All notable changes to this project will be documented in this file.

v1.26.0-rc.1 - 2026-10-04 (production acceptance pending)

Changed

• Hot path: build cache identifiers from a memoized per-site/group hashed prefix plus rawurlencode($key) instead of serializing a lookup key on every call; identifiers are unchanged (verified against Keyspace::id()). Look up global groups through a set, skip closure creation for untraced client calls, memoize command name casing, test runtime presence with isset() first and return early from remember-group and prefetch-recording checks. Runtime acceptance and benchmarks remain pending.
• PhpRedis 6.0/6.1 (no getWithMeta()): read values on direct connections with one atomic pipelined MULTI GET+EXISTS instead of GET followed by a plain MULTI, which PhpRedis sends one command per round trip (5 round trips per miss before, 1 now). Stored false and WRONGTYPE handling are unchanged; verified with php/igbinary and none/lzf/zstd/lz4 on PhpRedis 6.0.2 and 6.1.0. Cluster, Relay, replicated and Sentinel connections keep their existing read path.
• Send MULTI..EXEC blocks of write-only commands inside a pipeline on native PhpRedis clients (one round trip instead of one per command), normalizing boolean replies; transactions containing reads keep the plain MULTI path. Skip UNWATCH after an executed EXEC, which already clears every WATCH.
• Prefetch: skip rewriting the request’s metadata record (a watched multi-command transaction) while the record read at boot already covers the recorded keys for at least half its TTL.
• Analytics: claim the periodic Redis INFO sample with a raw SET NX EX 3 (redis-sample) instead of get()/set() of last-sample, so measurements no longer credit their own hit/miss and runtime-cache metrics.
• Confirm absolute EXPIREAT deadlines for key-growth hourly metadata and completed-scan history inside the existing watched transaction. Preserve SET’s finite EX fallback and reject unconfirmed expiry without replay. Delay/expiry-failure validation remains deferred.
• Require PHP 8.2+ and PhpRedis 6.0+ consistently in bootstrap, plugin, drop-in and Composer.
• Start a cold v2 namespace with lossless prefix/site/group/key encoding and group hash tags.
• Use pinned WATCH/MULTI/EXEC for split alloptions and bounded prefetch metadata, without conflict replay.
• Reuse up to eight clean direct transaction sockets per owning connection for Cluster and cache-enabled Relay. Preserve per-transaction Cluster discovery and discard sockets on errors, changed settings or unavailable native state checks; publish observation deltas only.
• Use a single watched primary for persistent counters; return false and invalidate local memory on conflicts or unconfirmed writes.
• Do not replay ordinary Sentinel writes or unknown/raw commands; suppress native retries during the send and retain existing read retries.
• Default group cleanup to incremental SCAN; delete at most 500 keys per command.
• Bound prefetch metadata to one hour, 256 keys per request and 1,024 request records per site by default.
• Bound memory logs and saved commands to 500 records and report omitted entries.
• Move redis-cli passwords to the child process environment; require CLI 5+ for password use.

