🚀 Major Improvements

📢 Read more about the new AI feature here

1. AI / LLM – core platform upgrades

• Support for multiple LLM providers CodeLite supports multiple LLM providers, such as "Ollama" & "Anthropic".
• Unified LLM manager – new LLMManager component with model‑listing, enable/disable helpers, interrupt support, and history handling.
• Endpoint wizard & multi‑model UI – a wizard for selecting the active provider, a drop‑down that persists the chosen model, and a “Clear history / Restart client” action.
• Extended AI‑powered features – code‑review, release‑note generation, doc‑string creation, function documentation, and automatic commit‑message suggestions.
• Server‑side improvements – timeout configuration (connect/read/write), automatic configuration reload on file‑save, and support for Ollama, Anthropic (Claude), DeepSeek and other providers.
• RAII helpers – FunctionsDisabler, EnableAllFunctions(), EnableFunctionByName() to safely toggle LLM features.

2. Language Server Protocol (LSP) enhancements

• Unified manager – LSP::Manager replaces the old LSPManager; all language‑server capabilities (completion, hover, go‑to‑definition/declaration, workspace symbols, semantic tokens, call‑tips, etc.) now go through a single entry point.
• Accelerated command handling – Find Symbol, Rename Symbol, Find References are grouped in a global accelerator group; per‑editor bindings removed.
• Selection‑aware navigation – “Go to Definition” now prefers the start of the current selection.
• Header lookup & workspace symbols – LSP::Manager::FindHeaderFile and WorkspaceSymbols provide direct server queries, replacing the legacy event‑based mechanisms.
• Semantic‑token driven theming – editor colours now update automatically from LSP semantic tokens.

3. Editor & UI modernisation

• Unified Outline View – Quick Outline replaced by a single Outline View with its own LSP document‑symbol event (wxEVT_LSP_DOCUMENT_SYMBOLS_OUTLINE_VIEW).
• Navigation bar enrichment – now shows classes, structs, enums, and interfaces as well as functions.
• Improved toolbars – all toolbars migrated to wxAuiToolBar; icons, accelerators and sash widths (250 px) refreshed.
• IndicatorPanel – reusable background‑task status widget used by both Git and ChatAI panels.
• Prompt editor & preview – PromptEditorDlg and TextGenerationPreviewFrame replace modal dialogs; markdown‑styled prompts, JSON parsing, and scroll‑resilience added.
• Platform‑native notebooks – Git “Changes” view now uses the native notebook widget on each OS (wxAuiNotebook, wxNativeBook, clGenericNotebook).

4. Git console and file‑tool upgrades

• AI‑driven Git tools – code‑review integration, release‑note generation button in the Git toolbar, and batch processing of commit logs.
• Enhanced log handling – FetchLogBetweenCommits splits logs into chunks, filters noise and returns a typed error object.

5. Configuration, build & platform support

• Centralised config APIs – CreateOrOpenConfig(), full validation, version checks and automatic backups for LLM settings.
• CMake modernisation – switched to add_compile_definitions, removed obsolete flags, and added hidden build‑directory layout (.build‑debug, .build‑release).
• Cross‑platform fixes – added OpenBSD support, updated third‑party submodules (assistant, ctagsd, dtl, libssh, yaml‑cpp), migrated many utilities to std::unique_ptr/std::optional, and replaced old typedefs with using.
• Documentation overhaul – README, download pages and ChatAI docs reorganised; badges, quick‑link tables and animated GIFs added.

6. Refactors & clean‑ups

• Consolidated XML utilities under XmlUtils.
• Moved string utilities to StringUtils.
• Replaced dead event bindings (wxEVT_CC_*, wxEVT_WXC_PROPETY_CHANGED, etc.).
• Applied modern C++ keywords (override, explicit, nullptr, [[maybe_unused]]).

🐞 Bug Fixes (consolidated)

• Typo & spelling corrections – hundreds of identifiers, comments and UI strings fixed (e.g., “behaviour → behavior”, “Parentesis → Parenthesis”).
• Comment‑detection logic – IsPositionInComment added; prevents completions and call‑tips inside comments.
• Status‑message timeout – reduced from 3 s to 1 s for doc‑string generation and LSP symbol requests.
• Duplicate/obsolete event removal – cleaned up wxEVT_CC_*, wxEVT_WXC_PROPETY_CHANGED, dead Outline‑view events, and dead LSP bindings.
• Crash & stability fixes – guard against null pointers in Git dialogs, Text Generation windows, LSP request handling, and remote workspace searches; fixed Linux‑specific crashes with wx3.2.
• Header‑lookup and workspace‑symbol bugs – resolved missing symbols, corrected file‑path handling (UTF‑8 conversions, proper quoting of paths with spaces).
• Build‑system issues – fixed missing includes (<memory>, <mutex>, <atomic>), corrected std::numeric_limits<size_t>::max() usage, and resolved GCC 15 and MSVC C++20 compilation errors.
• Git‑related fixes – improved log chunking, corrected toolbar bitmap handling, fixed rebase tool crashes, and restored missing “Add unstaged file” action.
• AI UI glitches – toolbar sizer flags, background‑task icon glitches, model‑selection dropdown resizing, and proper handling of empty model lists.
• Remote & SSH improvements – macro WorkspaceRealPath always resolved, safe deletion of custom SSH keys, and correct handling of special regex characters in remote searches.
• Miscellaneous – updated README badges, refreshed French localisation, removed unused headers, and applied consistent code‑formatting throughout the code base.
