Changelog

Recent updates, additions and removals across Z Tools.

This page tracks every meaningful change to Z Tools — new tools launching, existing tools being rewritten, data refreshes after game patches, language additions, policy changes, and bug fixes large enough to mention. Newest releases are at the top.

The site updates roughly every two weeks during active development, and again whenever a Last Z: Survival Shooter patch changes the underlying data (hero skills, building costs, research badges, event rotations). Patch-driven updates are tagged Update; net-new features and pages are tagged New.

For real-time release notes, the What's New ticker at the top of every page shows the last few items. For the official roadmap of what's planned next, see the About page.

Live this week

v3.2

Alliance Spaces leave beta. Nothing about the spaces already running changes — this is the label coming off something that has been carrying real alliances for months.

  • New Alliance Spaces are out of beta

    Ten alliances across ten states now keep their guides, notices, notes and shared calendar in a space, and it has been steady enough for long enough to stop calling it an experiment. It is still free, and it stays free.

    Development has not stopped — the difference is the promise attached to it. The parts an alliance leans on are settled, and anything that would disrupt a space gets an email to its owners, admins and editors first rather than turning up as a surprise. The terms set out the notice periods that go with that.

  • Update The directory renders in full before JavaScript runs

    The public directory was built from a skeleton listing a single alliance, with the other nine appearing a moment later once the database answered. All ten are now in the page as it is served, so the grid, the state filter chips and the count are right on first paint instead of shifting under you. The live reconcile still runs on top, so a space created or deleted since the last build is still reflected without waiting for a rebuild.

  • Update Clearer about who is responsible for what is in a space

    A space's contents are written by its own members, and the Spaces page and terms now say plainly that Z Tools does not write, check or endorse them and is not liable for them. There is also a straightforward warning: a space can hold links its members typed, we do not scan them, and you should not download files from a link you do not trust. Uploads into a space can only ever be images.

v3.1.1

A data and usability release for the Research Trees tool. Saved progress — on this device or synced through myZ — carries over untouched: every existing tree and node keeps its identity, and this was verified against every synced account rather than assumed.

  • New Shooter Training — the tenth badge tree

    The tree that unlocks after 100% Field is now in the planner: 12 nodes, 1,357,180 badges, full stats and dependencies. The tool now covers every technology in the game whose nodes cost research badges — 10 trees, 173 nodes, 5,594,364 badges to max the lot.

  • Update Badge cost corrections

    A handful of costs were corrected — the two ten-level Hero Training nodes had their top levels wrong by 340 badges between them, and eleven Army Building costs previously marked TBC are now confirmed numbers. The few deep-endgame values not yet confirmed stay honestly marked TBC rather than being guessed at.

  • New The trees now look and navigate like trees

    Dependency lines connect every node to what it unlocks, in the tree’s own colour, turning green as each prerequisite is maxed and highlighting around whichever node is open. Every node’s detail panel has Requires and Unlocks buttons that jump straight to the related node, the arrow keys walk the tree (Escape closes the open panel), and previous/next buttons switch between all ten trees without going back to the overview.

  • Update Easier to read, on any screen

    The tree sits on a proper panel instead of floating over the page artwork, nodes and open panels are clearly layered, and everything — including the new dependency lines — is measured to stay pixel-accurate on phones, while scrolling, and in all 18 languages.

v3.1

Two big additions, both marked beta: they work and they are live, but they are new enough that details will still change and the odd rough edge is likely. Nothing about them is required — every tool and every wiki page works exactly as before without signing in to anything.

  • Beta myZ — an optional account

    myZ is the new button at the top right of every page. Make an account and the progress you build up in the tools follows you between devices — tick research nodes on your laptop and they are already ticked on your phone. There is no password: you type your email, we send you a code, and that is the whole sign-in. Signed in, the button opens a menu with your account and any alliance spaces you belong to.

    It is entirely optional. Every tool works the same without it, saving to the browser you are using exactly as it always has. You can see everything stored for you, download it as a file, or delete it outright from your account page.

  • Beta Alliance Spaces — a private space for your alliance

    An alliance space is somewhere your alliance keeps its own guides, notices, notes and a shared calendar. Spaces are private: only members of that alliance can see one, and they are not indexed by search engines.

    You can now ask for one from the Spaces page. Tell us your in-game name, state, alliance tag and rank, and we check it by hand against the alliance in game — usually within a couple of days. If your alliance already has a space you are added to it; if it does not, we create one and make you its owner. You get an email either way.

    Play in more than one state? Ask once for each — a separate account in a separate alliance gets its own space, and they all appear together under myZ.

