version 2.0.3

• date: September 5, 2026
• Added: "Number of Languages" selector (3–20) at the top of the General Settings tab, shown faded/disabled with a "Coming Soon" overlay; it will be enabled by the upcoming QML Premium addon.
• Changed: General Settings tab now groups the HTML lang attribute and hreflang fields per language (Primary Language / Secondary Language rows). Option keys unchanged; stored settings are unaffected.

version 2.0.2

• date: September 5, 2026
• Fixed: silenced Plugin Check prefix warnings on the uninstall.php helper variables and the so_qmp filter names (false positives; the sniffer derives its expected prefix from the plugin name).

version 2.0.1

• date: September 5, 2026
• Added: filter-aware accessors for tier limits (so_qmp/tier, so_qmp/max_languages, so_qmp/max_page_mappings) in preparation for the Premium addon.
• Changed: the html lang attribute is now driven by the plugin's page mappings instead of page hierarchy; pages removed from the mapping fall back to the primary language.
• Fixed: unmapped pages no longer output self-referencing hreflang and x-default links.
• Fixed: mapping rows beyond the stored "Number of Pages to Map" are ignored on the frontend and deleted from the database when the count is reduced.

version 2.0.0 major refactor OOP

• date: August 19, 2026
• Note: Major refactor. Minimum WP raised to 6.2. Minimum PHP raised to 8.2. No breaking changes to stored settings; existing so_qmp_* options are preserved.
• New: OOP architecture under the SOWP\QuickMultilingual namespace with split class files in src/.
• New: Canonical URL output for mapped pages (<link rel="canonical">), removing WordPress core rel_canonical on those pages to prevent duplicate tags.
• New: Activation guard deactivates the plugin and shows an admin notice when PHP < 8.2 or WordPress < 6.2.
• Changed: Minimum PHP requirement raised from 7.0 to 8.2.
• Changed: Minimum WP requirement raised from 5.0 to 6.2.
• Changed: Page mapping loop now follows the tier limit (MAX_PAGE_MAPPINGS = 4) instead of a hardcoded 4, preparing for the Premium tier.
• Developer: Lite/Premium roadmap; tier limits centralised in Config. Settings page markup kept compatible with the existing admin.js (.nav-tab, .so_qmp-tab-content, #so_qmp_number_of_pages, #page-translations-table, .page-mapping-row).

version 1.5.8

• date: August 19, 2026
• Fixed: HTML lang attribute now correctly switches to the secondary language based on the page hierarchy instead of unreliable URL string matching.

version 1.5.7

• date: August 18, 2026
• Fixed: Escaped all admin option outputs and dropdowns to satisfy PHPCS/PCP checks and prevent unescaped output vulnerabilities.
• Fixed: Added explicit casting with absint() for stored page IDs (for example so_qmp_language_folder_page) to ensure integer values are used where expected.
• Fixed: Added translators comment for the "Page %d" label to clarify the placeholder meaning.
• Changed: Replaced hardcoded script version with SO_QMP_VERSION and bumped asset versioning to improve cache-busting for admin.js and admin.css.
• Fixed: Added a targeted PHPCS ignore for an admin-only exclude usage in wp_dropdown_pages() to address a WordPress VIP performance warning (settings screen; excludes a small, bounded set of pages).
• Changed: Prefixed uninstall.php file-scope variables to follow plugin naming conventions and remove PCP naming warnings.
• Notes: No breaking changes. Behaviour is unchanged; changes are defensive and to satisfy code-quality checks.
• tested up to WP 7.1
