2026-09-10​

Added​

• Java SDK packages on Maven Central (io.toggly)

Changed​

• SDKs apply initial targeting context (identity, groups, and claims) before the first definitions fetch so the first evaluation is already targeted (JavaScript, iOS, Android, React Native, Remix, Nuxt, Docusaurus, Python, and Go)

2026-09-06​

Added​

• Usage and business metrics on Node, Go, Java, Python, Ruby, Rust, PHP, Next.js, Nuxt, Remix, Docusaurus edge, and Cloudflare Worker SDKs

Changed​

• Cloudflare Worker integration fetches flags from definitions.toggly.io

2026-09-04​

Added​

• Ambient evaluation context for Node, Next.js, Nuxt, and Remix server helpers (getGroups / getClaims without passing context on every call)
• Segment and request-context filter parity on Java, Python, Ruby, Rust, and PHP SDKs

Fixed​

• Next.js no longer keeps the previous user's identity after switching users
• Remix ambient evaluation context no longer dropping empty fields
• SDKs reject signed definition payloads that are HTTP 200 but contain an error

2026-09-03​

Fixed​

• React TogglyProvider permanently destroying the client under Strict Mode
• Next.js Edge evaluations missing evaluation context
• Open-ended Time Window filters aligned with Definitions

2026-09-02​

Changed​

• Browser and mobile Feature APIs use Feature + negate: disabled UI is a separate Feature block with negate instead of a disabled-content slot
• Server SDKs download signed definitions and evaluate targeting locally (including entity context)
• Next.js server helpers expose entity context on each check

2026-09-01​

Added​

• SDK cheat sheets for every platform

Documentation​

2026-08-28​

2026-08-23​

Added​

• Entity-gate evaluation on Android, iOS, and Flutter

2026-08-21​

Fixed​

• PHP SDK HTTP client failing to load (TogglyHttpClient)

2026-08-20​

Added​

• Entity and page context targeting across SDKs — Context Property filters evaluate per check (order, product, account) rather than on the user session

2026-08-19​

Added​

• Contexts: Dashboard view for named entity kinds and properties used in targeting
• Application context catalog that trusted SDKs can register at startup

2026-08-18​

Added​

2026-08-10​

2026-07-12​

Fixed​

2026-07-11​

Added​

• Configurable maxCacheKeys LRU limit for identity-keyed client caches
• Server-side SDKs persist signed definition snapshots so restarts can recover without a network round-trip

2026-07-07​

Added​

• FeatureGateBuilder: Keep gated UI mounted and drive enabled state (styling, disabled controls) across client SDKs, with local-gate reactivity

Fixed​

• Flutter SDK anti-rollback: Signed definitions with an equal timestamp are accepted (same payload re-served); only strictly older timestamps are rejected. On rollback the SDK keeps cached flags/variants instead of resetting to flagDefaults
• Flutter SDK setIdentity / setContext: No longer wipe persisted cache when switching users; in-memory state is cleared and other users' persisted entries are kept for switch-back

Changed​

• Flutter SDK definitions revision: ETag persistence is scoped per evaluation identity (user, groups, claims). TogglyRevisionCacheProvider methods now take an identity parameter (breaking for custom cache backends). Official cache packages migrate legacy revision keys on read

2026-07-05​

Changed​

• Definitions Worker WebSocket sync: Connect sends sync with definitions revision; clients pass ?rev= and skip HTTP when unchanged. flags-updated includes etag; signing-key-updated notifies signing key rotation
• Unified definitions revision: Single etag for HTTP If-None-Match, X-Definitions-Revision, and WebSocket sync across all client SDKs
• SDK live updates: Debounced refresh, exponential WebSocket reconnect backoff, and revision persisted in cache providers (Flutter, React Native, browser SDKs)

2026-06-16​

Fixed​

• Segment-based Microsoft.Targeting evaluation on the Definitions edge worker (Audience.Users lists, percentage rollout aliases, and indexed parameter coercion)
• Identity URL encoding for targeting filters in JavaScript and Flutter client SDKs

2026-06-15​

Fixed​

• Flutter SDK pub.dev publishing and migration to the maintained isar_community storage fork

2026-06-14​

Fixed​

• Redis memory growth from unbounded unique-user tracking keys (daily and monthly cleanup jobs, proactive stale-key deletion, and TTL repair)

2026-05-30​

Changed​

• Flutter SDK: Memory-only by default with opt-in pluggable cache providers (secure storage, disk, SQLite, and Isar companion packages)