  • New Notices, a calendar and pinning inside a space

    Alliance spaces can now post notices — short, prominent messages that sit at the top of the page, with an optional expiry date so “hive moves at 19:00” disappears by itself once it is over. There is a shared calendar for events, shown in each member’s own timezone rather than whoever wrote it. Anything can be pinned to keep it first, and work-in-progress is clearly marked as a draft so it is never mistaken for the real thing.

  • New Roles, and members who can manage themselves

    Everyone in a space has a role — owner, admin, editor or viewer — and the page tells you what yours lets you do rather than leaving you to guess why a button is missing. Admins can change roles and remove people, and anyone can leave a space themselves from their account page. Every change is recorded, so an alliance can see who changed what.

  • New Emails that actually arrive

    Ask for a space and you get a confirmation; your alliance’s owners and admins are told someone has asked, so a stranger cannot be added on our say-so alone. When it is decided you get an email either way, with the reason if it was not approved. If you are ever removed from a space, you are told rather than finding it has quietly vanished.

  • Update Known gaps while these are in beta

    The new spaces and myZ screens are in English only for now — the rest of the site remains translated into all 18 languages, and these will follow. That is on the list.

v3.0
  • New A proper contact form

    The Contact page now has a form instead of just an email address. Pick what your message is about, write it, and attach up to three screenshots — a picture of a wrong number is usually quicker than describing it. Anything larger can be sent as a WeTransfer link. Contact has also been added to the main menu so it is reachable from every page.

  • New Redesigned support panel

    The little tab on the right-hand edge of every page is now a slide-out panel with three clear choices: donate, report incorrect or missing content, or get in touch. Reporting a data problem takes you straight to the contact form with the subject already filled in.

  • Update Research trees without data are now clearly marked

    Ten of the nineteen trees on the Research Trees planner do not have their badge costs recorded yet. They previously looked identical to the finished ones and opened to an empty tree. They are now greyed out with a “Data coming soon” label and can no longer be opened, so it is obvious at a glance which nine trees are ready to plan with. They still appear in search.

  • Update A consistent look across every page

    Panels, cards and page headings now share one design throughout the site. The About and Donate pages have the same panelled layout as the policy pages, and the Tools page heading now matches the wiki and alliance spaces. Tool pages also had their long explanatory text moved below the tool itself, so the tool is the first thing you see.

  • Update Everything new is available in all 18 languages

    The contact form, the support panel and the new research labels have been translated into every supported language rather than left in English. Game terms such as Last Z, HQ and Lucky Rose stay in English by design.

  • Update Alliance content tidied up

    Now that Alliance Spaces is a directory open to any alliance, references to one specific alliance have been removed from the general pages. They remain where they belong — in the wiki guides and on that alliance’s own space. Old links still work.

  • Update Seven new gift codes — and every active code now shown together

    Added INPLAINSIGHT, WELCOMELZNF, WELCOMELZNV, THANKU250KCOM, WELCOMELZFB, WELCOMELZX and WELCOMELZDC. The Gift Codes page previously featured only the single newest code; it now shows every active code at once, each with its own copy button, plus a “copy all” button for redeeming the whole batch in one session.

  • New 12 new wiki guides added

  • Update Translations refreshed across all 18 languages

  • Update Site-wide SEO & social-share improvements

  • New Lucky Rose Number Tracker — new tool

Includes a suggested 14-step unlock path for non-whale HQ 30 accounts.

  • New Wiki and alliance hub split into individual pages

    Every wiki guide (43 articles) and the alliance Megahive Rules now have their own dedicated pages — easier to share, bookmark and find.

  • New Data reference tables added to the big tools

    All 161 research nodes, all 49 tank mods and the full 7-day calendar cycle are now visible as static reference tables — useful as a printable cheat sheet or quick lookup. Intro guides also added above every interactive tool.

    Old links like /discord, /account, /bcem, /fire and /research now redirect automatically to the right page.

  • Perf Lighter pages, faster loads

    Affiliate content consolidated onto the donate page (removed from every other page). The scrolling "What's New" strip pauses when scrolled past to save battery.

  • New Urdu (اردو) language added

    The site is now available in 19 languages. Urdu joins the existing 18 and is fully written in Nastaliq (Arabic-derived) script, with game-specific terms (Last Z, Megahive, HQ, Boomer etc.) preserved in English by design. Switch language from the dropdown in the top-right.

  • Update Translations refreshed across all 19 languages

    Comprehensive audit and refresh of every translation file. All 19 languages now contain the same 3,230 content strings — including the new Glory Wars Megahive Rules (9-Point System) on the alliance pages.
