[Unreleased]

[26.9.1] - 2026-09-16

Added

  • Win64 packages for Delphi 12 and 13 in the DPM specification. DPM derives the platforms a package supports from its build and design entries rather than from targetPlatforms, so declaring Win64 there is what dpm install -platforms=Win64 needed (#87)
  • An OCL workbench demo, and a Database menu that lets the demos switch engine with their preconditions checked first
  • A generated class reference converted from the Bold 4.0 help file
  • A README for every example, recording which ones no longer run as shipped
  • Conway gained a usable interface: load, save, draw and help

Fixed

  • Bold's HTTP transport sends and receives its payload as bytes rather than characters, so non-ASCII content survives the round trip (#99)
  • An invalid TBoldObjectList cast in cxGridBoldSupportUnit that crashed any DevExpress grid bound to a list of types
  • Conway no longer crashes on a board containing blank lines
  • The ASP demo client's main form, which had been a byte-for-byte copy of the data module's form since the 2020 source release and could not open

Changed

  • The ASP example is ported off IBX to FireDAC with SQLite, so it builds with nothing installed; its README now documents hosting the ISAPI extension under IIS
  • The OCL Explorer is ported off DevExpress onto TBoldGrid, taking the executable from 26.7 MB to 10.6 MB
  • The GUI uses Segoe UI 9 pt throughout
  • Releases ship the Win32 design BPLs only, with the reasoning recorded in the release checklist (#87)
  • Bold is listed on the TMS Smart Setup community registry; installing with Smart Setup and with DPM is documented (#87)
  • Documentation is consolidated: ROADMAP.md is the single roadmap, CHANGELOG.md is included into the docs site rather than duplicated, and the landing page explains what Bold is for

[26.9.0] - 2026-09-06

Added

  • collect(role) evaluates in the persistence layer: TBSS_collect is implemented and installed, so self.child->collect(parent) and the implicit self.child.parent translate to SQL instead of falling back to in-memory evaluation (#96)
  • IBoldDatabase.ReleaseAnotherDatabaseConnection releases a connection obtained from CreateAnotherDatabaseConnection (#92)
  • The UniDAC adapter tests compile through a stub-unit DebugUniDAC build configuration, so UniDAC is never required; they run on SQL Server and SQLite, against the vendored UniDAC 10.4 on Delphi 12 or UniDAC 11 on Delphi 13 (#89)
  • Adapter-neutral persistence scenario tests run on every adapter (#88, #80, #89); end-to-end tests drive TBoldDbCopy and the database validator threads (#92, #93, #94)
  • BOLD_TEST_ENGINE selects the test database engine without editing UnitTest.ini; UnitTest\run_matrix.ps1 runs the adapter x engine matrix (FireDAC and UniDAC on SQLite and SQL Server) with one summary table
  • UnitTest\sync_gui_dpr.ps1 generates the GUI runner's unit list from the console runner, so TestInsight runs the whole suite (#84)
  • DPM package specification, packed and published to the public feed at https://delphi.dev as bero.BoldForDelphi for Delphi 11, 12 and 13, plus a Boss manifest and a release checklist (#87)
  • TMS Smart Setup definition (tmsbuild.yaml) and version.txt, so tms install bero.boldfordelphi builds and registers the design package for Delphi 11, 12 and 13; submitted to the community registry (#87)

Fixed

  • Data corruption on FireDAC: with MultiRowInsertLimit = 1, PMCreate wrote the second new object's attribute values into the third and later objects saved in one UpdateDatabase, because the per-row reset cleared a parameter snapshot instead of the query's real parameters (#88)
  • UseBatchQueries was broken on both FireDAC and UniDAC (#80); it is now refused on engines where batching is unverified instead of failing at run time (#95)
  • Undo: the redo value space was orphaned when undoing a block with no changes, and DoUndoInTransaction used a block after freeing it (#86)
  • UniDAC: cached queries leaked when a connection wrapper was destroyed (#90); CreateAnotherDatabaseConnection created a TUniConnection nobody freed (#91); GetDatabaseError raised its own exception for providers without an error-code table, hiding the real database error (#98)
  • TBoldDbCopy and the database validator dropped the extra connection wrappers they obtained (#92); validator worker threads were never freed (#93)
  • TBoldDbCopy failed silently on FireDAC: Prepare ran before the parameter types were known, worker exceptions were swallowed, the row-count query leaked; failures are now logged and reported through Errors (#94)
  • FetchFromClassList fetched every invalid single link of the other-end class one by one, one SELECT each, when deriving a multilink from a current class extent; it now falls back to the single database query and leaves invalid members alone (#97)
  • The design packages could not be installed from the IDE after LIBSUFFIX AUTO: a leftover LIB version in the project files made the IDE look for dclBold370.30.bpl while the compiler produced dclBold370.bpl (#87)
  • The two ignored FetchRefetch tests are rehabilitated and pin the classic DbFetchOwningMember path; the suite has no ignored tests (#83)
  • Three TestBoldOclEvaluation tests assumed the creation order of unsaved objects in a class extent; they sort first
  • The Delphi 11.3 design package was built without a version resource: its Debug/Win32 configuration overrode VerInfo_IncludeVerInfo to false
  • The 26.8.1 Delphi 12.3 package had lost NoObjectSpaceTransactions again (the define restored for #85 was dropped by the version-stamping commit the same day); all three packages now declare it in the same project group (#85)

