## [Unreleased]
## [0.6.0] - 2026-01-16
### Added
- **Conflict Resolution System** - Git-style diff visualization for code review
- New `conflict.lua` module with full conflict management
- Git-style markers: `<<<<<<< CURRENT`, `=======`, `>>>>>>> INCOMING`
- Visual highlighting: green for original, blue for AI suggestions
- Buffer-local keymaps: `co` (ours), `ct` (theirs), `cb` (both), `cn` (none)
- Navigation keymaps: `]x` (next), `[x` (previous)
- Floating menu with `cm` or `<CR>` on conflict
- Number keys `1-4` for quick selection in menu
- Auto-show menu after code injection
- Auto-show menu for next conflict after resolution
- Commands: `:CoderConflictToggle`, `:CoderConflictMenu`, `:CoderConflictNext`, `:CoderConflictPrev`, `:CoderConflictStatus`, `:CoderConflictResolveAll`, `:CoderConflictAcceptCurrent`, `:CoderConflictAcceptIncoming`, `:CoderConflictAcceptBoth`, `:CoderConflictAcceptNone`, `:CoderConflictAutoMenu`
- **Linter Validation System** - Auto-check and fix lint errors after code injection
- New `linter.lua` module for LSP diagnostics integration
- Auto-saves file after code injection
- Waits for LSP diagnostics to update
- Detects errors and warnings in injected code region
- Auto-queues AI fix prompts for lint errors
- Shows errors in quickfix list
- Commands: `:CoderLintCheck`, `:CoderLintFix`, `:CoderLintQuickfix`, `:CoderLintToggleAuto`
- **SEARCH/REPLACE Block System** - Reliable code editing with fuzzy matching
- New `search_replace.lua` module for reliable code editing
- Parses SEARCH/REPLACE blocks from LLM responses
- Fuzzy matching with configurable thresholds
- Whitespace normalization for better matching
- Multiple matching strategies: exact, normalized, line-by-line
- Automatic fallback to line-based injection
- **Process and Show Menu Function** - Streamlined conflict handling
- New `process_and_show_menu()` function combines processing and menu display
- Ensures highlights and keymaps are set up before showing menu
### Changed
- Unified automatic and manual tag processing to use same code path
- `insert_conflict()` now only inserts markers, callers handle processing
- Added `nowait = true` to conflict keymaps to prevent delay from built-in `c` command
- Improved patch application flow with conflict mode integration
### Fixed
- Fixed `string.gsub` returning two values causing `table.insert` errors
- Fixed keymaps not triggering due to Neovim's `c` command intercepting first character
- Fixed menu not showing after code injection
- Fixed diff highlighting not appearing
---
## [0.5.0] - 2026-01-15
### Added
- **Cost Tracking System** - Track LLM API costs across sessions
- New `:CoderCost` command opens cost estimation floating window
- Session costs tracked in real-time
- All-time costs persisted in `.codetyper/cost_history.json`
- Per-model breakdown with token counts
- Pricing database for 50+ models (GPT-4/5, Claude, O-series, Gemini)
- Window keymaps: `q` close, `r` refresh, `c` clear session, `C` clear all
- **Automatic Ollama Fallback** - Graceful degradation when API limits hit
- Automatically switches to Ollama when Copilot rate limits exceeded
- Detects local Ollama availability before fallback
- Notifies user of provider switch
- **Enhanced Error Handling** - Better error messages for API failures
- Shows actual API response on parse errors
- Improved rate limit detection and messaging
- Sanitized newlines in error notifications
- **Agent Tools System Improvements**
- New `to_openai_format()` and `to_claude_format()` functions
- `get_definitions()` for generic tool access
- Fixed tool call argument serialization
- **Credentials Management System** - Store API keys outside of config files
- New `:CoderAddApiKey` command for interactive credential setup
- `:CoderRemoveApiKey` to remove stored credentials
- `:CoderCredentials` to view credential status
- `:CoderSwitchProvider` to switch active LLM provider
- Credentials stored in `~/.local/share/nvim/codetyper/configuration.json`
### Changed
- Cost window now shows both session and all-time statistics
- Improved agent prompt templates with correct tool names
- Better error context in LLM provider responses
### Fixed
- Fixed "Failed to parse Copilot response" error showing instead of actual error
- Fixed `nvim_buf_set_lines` crash from newlines in error messages
- Fixed `tools.definitions` nil error in agent initialization
- Fixed tool name mismatch in agent prompts
---
## [0.4.0] - 2026-01-13
### Added
- **Event-Driven Architecture** - Complete rewrite of prompt processing system
- Prompts are now treated as events with metadata
- New modules: `queue.lua`, `patch.lua`, `confidence.lua`, `worker.lua`, `scheduler.lua`
- Priority-based event queue with observer pattern
- Buffer snapshots for staleness detection
- **Optimistic Execution** - Ollama as fast local scout
- Use Ollama for first attempt (fast local inference)
- Automatically escalate to remote LLM if confidence is low
- Configurable escalation threshold (default: 0.7)
- **Confidence Scoring** - Response quality heuristics
- 5 weighted heuristics: length, uncertainty, syntax, repetition, truncation
- Scores range from 0.0-1.0
- Determines whether to escalate to more capable LLM
- **Staleness Detection** - Safe patch application
- Track `vim.b.changedtick` and content hash at prompt time
- Discard patches if buffer changed during generation
- **Completion-Aware Injection** - No fighting with autocomplete
- Defer code injection while completion popup visible
- Works with native popup, nvim-cmp, and coq_nvim
- **Tree-sitter Scope Resolution** - Smart context extraction
- Automatically resolves prompts to enclosing function/method/class
- Falls back to heuristics when Tree-sitter unavailable
- **Intent Detection** - Understands what you want
- Parses prompts to detect: complete, refactor, fix, add, document, test, optimize, explain
- Intent determines injection strategy
### Configuration
New `scheduler` configuration block:
```lua
scheduler = {
enabled = true,
ollama_scout = true,
escalation_threshold = 0.7,
max_concurrent = 2,
completion_delay_ms = 100,
}
```
