⚠️ Configuration databases are versioned. Export BackUp Settings from the old version, then import them into 2.5.

2.5 turns “extract a value from one packet and reuse it” into saved packet extractors, and upgrades proxy TCP unpacking into ordered, multi-rule, bidirectional incremental framing.

• Packet Extractor List: save variable groups and scopes. Variables can be constants, packet extractions, or expressions referencing other variables; integer, floating-point, bytes and text are supported
• Packet extraction: read at an absolute offset or relative to the filter match, then parse by type, byte order, signedness and text encoding. Socket and proxy-session values can have a TTL
• Dynamic filter replacement: a modify cell can bind an enabled extractor variable and output format. A matching filter captures first, then writes the current value into the packet. Runtime values live only in memory
• Extractors support ordering, copy, import/export and backup; MCP can inspect and maintain their configuration under its confirmation policy

• Ordered multi-rule list: manage rules in Hook Settings → UnPack. Each rule has a name, enabled state, direction, header and length field; order is the priority for the first match
• Bidirectional incremental framing: Proxy-Mode TCP only. Requests and responses keep their own fragments; each complete frame independently goes through filters, capture and forwarding. It does not apply to UDP or Inject Mode
• Safe resynchronisation: partial headers and frames survive across receives; an invalid length advances one byte and resynchronises without blocking traffic. Both frame and fragment limits are 4 MB
• Rules participate in settings backup, use .upr for import/export, and can be read or atomically saved through MCP

• Global display text: display preferences persist and you can set the global UI text size and primary text colour
• Focus List: a new button on Inject- and Proxy-Mode packet-list toolbars hides the statistics, lower pane and dropped-packet notice so the packet table gets more height; the status bar and common actions stay available
• Backup, firewall, mapping and hook settings have refined layouts and validation
• MCP grows to 147 tools, including packet extractors and unpacking rules
• An injection-attach failure now reports as a failure instead of a successful attachment

⚠️ The configuration database is stored per version. Export BackUp Settings from the old version, then import it in 2.4.

Proxy Mode receives a new process-interception path and expanded mapping; 2.4 also adds reusable decoders, Smart Decode and a rebuilt encode/decode workbench.

• Built-in mihomo core: select or manually name processes in Process Settings; TUN routes their traffic into WPE, and draft settings apply together on Save
• Structured HTTP: HTTP traffic is shown directly as requests and responses, while non-HTTP traffic stays as TCP
• TCP connection mapping: route an entire TCP connection by host/IP and port while retaining capture, logging and TCP filters

• HTTP mapping matches a complete request header and can serve a local file or route to another address
• HTTPS mapping provides root-certificate creation, trust, export and management for enabled mappings; HTTP/1.1 local-file and remote mapping are supported

• New decoder list: save an algorithm, key, frame rules and scope as a reusable recipe; enable, disable, copy, reorder, import and export .dec files
• Algorithms and frames: XOR, AES, DES, RC4, XXTEA, text charsets and structural viewers for Protobuf, MessagePack, BSON, AMF and FlatBuffers; length frames support 1/2/4-byte fields, byte order, fixed headers and data offsets
• Scope and Smart Decode: limit a decoder to TCP/UDP/HTTP/WebSocket and request/response direction; right-click a packet to use one decoder or intelligently try every enabled matching decoder. Multiple packets process in the background with progress and cancellation
• Encode/decode workbench: combines quick XOR, AES-CBC, Base64, UTF-8 and Protobuf structure inference, and switches between quick work and saved decoders. The standalone XOR page is removed

• Packet lists and details gain decode entry points; the Proxy status bar reports kernel and TUN state live
• Decoding only runs at the user's request, never changes the original packet and never enters capture, filter or forwarding hot paths

⚠️ Configuration databases are stored per version, so 2.3 does not pick up your 2.2 data: export everything from the old version with BackUp Settings first, then import it into the new one.

This release connects WPE to an AI client on the same machine — letting the AI read and write WPE's existing features on your own PC. The proxy side also picks up several device and concurrency related abilities.

• MCP Settings: a new entry on the start page (the number of available tools is shown on the right) holding a master switch and an "MCP operations need confirmation" switch — see Chapter 8 for connecting an AI client such as VS Code
• What it can do: an MCP-capable AI client on this machine can look at packets, connections, logs, accounts and proxy runtime state in conversation, and perform actions on filters, accounts, proxy settings, send lists, robots, warehouses, auto-store, single-packet editing, injection, Process Settings, the firewall, mappings, WPC servers and backup export / import. The settings page lists every tool, grouped by proxy / inject / packet / filter / send / robot / warehouse / settings
• Status lamp: the status bar now shows MCP state — grey is stopped, amber is waiting for confirmation, green is running
• MCP log: the System Log gains a fourth tab recording every tool call
• Emergency stop: one command halts running senders and robot executors (it only stops, it never starts anything)
• While you are still on the start page, the AI can pick Proxy or Inject Mode for you

