2.15.0

• Improved large subscription handling — adding or refreshing subscriptions with thousands of servers no longer spikes memory into the gigabytes or stalls the app
• Improved the tray icon's "Change server" submenu — for subscriptions with thousands of servers it now caps at 50 entries with a "Show all in main window" link instead of stalling on every server change
• Added a subscription reset action — when a premium subscription URL carries reset=1, Happ prompts to wipe local data (subscriptions, routing, logs, settings) before adding the subscription
• Fixed gigabyte-scale RAM use (and the system freezes or blue screens that followed) when pinging all servers on subscriptions that use balancer or observatory configs
• Fixed a duplicate dead tray icon left behind on Windows 11 after a previous Happ instance crashed
• Fixed flickering hover state on server rows when the cursor crossed nested controls like the sub-info button or edit chevron

2.14.0

• Improved regional-indicator emoji rendering so country flags in server descriptions show as inline icons on Windows instead of small uppercase letters
• Improved load-balancer ping so each outbound in a balancer JSON config is tested and the best result is reported
• Improved SOCKS/HTTP inbound authentication so username/password now applies to free subscriptions
• Improved error message for malformed subscription URLs, replacing the raw Qt error with a translated "Invalid subscription URL"
• Improved fragmentation setting clarity by renaming "interval" to "delay" across the UI and translations
• Improved Russian and Chinese translations for the "DNS from JSON failed" snackbar
• Added a new "via Proxy HEAD" ping mode alongside the existing "via Proxy GET"
• Added new noises-rand and noises-rand-range subscription parameters for randomized noise
• Fixed system-proxy mode on Windows when the HTTP inbound is disabled
• Fixed the EU country flag not rendering on Windows
• Fixed the server search field not clearing on full reset, which could hide newly-added subscriptions
• Fixed the right-click menu breaking for server names containing quotes
• Fixed the User-Agent read-only snackbar not showing in Subscription settings
• Fixed premium subscription parameters (such as new-domain) not applying on the first add of a subscription
• Fixed a spurious "Empty response from daemon" error and thread warning appearing on app shutdown

2.12.0

• Improved Windows installer now works fully offline — the Visual C++ runtime ships inside the installer instead of being downloaded during setup
• Improved Custom fragmentation and noise parameters from subscription share-links now apply consistently across VLESS, VMess, Trojan and Shadowsocks
• Improved Diagnostic reports now include your settings, the selected server's config, and routing state to make troubleshooting faster
• Fixed The app no longer silently switches your selected server when a subscription auto-updates

2.11.0

• Improved subscription parsing to read host, resolve address, fragment, and insecure settings from server response headers and body
• Added a setting for subscription request timeout (5–15 seconds, default 9)
• Added a toggle for the HTTP proxy inbound, now off by default
• Fixed connection reliability across rapid server switches, sleep/wake, and brief daemon outages
• Fixed Linux silently failing to launch after a previous hard crash
• Fixed TUN networking under heavy UDP load such as torrents: dropped connections from port exhaustion, default-direct traffic looping back through TUN, and UDP failing when proxy authentication was enabled
• Fixed Trojan, Shadowsocks, and SOCKS server names being dropped or truncated when they contained '#'
• Fixed overlapping text under the User Agent field in subscription settings

2.10.0

• Improved the server description to hide the "NONE" security tag and use a cleaner separator in the JSON tag
• Improved the xray core to version 26.3.27
• Improved sing-box TUN to honour the DNS-from-JSON setting the same way as Happ TUN
• Improved the inbound authorize screen to show SOCKS and HTTP credentials in Auto and From-JSON modes as copyable read-only fields
• Added an offline premium-status check so the app can verify premium immediately after a fresh install and for up to 30 days without reaching the server
• Added automatic disable of the OS system proxy on VPN connect when the per-app proxy feature is active, with a notification and the toggle flipped off persistently
• Fixed subscription expiry to show minutes when less than an hour remains instead of rounding up to the nearest hour
• Fixed a startup failure when a JSON subscription referenced unwritable log paths
• Fixed subscription URLs whose server name contains special characters like a trailing backslash failing to parse
• Fixed DNS-from-JSON not recognising xray's https+local:// DoH variant
• Fixed the User-Agent read-only indicator not responding to taps, and the interaction between the manual-block and change-user-agent premium parameters
• Fixed inbound authorize settings not refreshing after Reset Settings
• Fixed the inbound authorize mode dropdown being locked when premium metadata had pushed values, preventing manual override

2.9.1

• Update internal hosts

2.9.0

• Improved server list to show protocol/network/security (e.g. "VLESS / XHTTP / REALITY") under the server name by default
• Improved the "Insecure" subscription toggle — it no longer overrides per-server settings and now works without a premium subscription
• Improved local VPN security by requiring per-process SOCKS authentication so other apps on the machine can't probe the tunnel
• Improved DNS-from-JSON parsing to handle IP-in-URL DoH and surface the reason for any fallback in the subscription log
• Added a "random" autoconnect option that pings your subscription on app open and connects to a random alive server
• Added support for bypassing selected CIDRs from the tunnel (and forcing them direct in proxy-mode routing) via premium meta-params
• Added per-protocol inbound authorization for the local SOCKS/HTTP endpoints with Disabled/Auto/Manual/From-JSON modes, plus a copy button on the credential fields
• Added a configurable User-Agent for GeoSite/GeoIP downloads in the Routing section
• Fixed subscription fetch failing with "invalid hash" when the subscription URL uses a non-default port
• Fixed our own API domains being blocked from the Proxy routing section (they remain blocked from Block and Direct only)

2.8.0

• Improved server list scrolling smoothness with delegate reuse and async flag image loading
• Added Per-App Proxy "proxy-only" mode that routes only the selected apps through the VPN, alongside the existing bypass mode
• Fixed an occasional crash on the Servers screen when connecting or disconnecting
