibernate JSON JDBC typing for jsonb paths
  • audit persistence now uses dialect-aware JSON/timestamp JDBC binding
• Added SQLite legacy runtime normalization at startup:
  • normalizes epoch timestamp text rows into parse-safe datetime text
  • normalizes legacy BLOB conversation_id rows into canonical UUID text
• Refined sticky intent semantics:
  • sticky skip now applies only during active incomplete-schema collection
  • outside schema collection, intent can re-resolve for semantically new turns

1.0.10

What changed:

• Added ce_rule.phase execution model:
  • PIPELINE_RULES
  • AGENT_POST_INTENT
• Added runtime rule-phase filtering so:
  • RulesStep executes only PIPELINE_RULES
  • AgentIntentResolver post-intent pass executes only AGENT_POST_INTENT
• Added session/input metadata for rule-source awareness:
  • postIntentRule, post_intent_rule
  • rule_phase
  • rule_execution_source, rule_execution_origin
• Added post-intent rule invocation after accepted agent intent.
• Added sticky intent continuity controls:
  • IntentResolutionStep.STICKY_INTENT (ce_config, default true)
  • skip intent re-resolution when intent/state are already resolved
  • added audit stage INTENT_RESOLVE_SKIPPED_STICKY_INTENT
  • explicit reset/switch/force signals still allow re-resolution
• Updated prompt variable exposure:
  • prompt extra now receives all inputParams keys
  • includes runtime/system-derived keys set via session.putInputParam(...)
• Hardened stream startup validation and condition timing behavior to avoid false-positive startup failures.
• Updated SQL generation docs/prompts to include ce_rule.phase contract.

1.0.9

Commit: 695ef79

What changed:

• Enhanced experimental SQL generation API output for consumer import workflows.
• Added SQL-by-table response structure to make generated output easier to inspect and apply incrementally.
• Added zip packaging support with per-table SQL files plus combined seed.sql.
• Updated docs and SQL generation guidance for clarity and alignment with current runtime model.

1.0.8

Commits:

• a2daeec core release bump and transport/audit foundation
• 57a2faa async audit dispatch + deferred flush controls (post-bump enhancements on same line)
• c5c665f typed step API via EngineStep.Name
• 0c2c557 rule action rename to GET_SCHEMA_JSON

What changed in detail:

• Added streaming transport stack:
  • SSE and STOMP/WebSocket support
  • consumer-configurable stream mode
• Added audit event plumbing:
  • AuditEventListener extension point
  • stage broadcast path for streaming UIs
• Added advanced audit controls:
  • async dispatch workers
  • queue/backpressure policy
  • deferred bulk persistence + flush triggers
• Strengthened step extension API:
  • string-based step matching replaced by typed EngineStep.Name
  • safer EngineStepHook contracts (supports/beforeStep/afterStep/onStepError)
• Renamed schema action contract:
  • GET_SCHEMA_EXTRACTED_DATA -> GET_SCHEMA_JSON
  • aligned resolver/session access semantics

1.0.7

Commit: 05f9077

What changed:

• Schema extraction and intent resolution refinements
• additional agent resolver controls/flags
• better handling of schema-aware intent decisions

1.0.5

Commit: 6f6033d

What changed:

• stronger propagation of input parameters across turns
• better task action resolution in rules/action path

1.0.4

Commit: 48aae75

• improved rule-driven transition behavior
• richer audit emission around intent/rule flow