Changed

  • Design packages are named by compiler through LIBSUFFIX AUTO (dclBold280.bpl, dclBold290.bpl, dclBold370.bpl); the Delphi 12.1 CE package project is retired (#87)
  • CanEvaluateInPS answers True for collect(role), where it previously answered False on every engine (#43, #96)
  • Test suite at 2182 tests (2182 passing, 0 ignored, 0 failed); code coverage 58.5%

[26.8.1] - 2026-08-16

Added

  • Parameterized ID-list SQL for SQL Server: MaxParamsInIdList raised to 500 (#75), multilink fetch and PMDelete use parameterized lists with explicit ParamCheck (#76), and IN-lists are padded to fixed bucket sizes so the plan cache is reused (#77)
  • Bound parameter values are now written with the SQL log, rendering NULL as NULL and blob payloads as a placeholder; an optional UnitLog-backed sink is selected by the new BOLD_LegacyLog / BOLD_UnitLog defines in Bold.inc (#82)
  • IBoldQuery gains ParamCount and Param[] (#82)
  • Unit-level helpers GetSharedString / GetSharedAnsiString in BoldSharedStrings, and BoldNamesEqual / BoldAnsiEqual / BoldStrAnsiEqual in BoldUtils (#82)
  • Benchmarks for id-list SQL covering bucket collapse and the plan-cache bound (#79)
  • First test coverage for EmbeddedSingleLinks stamping on the DbFetchOwningMember path (#83)
  • setup-tests.ps1 and UnitTest/README.md to make first-time setup work without hunting for dependencies

Fixed

  • Orphaned read transactions on the shared connection: Clear did not close, so releasing a query to the cache left its transaction open, and ExecSQL / Open discarded ownership of a transaction the query itself had started. Row locks then blocked other work until the connection was recycled. Fixed for both UniDAC and FireDAC (#81)
  • SetEmptyValue left null non-nullable attributes null and raised on valuesets (#74)
  • SubscribeToHandle no longer dereferences a variable list rebuilt during teardown (#61)
  • The Delphi 12.3 design-time package had lost NoObjectSpaceTransactions, compiling a different TBoldSystem interface than the other three packages (#85)
  • UnitTestGUI project could not build: missing Code\Main in the unit search path (#84)
  • Documentation named Delphi 13 as Athens instead of Florence, pointed at package folders that never existed (packages/Delphi30/), and advertised a seven-month-old release as current

Changed

  • Release tags follow Year.Month.build with no zero padding, so they parse as semantic versions for dependency managers such as Boss
  • Both test runners compile the default configuration; the Attracs define was removed from UnitTestGUI.dproj so console and GUI runs test the same code (#84)
  • Version information normalized to 26.8.1.0 across all four design-time package projects, which had drifted to four different values
  • Test suite at 2165 tests (2163 passing, 2 ignored)

[26.8.0] - 2026-08-03

Added

  • 7 XML roundtrip tests for OLW node streaming (NodeList, Operation, TypeNode, ListCoercion, Member, Literals, OclCondition)
  • 5 XML roundtrip tests for BoldCondition streaming (28.7% → 99.4% coverage)

Fixed

  • 4 memory leaks in OLW XML streamer ReadObject methods — CreateObject allocated internal lists that were orphaned when ReadObject overwrote field pointers (#34)
  • Add try-finally blocks for Bindings cleanup in TBoldXMLOCLConditionStreamer
  • Standardize Pascal casing and fix method name typo
  • Correct field name casing from flist to fList in TBoldOLWNodeList

    • InitializeIndirectLinkFields, InitializeDirectLinkFields, InitializeTimestampFields
    • SystemHasDirtyObjects, DoPreChangeIfNeeded
  • Removed C++ support from BoldUMLModelValidator (#16)
  • Refactored TBANumeric.GetStringRepresentation to extract common logic (#19)
  • Refactored TBABlob validation (#14)
  • Code coverage improved from 28% to 40%

Fixed

  • String columns ignoring AllowNull when using EmptyStringMarker (#11)
  • 64-bit ACCESS_VIOLATION in grid and edit controls (#9)
