PHP 0.8.0

This release consolidates the never-tagged, never-published 0.7.2 preparation
with official opt-in SPSS Frontend 0.3 support. The previous public release is
0.7.1; there was no 0.7.2 release.

Added

• Explicitly selected official SPSS Frontend 0.3 using the existing strict
  request/parser/binder/compiler pipeline; Frontend 0.2 remains the default.
  Support comments, dictionary-order TO and grouped commands, NOT and comparison
  aliases, finite open RECODE ranges, and ordered typed ADD VALUE LABELS.
• Check all 90 effective official cases against the unchanged specification pin,
  inherited Plan 0.1/0.2 objects and hashes, and native SQLite in-place provenance
  and identity. All 20 implementation CI jobs passed at
  22e261842e538188aea281896c578c5f3d1e38b7, including the service matrix
  (run). Declare
  Frontend 0.3 officially conformant while retaining its opt-in capability field.
  The final 0.8.0 release commit still requires full CI before tagging.
• Use precedence comparisons, NOT, AND, OR; parentheses override. Compilation
  is pure over request metadata: callers supply the current ordered dictionary
  and typed value labels; the compiler does not read the database. No
  STRING/DELETE, schema extension, Plan 0.3 or In-Place 0.3 support is added.

Fixed

• Preserve finite binary64 precision in SQLite case values and compression bias,
  and in affected multiple-response counted-value metadata writes.
• Fail imports on SQL errors even when the supplied PDO uses silent or warning
  mode, restoring the caller's error mode afterward. Reject caller-owned active
  transactions before import mutation.
• Finalize SQLite/PostgreSQL import audit success inside the native import
  transaction, so finalization failure rolls back the attempt. Retain the
  MySQL/MariaDB/Dolt ownership-scoped cleanup and finalization compensation.

Performance

• Send PostgreSQL and MySQL/MariaDB/Dolt case INSERTs in bounded prepared batches,
  respecting parameter/packet budgets and preserving preflight-valid oversized
  singleton rows, case order, NULLs, strings and numeric precision.
• Load canonical and legacy export dictionary children and set members with
  dataset-scoped grouped queries instead of per-variable/per-set queries.
  Export remains database-read-only and observes fresh metadata on every call.

Existing import/export call forms, dependencies, specification pin, database
support claims and catalog schema remain unchanged. Catalog preparation and
ownership checks are retained; this release requires no new migration.

OpenStatSpec PHP v0.7.1

Patch release updating the SPSS codec dependency.

• Updated installed and exact CI-tested openstatspec/spss-sav from 3.0.3 to 3.1.1.
• Aligned engine identity, capability declarations and conformance assertions.
• No adapter API, specification pin or database-support changes.

Validation: local Composer validation, lint, style, PHPStan and PHPUnit checks passed against pinned specification v0.5.0. Full GitHub PHP 8.4/8.5 and PostgreSQL, MySQL, MariaDB and Dolt integration matrices passed. Production dependency dry-run and distribution archive inspected.

Full changelog: v0.7.0...v0.7.1

OpenStatSpec PHP v0.7.0

Database-read-only export and predictable Dolt support

• SAV/ZSAV export reads authoritative normative metadata directly: no compatibility-catalog rewrites, operation/fidelity audit records, initialization or migration, including failure paths.
• Output is published only after successful temporary-file writing. Existing destinations survive writer failure. Export-after-transformation preserves named formats, measurement levels and valid defaults for new variables.
• Default Dolt writes support exactly the tested 2.2.2 and 2.2.3 versions without external declaration files. Other write versions are rejected; positively identified Dolt read-only exports are independent of the write-version gate.
• Selects openstatspec-database-io-v1 from released specification v0.5.0, commit 864e84479f554b8ee250ffed44c4dfb963750d4a.

Migration

Breaking: SpssExportResult::operationId and its constructor argument are removed. Import operation IDs are unchanged. Initialize/upgrade the catalog explicitly with SpssAdapter::migrateCatalog() on a write-capable deployment connection; export refuses unready catalogs instead of repairing them.

Breaking: the former broad Dolt 2.2.x write range is narrowed to the two exact tested versions. Injected SPSS writers receive a temporary path and must use the Dataset's target format, not the temporary filename extension.

composer require openstatspec/php:^0.7

Release commit: 8d15c184c36b8bc3091ac938da0be47fceb312fa.
Reviewed with defect fixes; full PHP 8.4/8.5 and SQL-service CI, real SELECT-only Dolt round trips/failure preservation, and Composer checks passed. Plan/Frontend/Binding 0.1/0.2 claims remain unchanged; optional 0.3 contracts are not implemented.

OpenStatSpec PHP v0.6.0

OpenStatSpec PHP adapter v0.6.0.

• Claims Transformation Plan 0.1/0.2, SPSS Frontend 0.2, and In-Place Transformation 0.1/0.2 conformance.
• Pinned to OpenStatSpec specification v0.3.0 at cd8f198c68b849eb8ed018a894670a0904c2181d.
• Removes openstatspec-transformation-plan-v1, SPSS STRING, and DELETE VARIABLES.
• MySQL, MariaDB, and Dolt require pre-provisioned and catalogued targets. Dolt commits remain caller-owned.
