VERSIONHISTORY
Game updates, patches & platform versions
About this version log
This is a live record of every Arknights: Endfield version release, including download size, on-disk size, patch deltas, and per-platform resource versions for Windows, Android, iOS, and PlayStation. Data is auto-synced from the open-source ak-endfield-api-archive, which pulls directly from Hypergryph's official CDN, so timing reflects what actually shipped, not what was announced.
Use this page to plan downloads (patch days can hit a few GB), to check whether a cross-platform asset rollout has reached your platform, or to look up which version introduced a specific feature. The launcher version is tracked separately because launcher updates are not always coupled to game-data updates. Click any version entry in the timeline to see the platform-by-platform resource breakdown for that release.

How to Use the Version History
The page reads top to bottom, newest first. The Current Version card at the top shows the latest build, its release date, the full download size, the installed size, and the patch size when one exists. Below it, the Release Timeline lists every tracked build, currently 8, running from v1.0.13 on January 22, 2026 to v1.4.5. The Launcher Info panel at the bottom shows the launcher version and the date the data last synced.
Each timeline card has the same layout, so once you can read one you can read them all. The version number and release date sit on the left, and the download and installed sizes sit on the right. If a patch exists, a line underneath shows its size and which version it patches from. The row of tags at the bottom lists the resource version each platform received for that build.
Most players come here for one of three reasons. You want to know how big the next download will be, you want to check whether your platform has the same build as everyone else, or you want to date a change to a specific version. The sections below cover how to read each part of the data for those jobs.
Reading Download, Installed, and Patch Sizes
Three sizes appear on every entry, and they answer different questions. Download is the packed size, meaning the compressed bundles a fresh install pulls over the network. Installed is the unpacked size, meaning the space the game takes on disk after extraction. For the current build, that is 49.70 GiB to download and 54.66 GiB installed, so plan storage around the larger number.
The patch size matters more if you already have the game installed. It shows the delta update from the version named on that line, and it can be far smaller than a full download. The gap between v1.0.13 and v1.0.14 was a 253.81 MiB patch, while the move from v1.0.14 to v1.1.9 was a 35.55 GiB patch. A small point release can cost a few hundred megabytes, while a jump to a new major version can approach the size of a full install.
Note that the "patch from" version is not always the build directly before it. The archive records the delta from a specific earlier version, so a recent entry may list a patch from a build several versions back. Read that line as "coming from this version, expect this download," and use it as a rough guide if you are updating from somewhere else.
What the Platform Resource Versions Mean
The colored tags under each entry show the resource version for Windows, Android, iOS, and PlayStation. A resource version identifies the exact asset bundle a platform loaded. The archive stores it as a longer string, and the page trims it to the part that follows "main_" to keep the tags readable. Two platforms with the same tag are running the same assets for that build.
Tags often differ between platforms on the same version. On v1.4.5, Windows, Android, and PlayStation share 8692565-6 while iOS shows 8692565-11, and older builds show similar splits. Each platform ships through its own store process, so platforms can be briefly out of step during a rollout. If a friend on another platform sees content you do not, compare your tags here first.
The launcher version is tracked on its own because launcher updates are not always coupled to game-data updates. You will find it in the Launcher Info panel, currently v1.5.0, next to the date the data last synced. If you are troubleshooting a PC install, check both numbers, since a launcher update can land without a new game version and the reverse is also true.
Using the Timeline Alongside Patch Notes
The timeline tells you when a build shipped, not what was in it. The data comes from the open-source ak-endfield-api-archive, which pulls from Hypergryph's CDN, so the dates reflect what actually shipped rather than announcement dates. That makes it a reliable anchor when you are trying to pin down exactly when something changed.
For content, pair it with the site's other trackers. The patch notes page covers what each update changed, and the banner history shows which operators and weapons ran in each period. Match a release date here to an entry there and you can tell which build introduced a banner or a balance change.
For planning ahead, the timeline is also a quick way to see the gap between versions. Look at the dates between major builds to get a sense of pacing, then use the pull income sheet to estimate how much currency you will earn before the next one. When a large patch is coming, clear storage in advance so the update does not fail partway through.
Frequently Asked Questions
How often does Arknights: Endfield release new versions?
Major versions land roughly every 6 weeks, following Hypergryph's standard patch cadence inherited from Arknights mobile. Each major version (e.g., 1.1, 1.2) introduces a new story chapter, two limited operator banners, a major event, and balance changes. Minor patches (1.2.1, 1.2.2) ship every 1–2 weeks within a major version to push hotfixes, smaller events, and content additions. Resource-only updates (no client patch) happen even more frequently, sometimes weekly, for daily event rotations and store updates.
Why are there separate platform resource versions?
Each platform (Windows, Android, iOS, PlayStation) ships independently because each platform has its own store certification timeline. Windows and Android usually update first because they use server-driven hot patches; iOS waits on App Store review (usually 12–48 hours); PlayStation goes through Sony certification which can take several days. The 'resource version' string identifies the exact asset bundle each platform has loaded, players on the same major version but different platforms may briefly have mismatched assets during a rollout.
What is the difference between packed size and unpacked size?
Packed size is the download, what your device pulls over the network as compressed asset bundles. Unpacked size is the storage cost after the client extracts and processes the bundles into runtime form. The ratio is typically 1.5x–2x, so a 4GB download can use 8GB on disk. Patch sizes are usually packed only because patches deliver delta updates that decompress in place. Always have headroom equal to packed + unpacked size before starting a major update, otherwise the install fails midway.
Can I downgrade to an earlier version?
Not officially. Arknights: Endfield is a live-service game with server-side authority. Your account state expects the current version's game data, so an older client would refuse to connect to the live servers. Even archived APK builds from the source data archive cannot be used to play; they exist for data preservation and reverse engineering, not gameplay. If a new patch introduces a bug that breaks your build, the only fix is to wait for a hotfix; rolling back is not a supported recovery path.
Where does the version data come from?
Version history is sourced from the open-source ak-endfield-api-archive project by daydreamer-json, which scrapes the official Hypergryph CDN endpoints and version manifests at regular intervals. Because the data comes directly from the game's own update infrastructure, it reflects actual release timing, not announcement timing or community speculation. The archive also captures cross-platform resource versions, patch deltas, and launcher build numbers, so you can see exactly what shipped to which platform when.
