v0.13.4

Adds experimental (unstable) feature: sender-side message batching.

• mergeMessages function
• WebSocketNetwork batchSendMS option

v0.13.3

• WebSocketNetwork: always deliver updates in causal order, so that it can be used with CRuntime's causalityGuaranteed option.

v0.13.2

• Fix ws-server InMemoryDocStore bug that caused too many checkpoint requests
• Add CRuntime.batchRemoteUpdates method that lets you avoid unnecessary renders (specifically, change events), and use it in the load/welcome step of network providers
• Add ws-client batchRemoteMS option (in subscribe) that batches remote updates
• Use above feature in rich-text demo to deliver Quill updates only once per 50 ms. This is important in large groups, where delivering updates to Quill becomes the bottleneck.
• collabs-ws-server command: input HOST instead of HOSTNAME

v0.13.1

This release adds network and storage providers and React hooks. It also removes containers.

New packages:

• @collabs/indexeddb
• @collabs/local-storage
• @collabs/tab-sync
• @collabs/react

Revamped packages:

• @collabs/ws-client
• @collabs/ws-server
  These are now more reasonable, e.g., storing doc states and allowing you to authenticate clients.

Deleted packages:

• @collabs/container
• @collabs/container-testing-server

Other breaking changes:

• @collabs/collabs: Refactored CRuntime events, and renamed RuntimeEventsRecord -> DocEventsRecord, RuntimeOptions -> DocOptions.

Misc:

• Revised https://collabs.readthedocs.io/en/latest/ (in particular, its description of documents) and added descriptions of the new packages.
• Added a Recipe Editor demo that uses @collabs/react.
• Moved templates to their own repos: https://github.com/composablesys/collabs-template-app , https://github.com/composablesys/collabs-template-crdt

This is almost a 1.0 "beta" release; before that, I mainly intend to work on rich-text editor integrations.

v0.12.0

This release cleans up the project internals and some APIs. After this release, I have no more planned breaking API changes in @collabs/collabs except for small tweaks to CRichText and some list internals.

Breaking changes:

• CVar and CBoolean now emit a "Set" event every time they receive an operation, even if it does not change the value.
• Remove some list utility methods (e.g. CValueList.concat).
• Change the order of list entries() methods' outputs: [index, value, position] instead of [index, position, value]. Likewise for CRichText.entries().
• Change CRichText's default iterator to use formatted() instead of entries().
• Remove CMap.getConflicts().
• Remove runtime nextUID() and nextLocalCounter() utility methods.
• Remove Bytes class. Instead, use base64-js.
• Change some optional params to options objects (Collab.emit, TestingRuntimes.newRuntime).

Other API/behavior changes:

• splice and indexOf now handle out-of-range indices like their Array analogs.
• Make CValueSet.delete's return value match the built-in Set. Likewise for CValueMap.
• CList now emits additional events concerning archived values. These should be sufficient to let you maintain a local view of the archived values and their positions.
• Add AbstractDoc versions of CRuntime utility methods (fromID, idOf, replicaID).
• MultiValueMap.get now defensively copies internal arrays before returning.

v0.11.1

• Fix CRichText empty load bug

v0.11.0

New features:

• Shared presence, including shared cursors in Quill demo
• Cursor type and Cursors utils, for managing and sharing Cursors slightly more easily than with Position. See plaintext demo for example usage.

Misc changes:

• Name change: Plain Tree -> Fugue. The algorithm is unchanged.
• CList semantics change: use restore-wins for archive vs restore. This enables "keepalive" semantics like those from the paper A Study of Semantics for CRDT-based Collaborative Spreadsheets.

Alpha software - API subject to change.

v0.10.2

Bug fix:

• Add Position import in 2nd abstract_lists.d.ts (caused an error when compiling a Node project that imported @collabs/crdts)

v0.10.1

Bug fixes:

• Add Position import in abstract_lists.d.ts (caused an error when compiling a Node project that imported @collabs/core)
• Add missing dependency to the rich-text demo's package.json.

Alpha software - API subject to change.

v0.10.0

• Adds CRichText Collab implementing a rich-text string, based on the Peritext algorithm.
• Changes the library used by StringSerializer. This (somehow) reduces memory usage by 50% on our text benchmarks.
• Adds some CText utility methods.
