# Migrating from 9.0 to 10.0

To upgrade your Handsontable version from 9.0.x to 10.0.x, follow this guide.

# Step 1: Rename your hooks

If you use the beforeRender or afterRender hooks, update their names in your app (#8632 (opens new window)).

Before After
beforeRender beforeViewRender
afterRender afterViewRender

There are still hooks that are named beforeRender and afterRender, but they do completely new things now. For more details, see the Handsontable 10.0 API reference:

# Step 2: Adapt to the HyperFormula dependency update

In Handsontable 10.0.0, we updated the optional HyperFormula dependency from 0.6.2 to ^1.1.0 (#8669 (opens new window)).

For more details on the breaking changes between HyperFormula 0.6.x and HyperFormula 1.0.x, see the migration guide (opens new window).

# Step 3: Adapt to the configuration options' new default values

In Handsontable 10.0.0, we changed the default values of the autoWrapCol and autoWrapRow configuration options, from true to false (#8662 (opens new window)):

Before After
autoWrapCol: true autoWrapCol: false
autoWrapRow: true autoWrapRow: false

We also changed the default values for the rowsLimit and columnsLimit options of the CopyPaste plugin, from 1000 to Infinity (#8676 (opens new window)):

Before After
rowsLimit: 1000 rowsLimit: Infinity
columnsLimit: 1000 columnsLimit: Infinity

# Step 4: Adapt to the hook changes

In Handsontable 10.0, we unified the naming of an argument used by the beforeOnCellMouseDown and beforeOnCellMouseOver hooks (#8591 (opens new window)):

Hook Before After
beforeOnCellMouseDown blockCalculations controller
beforeOnCellMouseOver blockCalculations controller

In both cases, the renamed controller object now has a cell property, instead of a cells property:

blockCalculations (before) controller (after)
row
column
cells
row
column
cell

This change affects the following plugins:

# Step 5: Adapt to the font changes

To make Handsontable look good right out of the box, we added default font-family, font size, font weight, and color properties for all elements within the .handsontable CSS class (#8681 (opens new window)). If you're not overwriting these properties in your app, this change will affect your grid's font.
