Release notes

athena.2.0 (after athena.1.0)

Changes:

• The planning controls of zora.4: interaction modes (browse, select, create, move) with keyboard shortcuts, selecting blocks, resizing blocks, dropping a block on another item, child rows nested to any depth, and the time while creating, moving and resizing blocks
• ./alan upgrade converts a webclient system from athena.1.0, zora.4.0 and zora.3.0

Before the upgrade

Nothing.

After the upgrade

• From athena.1.0 the syntax is unchanged.
• From zora.4.0 and zora.3.0 the upgrade converts the query headers in views/*.alan. The widget changes of athena.1.0 are not converted; change them as described in the release notes of athena.1.0, fixing what the build reports, topmost error first:
  • A query binding in a widget expression names its query without candidates. The build reports the old form with unexpected keyword `candidates` while making a decision for stategroup 'type' of !'widget expression tail'.'type'?'binding':

// old
'options candidates' = :: query candidates 'choose shift' (

// new
'options candidates' = :: query 'choose shift' (

• Reading the 'todo' stategroup of the client bindings requires a 'state' binding. The build reports a read on the node with 'state group' `todo` was not found in 'properties':

// old, inside a state binding
switch ^ $ [ /'node'.'todo'?'yes'.'active'?'yes'] (

// new
switch ^ $ [ .'todo'?'yes'.'active'?'yes'] (
