## [1.0.0] - 2025-10-31
9+
10+
### Breaking Changes
11+
12+
- **Renamed `@prefix` to `@action_prefix` in reducer modules**
13+
- All reducer modules must now use `@action_prefix` instead of `@prefix`
14+
- The `@action_prefix` can be `nil` or `""` to create catch-all reducers that handle all actions
15+
- Migration: Simply rename `@prefix` to `@action_prefix` in your reducer modules
16+
- Example:
17+
```elixir
18+
# Before (v0.x)
19+
defmodule MyReducer do
20+
use Phoenix.SessionProcess, :reducer
21+
@name :my_reducer
22+
@prefix "my" # Old name
23+
end
24+
25+
# After (v1.0.0)
26+
defmodule MyReducer do
27+
use Phoenix.SessionProcess, :reducer
28+
@name :my_reducer
29+
@action_prefix "my" # New name
30+
end
31+
```
32+
33+
- **Changed `dispatch/3` and `dispatch_async/3` return values**
34+
- Both functions now return `:ok` instead of `{:ok, new_state}`
35+
- All dispatches are now async (fire-and-forget) by default
36+
- Use `get_state/1-2` to retrieve state after dispatch
37+
- Migration:
38+
```elixir
39+
# Before (v0.x)
40+
{:ok, new_state} = SessionProcess.dispatch(session_id, :increment)
41+
IO.inspect(new_state)
42+
43+
# After (v1.0.0)
44+
:ok = SessionProcess.dispatch(session_id, :increment)
45+
new_state = SessionProcess.get_state(session_id)
46+
IO.inspect(new_state)
47+
```
48+
49+
- **Removed deprecated `Phoenix.SessionProcess.Redux` module**
50+
- The old struct-based Redux API has been removed
51+
- Use the Redux Store API (built into SessionProcess) instead
52+
- See migration guide: `REDUX_TO_SESSIONPROCESS_MIGRATION.md`
53+
54+
- **Action prefix stripping in reducers**
55+
- Reducers with `@action_prefix` now receive action types with the prefix stripped
56+
- When a reducer has `@action_prefix "counter"`, `handle_action` receives `"increment"` instead of `"counter.increment"`
57+
- Dispatch calls still use full prefixed names (e.g., `dispatch(id, "counter.increment")`)
58+
- Catch-all reducers (prefix `nil` or `""`) receive unchanged action types
59+
- Migration:
60+
```elixir
61+
# Before (v0.x)
62+
defmodule CounterReducer do
63+
use Phoenix.SessionProcess, :reducer
64+
@name :counter
65+
@action_prefix "counter"
66+
67+
def handle_action(%Action{type: "counter.increment"}, state) do
68+
%{state | count: state.count + 1}
69+
end
70+
end
71+
72+
# After (v1.0.0)
73+
defmodule CounterReducer do
74+
use Phoenix.SessionProcess, :reducer
75+
@name :counter
76+
@action_prefix "counter"
77+
78+
def handle_action(%Action{type: "increment"}, state) do
79+
%{state | count: state.count + 1}
80+
end
81+
end
82+
83+
# Dispatch calls remain unchanged
84+
dispatch(session_id, "counter.increment")
85+
```
86+
87+
### Added
88+
89+
- **`dispatch_async/3` function for explicit async dispatch**
90+
- Same behavior as `dispatch/3` but with clearer naming for async operations
91+
- Makes code intent more explicit when dispatching async actions
92+
- Example: `:ok = SessionProcess.dispatch_async(session_id, :increment)`
93+
94+
### Changed
95+
96+
- **Improved action routing with `@action_prefix`**
97+
- More consistent naming aligns with action routing semantics
98+
- Catch-all reducers now explicitly use `nil` or `""` for `@action_prefix`
99+
- Better documentation and examples for action routing
100+
101+
### Migration Guide
102+
103+
1. **Rename `@prefix` to `@action_prefix` in all reducer modules**
104+
- Search your codebase for `@prefix` in reducer modules
105+
- Replace with `@action_prefix`
106+
- No logic changes required
107+
108+
2. **Update action type patterns in handle_action/handle_async**
109+
- Remove the prefix from action type patterns
110+
- Example: `"counter.increment"` becomes `"increment"`
111+
- Dispatch calls remain unchanged (still use full prefixed names)
112+
- Only affects reducers with non-nil/non-empty `@action_prefix`
113+
114+
3. **Update dispatch call sites to handle `:ok` return value**
115+
- Replace `{:ok, state} = dispatch(...)` with `:ok = dispatch(...)`
116+
- Add `get_state(session_id)` calls where you need the updated state
117+
- Consider: Do you actually need the state? Many dispatches are fire-and-forget
118+
119+
4. **Remove uses of deprecated Redux module**
120+
- If using `Phoenix.SessionProcess.Redux` struct-based API
121+
- Migrate to Redux Store API (SessionProcess IS the store)
122+
- See `REDUX_TO_SESSIONPROCESS_MIGRATION.md` for detailed migration
123+
124+
### Notes
125+
126+
- All changes are breaking but migrations are straightforward
127+
- Most codebases will only need to rename `@prefix` to `@action_prefix`
128+
- Dispatch return value change makes async nature more explicit
129+
- v0.9.x will be the last version supporting deprecated APIs
130+
131+
## [0.6.0] - 2025-10-29
132+
133+
### Added
134+
- **Redux Store API**: SessionProcess now IS the Redux store - no separate Redux struct needed
135+
- `Phoenix.SessionProcess.dispatch/3` - Dispatch actions synchronously or asynchronously
136+
- `Phoenix.SessionProcess.subscribe/4` - Subscribe to state changes with optional selectors
137+
- `Phoenix.SessionProcess.unsubscribe/2` - Remove subscriptions
138+
- `Phoenix.SessionProcess.register_reducer/3` - Register named reducers
139+
- `Phoenix.SessionProcess.register_selector/3` - Register named selectors
140+

