Version 5.1.0

mobx-state-tree changes

Note from the maintainer: we are releasing a "feature-level" 5.x release due to mst-middlewares and mobx-state-tree versions being synchronized. However, mobx-state-tree does not have any significant changes in this release. We plan to decouple mst-middlewares and mobx-state-tree in the future to avoid this issue. Sorry about any issues this causes!

• Docs: Include Instance import in docs (#1834 by @hgulersen and @elektronik2k5)
• CI: Return coverage report (#1819 by @pustovalov)
• Minor refactors (#1800, #1801, #1802 by @rluvaton)

mst-middlewares changes

• Add includeHooks flag to UndoManager (#1796 by @andrezzoid)
• Update mobx-state-tree peerDependency in mst-middlewares (#1824 by @Tucker-Eric, @FreeFrags, and @ruudandriessen)

Version 5.0.5

This patch-level release fixes an issue with snapshots being preprocessed twice in some instances. Thanks to @adamkovalsky for the PR (#1822)!

• Fixes a regression introduced in #1792 where a snapshot preprocessor gets called on an already preprocessed snapshot, resulting in potential errors.

Version 5.0.4

This patch-level release fixes three issues with node reconciliation. Thanks to @adamkovalsky for the PR!

• Adds a getReconcilationType method to BaseNode, which returns the type which should be used for reconcilating the node. This is normally the node's type, but in the case of snapshotProcessor it is overridden to be the snapshotProcessor type. This is necessary so that the union type reconcile can correctly reconcile the "current" node first if it's possible. This fixes #1791.
• Fixes the snapshotProcessor type's isValidSnapshot and is methods to return a validation error and not to throw if the specified preprocessor fails, which can happen when checking if an arbitrary snapshot is valid input (e.g. when determining a union type). We can't expect preprocessors to accept any arbitrary input, so we must assume they can throw when provided with invalid snapshots. This also fixes #1777.
• Fixes the array's areSame utility to first check that the provided value is a valid snapshot before calling isMatchingSnapshotId, to avoid the preprocessor throwing an error if the provided snapshot is invalid.

Version 5.0.3

This patch-level release has a few small updates:

• Fixes array reconciliation in snapshotProcessor in #1784 by @adamkovalsky, fixing #1776
• Updates devDependencies across the project in #1786 by @jamonholmgren
• Some documentation updates as well