• Allow WPC clients only (requires authentication to be on): once enabled, a plain SOCKS5 client is refused even with the right credentials, and the refusal goes into the System Log
• Device identity: the client list gains a Device column — WPC connections show in green (hover for the client version and the OS it reported), plain clients show a dash
• Connection details: WPC's persistent control connection is labelled as such instead of looking like a broken connection
• Maximum connections: the dialog now shows a per-connection memory estimate and this machine's ceiling, and refuses a value above it with a written reason
• Fixed the reply source address for UDP coming in through WPC, which removes the packet loss game UDP suffered

• The left navigation can be collapsed into an icon rail
• Inject Mode's title bar gains Back to start page
• Instance Settings turned from a full page into a sectioned dialog matching the other settings, with a new Default folder button
• The client list's location column can be dragged wider, and the sort arrow in table headers is no longer skewed
• IP geolocation no longer errors out on IPv6 addresses and domain names

⚠️ This is a big update. Before downloading and using it, export and back up all your data from the old version with BackUp Settings. Once the new version starts, it automatically removes the old version's program.

This release replaces the whole interface: every page and dialog in both modes was redesigned, with seven languages and light / dark themes. Inject Mode is more stable and touches the target program less, a long list of problems was fixed, and everyday operations are noticeably faster.

• Brand new interface: 14 pages and 12 dialogs in Proxy Mode, 11 pages and 7 dialogs in Inject Mode, all redesigned in the same palette as this site
• Ships as a single-file launcher, WPE64 2.2.exe (inside WPE64 v2.2.zip, with a SHA256 checksum file): just double-click; the first run unpacks it and every launch checks and repairs the files
• Two-part version numbers: this release is 2.2
• Seven interface languages: Simplified Chinese, Traditional Chinese, English, Japanese, Korean, Vietnamese and Russian, switched instantly
• Dark / Light / Follow system themes plus a "scan line" toggle, all behind the gear icon in the title bar
• The title bar gained Always on Top
• The 13 exported file types now have icons in Explorer; they can be cleared from Preferences → File icons

• Nothing is drawn inside the target program any more: only the capture part runs there, while the interface and data stay in WPE's own window — lighter on the target
• Inject Mode now has the same 11 pages and 7 dialogs as Proxy Mode
• Three ways to pick a target: process, window or file, plus a "quick inject" for the last one
• Fixed: injecting some 64-bit programs could crash the target
• Fixed: auto-store did not work in Inject Mode

• Fixed: UDP Force Proxy did not work
• Fixed: TCP connections outside the "specified ports" list were neither proxied nor listed
• Fixed: saving the process settings with the default configuration could cut the selected process off the network; settings are now checked and the connection tested before saving
• Fixed: spaces in the port list stopped some ports from working
• Stopping the proxy or quitting now releases the captured processes; the name-based list is remembered
• The process list no longer shows WPE itself

• Entering Proxy Mode and opening the account list are much faster, especially with many accounts
• Fixed: WebSocket packets captured over HTTPS were missing from the totals and traffic; the cells now read "HTTP / WS request · response"
• Fixed: statistics could occasionally come up short with many connections at once
• Auto-clear now drops only the oldest rows, keeping the most recent N instead of emptying the whole table; its switch moved onto the data page toolbar
• Warehouses gained a size cap (5000 by default, oldest dropped), and large warehouses save faster

• Fixed: hex search found nothing without spaces or in lowercase
• Fixed: robot key combinations were pressed wrongly
• Fixed: delays and send intervals ran longer than set, and "random delay" was not random enough
• Fixed: packets captured over HTTP / HTTPS / WebSocket were skipped when sending
• Fixed: a loop count of 0 sent nothing, and pressing Start without a system socket gave no hint
• Fixed: continuous send in the packet editor took a long time to stop
• Fixed: the log said "completed" when a robot or send had failed

• Fixed: the firewall could error under many connections, and "auto-clear expired IPs" now clears on schedule
• The lists can be edited while the firewall is off, with a note that they are not in effect yet
• Fixed: the same IP could appear several times in an account's login history
• Fixed: an account with a connection or device limit of 0 could not connect; the minimum is now 1
• Backup now includes warehouses, auto-store rules, WPC servers and WPC notices; fixed remote mappings not being exported and imports appending instead of replacing; "encrypt" with an empty password now shows a message
• A failed backup export is reported clearly, with the reason in the system log

• Text compare redesigned: inserting or deleting bytes marks only what really changed instead of flagging everything after it
• Duplicate finder lists the longest shared fragments first, each only once, with its share
• XOR calculator updates live, accepts text keys, and adds a "data A ⊕ data B" mode
• Encoding converter laid out in groups per encoding, with clearer byte-order labels
• Fixed: pasting a large block into the encoding converter closed the program
• Fixed: data extraction only read the first session from a Charles file
• Remote console redesigned: works well on phones, never shows a stale page after an upgrade, accepts passwords with colons and non-ASCII account names, and has stronger login and anti-forgery protection
• Fixed: the remote console's "proxy log" tab showed the system log

• The WebView2 runtime is no longer bundled: Windows 11 has it and Windows 10 usually does; if it is missing the app guides you to install it
• Components used only by the old interface were removed, so the program folder is leaner
• ⚠️ Settings are stored per version: 2.2 does not pick up an older version's settings. Export them from the old build via Backup settings first, then import into the new one
