v20.0

• Add Live Java Scratch Pad: eval arbitrary Java in the attached JVM
• Add JFR analysis tab/window: visualize captured recordings in-app

v19.0

• Fixed concurrency issue with fetching of live classes
• Live profiler side tab

v18.0

Add JStudio Live: attach to a running JVM

New :live-agent and :live-client subprojects

• Attach to a running JVM and browse its loaded classes
• Patch & Continue: recompile the current class and live-redefine it, grafting only the edited method bodies so the member set is preserved
• Capture runtime-defined classes into the project
• Heap instances, static fields, and thread/deadlock views

v17.0

• Add Dual view: linked bytecode/source panes
• Clickable "N usages" lenses on class, method, and field declarations; open Find Usages (View ▸ Usage Counts toggle)
• Shared XrefQueryService (one xref build + filter for lenses and Find Usages); class usages scoped to type references, not member accesses
• Navigate/locate declarations via decompiler spans; regex kept only as Hide-Annotations fallback
• Find Usages selection skips string/char literals and prefers the real member-access/call token
• Recompiling a class invalidates the xref database

v16.0

• Version bump 16.0
• Fix NPE scrolling the debugger source tab before the window is laid out

v15.0

• Fixed a few bugs in decompiler with reconstruction/recovery of VARARGS
• Migrated Query engine over to YABR
• Extract non-UI logic out of com.tonic.ui into sibling packages (util/model/event/service/deobfuscation/script/simulation); cli/plugin now depend on those, not ui
• Find Usages now jumps to the exact call site in source and selects the referenced name
• Bytecode debugger: tabbed Bytecode/Source view; source tab tracks the executing line and supports breakpoints (gutter click or context menu)
• Fix breakpoints binding to the wrong method when viewing callees in recursive mode

v14.0

• Fixed a bug with query DSLs IN sets
• Updated some stale data in README
• Query DSL md docs

v13.0

• Rewrite Query Explorer DSL as a composable matcher algebra
