# Firenook 0.2.0-next.6 release notes > Firenook 0.2.0-next.6, 18 October 2026: a stop closes the data, a killed engine is no stop, saved data opens in milliseconds, and more. Data closed on stop, starts in milliseconds, the store's size. Published on 18 October 2026, as a preview. `npm install --save-dev firenook@0.2.0-next.6` [Every release](https://firenook.dev/changelog) A newer release is out: [Firenook 0.2.0](https://firenook.dev/changelog/0.2.0), the first release for public use. ## What changed 8 changes you will notice, as the release notes give them. 1. ### A stop closes the data Since 0.2.0-next.3 a stop left Firestore's store file marked open (and Storage's since 0.2.0-next.4), so every start after a stop repaired it first. The console's change feed, schema index and Overview count held the store they observed, Storage held a Firestore handle, and the console's whole-database walks ignored the stop. A stop once ready, or while starting, now closes Storage, then Firestore; one that cannot close a database is reported as a failed stop. 2. ### A killed engine is no stop The screen said "stopped … everything is kept" whenever a stop was asked for and the engine then ended, even by a kill. Now it says the stop did not finish and that the next start checks the data first; plain mode says the same in one line. 3. ### Saved data opens in milliseconds The documents' count is saved with every commit instead of decoding every document at each open: a 32.6 GB store of 2.7 million documents opened in 146 s and now in 67 ms, a 4.3 GB one in 1.4 s and now in 63 ms. The first start of data an earlier release wrote counts once and saves the result. 4. ### `firenook state:inspect --state-dir DIR` shows what a stopped store's file holds, table by table, and how much of it is free. 5. ### `firenook state:compact --state-dir DIR` returns a stopped store's free pages to the disk, copying the file first (a clone where the file system has one; `--no-copy` skips it). Every document stays as it is. On the 32.6 GB store: 32.60 GB to 27.79 GB in 16 minutes. 6. ### The console Overview's Firestore card shows the store's size on disk 7. ### The old documents table is cleared once its documents are copied to the current layout; stores first written before 0.1.0-next.3 carried a dead copy of every document. 8. ### Published straight to `latest` The release workflow can now publish the CLI to `latest` in its one trusted publish, and this release used it. npm sets one tag per publish, so the CLI's `next` stays on 0.2.0-next.5 until it is moved by hand, and a preview install, which follows `next`, is not told about this release until then. ## What got faster Measured on the same data with 0.2.0-next.5 and with 0.2.0-next.6. Lower is better. ### Opening saved data, 2.7 million documents 2,179× sooner - [0.2.0-next.5](https://firenook.dev/changelog/0.2.0-next.5) 146 s - [0.2.0-next.6](https://firenook.dev/changelog/0.2.0-next.6) 67 ms Every multiple is rounded down. [Every release’s measures](https://firenook.dev/changelog#faster). ## Your data What this release does to data an earlier one kept, and to the ports and protocols. - Data saved by 0.2.0-next.6 stays readable by 0.2.0-next.5: the count is a new entry the earlier release ignores. No emulator protocol or port changed. ## How it was checked The source it was built from, the runs it passed, and how it was published. - Pin the engine to `767605db4248fed403523a24f6901fcc1e693d13`, the merge of [PR #93](https://github.com/firenook-dev/firenook/pull/93) on 0.2.0-next.5.