Added

• Owner-approved opt-in historical TTL evidence: shared request budgets, a separate capped site/hour record with absolute retention, confirmed-write histograms and explicit completed-hour CLI/REST/admin reports. Existing Insights schema and cache policy are unchanged; see TTL-HISTORY.md. Final acceptance remains pending.
• Extend the existing real HTTP profile with bounded confirmed-write TTL evidence: requested/capped/sent seconds, histogram and explicit coverage; distinguish runtime-only writes and preserved counter expiry. Cover single/bulk, alloptions and remember publication without new Redis probes or hourly schema changes. Correlate bulk replies with queued IDs. Final validation remains deferred; see HTTP-PROFILE.md.
• Owner-approved portable configuration presets (woocommerce, membership, publishing, multisite), explicit-field precedence, strict bounded manifest validation and exact group TTL caps before jitter. Add read-only CLI list/show/export/import/diff and current-site REST/Insights previews; report the cap in key diagnostics and TTL review. No automatic application, TTL rewrite or measured performance claim. Final tests remain deferred; see CONFIGURATION-PROFILES.md.
• Opt-in key-growth diagnostics: bounded HMAC key/pattern observations and hourly HLL estimates; explicit fenced live SCAN with completion/topology checks; bounded history and conservative growth comparisons; wp redis key-growth, scoped REST/admin actions and opt-in doctor guidance. Source review only; runtime/backend/performance acceptance remains pending. See KEY-GROWTH.md.
• Read-only TTL/persistence evidence in Cache Insights: aggregate completed-hour activity across callers of each group, identify usage patterns, show current policy context and suppress directions on errors/overflow or incomplete site scope. Add admin/JSON/REST output and wp redis insights --ttl-review with bounded results. Per-key lifetime/reuse measurement and numeric TTL recommendations remain unimplemented; no settings change or runtime acceptance is claimed.
• wp redis profile <url> (source 2026-10-05): one real same-site anonymous GET, HMAC one-use ticket, captured-primary handoff, forced request-only collection, bounded per-call timing/size events and signed temporary report; JSON/table and explicit partial/unavailable outcomes. Exclude forced samples from hourly Insights. Final runtime/backend/performance validation remains pending; see HTTP-PROFILE.md.
• Sampled Cache Insights (source 2026-10-05): 2% request sampling by default, bounded component/group attribution, logical payload coverage without reserialization, site/hour counters on the owner-approved WATCH path, bounded report reads, six review rules, existing-library admin charts, protected REST and wp redis insights. No runtime or performance acceptance is claimed; see CACHE-INSIGHTS.md.
• wp redis why <key> --group=<group> --format=json|table with current scope/policy, memory flags, primary type/TTL/hash-marker and optional remember-lease metadata. Explain hypothetical write TTLs with –ttl, distinguish observed evidence from unknown history, omit cache values/raw identities and return distinct error/conflict exit codes. Final CLI/backend validation is pending.
• Separate opt-in ocp_remember() API with bounded primary-side leases/waiting, ownership-checked publication and caller-only fallback in protected scopes. Default-empty stampede_groups enables two-phase lease invalidation for mutations and lease-first cleanup; preserve existing codecs, TTL caps/jitter, hash merging and WordPress signatures. See STAMPEDE.md for deployment and partial-EXEC limits.
• Drop-in migration settings page with current/replacement fingerprints, private signed backup downloads, short-lived install confirmation and guarded restoration through WordPress’s filesystem API. Require core POST nonces, cache and plugin-installation capabilities, plus a network super administrator on multisite; retain existing lifecycle/CLI behavior.
• Optional ttl_jitter percentage (0-100, default 0): randomly shorten finite TTLs after existing limits, independently per bulk key and for split alloptions, while preserving counter and metadata expiry policies.
• Current-request performance panel and existing-library historical charts.
• Permission-checked site/network cleanup preview exposing only key fingerprints.
• CLI doctor JSON/table reports and explicit preview-first legacy namespace cleanup.
• Source/drop-in/harness provenance and fixture/configuration matching for benchmark comparison.

Fixed

• Preserve full management group scans while converting incomplete/invalid reads to a generic REST error. Bound each memory pipeline to 500 keys, inspect the captured transaction client’s error state and distinguish missing memory observations from zero-byte measurements.
• Correct group response context filtering; expose non-atomic scan/missing-memory metadata without changing the successful list shape. Prevent overlapping UI scans, keep the selected memory mode stable during a request and label scan counts/memory as estimates. These source changes are untested.
• Keep Query Monitor output tied to its matching collector, preserve another extension’s replacement output, and keep the commands menu accessible without its parent cache menu. Guard optional backtrace and Members registration APIs.
• Show omitted log counts and retained-only command totals in Query Monitor, distinguish general log entries from Redis commands, tolerate incomplete raw-command log context and escape rendered command labels. Verification is deferred at the owner’s request.
• Repair the ApexCharts CDN fallback: use the correct WordPress tag filters, attach the existing SHA-512 integrity hashes to their exact CSS/JS source, and preserve other tag attributes. Keep the bundled assets, pinned CDN version and older WordPress fallback. Source change only; verification deferred at the owner’s request.
• Reject unsupported or unconfirmed namespace resets before recording a successful flush or writing reset metadata; convert backend PHP errors to the existing logged false result.
• Guard optional native ATOMIC/SCAN constants, align the diagnostic transaction property with its existing constructor check, clarify Insights counter types, and register return-valued WordPress hooks as filters while retaining callback identities.
• Correct WP-CLI option paragraph boundaries so format validation does not reject hours, group names, timeouts or event limits.
• Catch the actual ConnectionException in Relay CONFIG/SLOWLOG helpers; preserve false on connection errors, unrelated exceptions and no replay. A focused regression reproduced the prior uncaught exception.
• Honor WordPress’s found flag in wp_cache_remember() and wp_cache_sear(), preserving cached false values without invoking the callback. These helpers do not acquire leases or wait.
• Preserve active raw codec scopes across Sentinel primary/replica discovery and direct Cluster/Relay transactions; restore captured settings on both retired and replacement connections, including nested scopes and partial failures.
• Reject unsuccessful initial serializer/compression option setup and close the affected socket before serving cache operations.
• Separate drop-in ownership from inherited compatibility: automatic/admin enable, update and deactivation, plus CLI disable, preserve files whose product name and URI do not match this project’s bundled drop-in.
• Refresh header/stat caches before ownership decisions and after successful mutations; expose protected files in the widget, dashboard, Site Health and doctor. Explicit CLI enable –force remains available for deliberate replacement.
• Restore captured serializer/compression options after raw callbacks, including nested calls and partial setup failures; reject unsuccessful restoration, attempt to close the affected client and preserve the first error.
• Unwind raw-mode scopes on the original primary/replica connections even when another node fails or discovery replaces the connection references.
• Count error records omitted at the request buffer limit and expose them separately from logger omissions in cache info, diagnostics and the performance panel.
• Include omitted errors in overview/Site Health totals, reset the counter on fresh cache initialization, and escape Site Health error messages as text.
• Preserve the original transaction/callback failure when UNWATCH, DISCARD, mode inspection, routing restoration or client close also fails.
• Reject failed transaction cleanup instead of reporting success, and attempt to close uncertain native connections without replay.
• Normalize bare bracketed IPv6 Cluster seeds without appending an extra port.
• Preserve merged alloptions data after bulk writes and invalidate memory on failed hash updates.
• Keep prefetch metadata in the site that requested each key.
• Verify prefetch record/index membership before crediting eviction space; repair detected inconsistencies even when both containers have equal counts.
• Reject failed or malformed prefetch membership reads before executing writes; preserve no-replay behavior after partial EXEC failures.
• Reject failed prefetch cardinality reads before queuing writes; skip metadata reads after the request key budget is exhausted.
• Validate prefetch record expiration and reject invalid incremental deletion counts.
• Abort alloptions writes before EXEC on fresh existence-command errors, invalid TTL replies or a hash missing at the TTL read.
• Validate cleanup replies, propagate failures, and preserve scoped cleanup with the full group setting.
• Show database-wide effects of full cleanup in management UI and previews.
• Label global/network preview scopes correctly and show the effective cleanup method and atomicity.
• Keep doctor reports structured when client capability or drop-in inspection fails; never echo private exception details.
• Include failed-command wait time and align performance reporting sources.
• Remove the counter’s TTL-dropping SET fallback; use conditional KEEPTTL or remaining-TTL PX on older servers (see migration limitations).
• Resolve named Cluster profiles before launching redis-cli.

