How to read a Telegram build number
Desktop uses a three-part mark such as 6.2.3 — major, minor, patch. Android 10.14.2 follows the same idea on a different clock. Web has no package to compare; iOS hides the number inside the App Store listing. If two clients disagree, trust the sheet for the machine in your hand, not a screenshot from a different lane.
| Lane | Mark | What it means |
|---|---|---|
| Windows Desktop | 6.2.3 | Installer revision on the Windows sheet. A new exe replaces the previous setup; chats stay on the account. |
| Android APK | 10.14.2 | Package number on the Android sheet. Same signature upgrades in place; a mismatch forces an uninstall first. |
| Web | Browser | No local version file. The tab serves the current web client. Sign out on a shared PC after the errand. |
| macOS | Menu Bar | Revisions land from the in-app menu after you drop the app in Applications. Spotlight should not find a stale Downloads copy. |
| iOS | App Store | Apple’s listing owns the number. Update Telegram through the store, not a random IPA. |
When to replace a Telegram installer
A safe interval between Telegram updates is “when the client offers one,” not a weekly hunt for a newer exe. Replace the installer if the file never finished, an antivirus quarantined a half-write, or the signature no longer matches. Cloud chats return after login; a secret chat does not ride along with a reinstall.
Update cadence for Telegram clients
Desktop and Mac apply a revision after a restart. Android upgrades the APK in place when the signature matches. iOS waits on the store. Web refreshes with the tab. The handbook covers the first night; the hub is still the map before any button.