141+
- `Phoenix.SessionProcess.select/2` - Apply registered selector to current state
142+
- `user_init/1` callback for defining initial Redux state
143+
- **Enhanced LiveView Integration**: New helpers for Redux Store API
144+
- `Phoenix.SessionProcess.LiveView.mount_store/4` - Mount with direct SessionProcess subscriptions
145+
- `Phoenix.SessionProcess.LiveView.unmount_store/1` - Clean up subscriptions (optional, automatic cleanup via monitoring)
146+
- `Phoenix.SessionProcess.LiveView.dispatch_store/3` - Dispatch actions with sync/async options
147+
- **Selector-Based Subscriptions**: Only receive updates when selected state changes
148+

149+
- Memoized selector support
150+
- Automatic equality checking to prevent unnecessary notifications
151+
- **Process Monitoring**: Automatic subscription cleanup when LiveView processes terminate
152+

154+
- `REDUX_TO_SESSIONPROCESS_MIGRATION.md` - Detailed migration guide
155+
- `examples/liveview_redux_store_example.ex` - Complete working example (400+ lines)
156+
- Updated CLAUDE.md with comprehensive Redux Store API documentation
157+
158+
### Changed
159+
- **70% Less Boilerplate**: Simplified API eliminates manual Redux struct management
160+
- **Simpler Architecture**: SessionProcess handles Redux infrastructure internally
161+
- **Better Performance**: Selector-based updates reduce unnecessary state notifications
162+
- **Improved DX**: Clearer code intent with less nesting and fewer concepts
163+
164+
### Deprecated
165+
- `Phoenix.SessionProcess.Redux` module - Use Redux Store API instead
166+
- `Redux.init_state/2` - Use `user_init/1` callback
167+
- `Redux.dispatch/3` - Use `SessionProcess.dispatch/3`
168+
- `Redux.subscribe/3` - Use `SessionProcess.subscribe/4`
169+
- `Redux.get_state/1` - Use `SessionProcess.get_state/2`
170+
- `Phoenix.SessionProcess.LiveView` old API - Use new Redux Store API
171+
- `mount_session/4` - Use `mount_store/4`
172+
- `unmount_session/1` - Use `unmount_store/1`
173+
- **Migration Timeline**: Deprecated APIs will be removed in v1.0.0 (supported through v0.9.x)
174+
175+
### Migration
176+
- All old code continues to work with deprecation warnings
177+
- See `MIGRATION_GUIDE.md` for quick 2-step migration
178+
- See `REDUX_TO_SESSIONPROCESS_MIGRATION.md` for detailed examples
179+
- No breaking changes - 100% backward compatible
