## Changelog

### 0.2

- Usernames that are not readable channels are now told apart: no such username (`notFound`), a user, bot or group (`notAChannel`), and a channel with the web preview disabled (`previewUnavailable`). Previously every one of them was reported as a channel with its preview disabled.
- Growth history is saved right after a channel row is delivered, so a run that stops later no longer counts the same channel as new next time.
- The billed-rows count in the run message no longer includes rows that were not charged.

### 0.1

- First release: one analytics row per public Telegram channel (subscribers, view rate, cadence, reactions, forwards) and growth since the previous run.
- Tested inputs: three channels of different size (typical), a username without a public preview and one that does not exist (status rows), a subscriber filter that excludes every channel (single status row).