Acceptance

• Key diagnostics, native TYPE normalization and the shared deterministic jitter-range calculation have source review only. CLI/help/exit codes, metadata/error/side-effect contracts, input/integer limits, real topology/Relay behavior and performance checks remain final-phase gates.
• The approved separate remember API and mutation/cleanup integration have source review only. Syntax/static checks, option/false/null/hash/TTL contracts, 20-process races, partial EXEC/lost replies, real topology/Relay/Valkey checks and five-repeat performance measurements remain final-phase gates. No earlier passing report validates this addition.
• Drop-in ownership and management changes are source-reviewed only; focused fixtures and real WordPress lifecycle/UI/CLI verification are deferred to the final test phase. Header identity is not proof of file integrity or protection against concurrent external writers.
• The latest codec-restoration changes have source review only. Per the owner’s current workflow, tests remain required but will run together after the development changes are complete; earlier passing reports do not validate this patch.
• The error-buffer reporting update passed 38 PHP unit cases and 152 assertions, including a 24-check bounds/reporting scenario. Ten source/template/test files passed syntax checks. Scoped PHPStan reported eight findings reproduced on the preceding commit, with no new findings; it is not a clean static-analysis result. The earlier real WordPress run predates this update.
• After owner authorization, PHP 8.3.0/PHPUnit 9.6.37 passed 37 local regression cases and 148 assertions; one real WordPress/Docker feature test was skipped.
• Regression fixtures cover the approved v2/counter contracts and reject truncated local HTTP responses through either observed PHP error path.
• Eleven changed PHP files passed syntax checks; nine related production files passed PHPStan level 5 with zero errors.
• A subsequent fresh WordPress 6.8.3/WooCommerce 10.2.2/PHP 8.3.35/PhpRedis 6.1.0/Redis 7.4.2 run passed six real integration scripts and the lifecycle suite; the previously skipped contracts.php scenario passed. All 37 regression cases passed in the Linux container as well.
• The prefetch correction passed the 37 regression invocations, seven real integration scripts and lifecycle suite in a new fresh fixture. Its new real Redis scenario passed 50 checks for bounds, seeded metadata inconsistencies, TTL, serialization and site/data isolation. Partial EXEC failure injection remains covered by deterministic clients; added Redis read overhead is not yet measured.
• Runtime/drop-in bytes were checked against 187 source files. The disposable fixture’s containers, network and volumes were removed after the run.
• Real Cluster/Sentinel/TLS/Relay, two-customer checkout, 20-process/million-key, browser and baseline/candidate performance gates remain open.
• Prior revision results do not establish v2 correctness, backend parity or the five-percent performance gate.
• See MIGRATION-v2.md for cold rollout, legacy cleanup, and rollback into an unused namespace.
