###### New
- Simple HTTP API example (#530) by @briancaffey
- Command-line streaming inference example (#512) by @ZaymeShaw
- Batch Vocos decoding (generate matrix by longest token, fill the rest with 0) (6e18575) by @fumiama
- Adaptation to new VQ Encoder (9f0b7a0) by @fumiama
- ZeroShot support (b4da237) by @fumiama
- Initial support for vLLM (8e6184e) by @ylzz1997
- Added `--source` and `--custom_path` parameters to command-line examples (#669) by @weedge
- Added `inplace` parameter to `Speaker` class for fine-tuning (#679) by @ain-soph
- Added `experimental` parameter to `Chat.load` function (#682) by @ain-soph

###### Fixed
- Intermittent glitches in streaming inference audio (7ee5426) by @fumiama
- Different accent per generation even under the same parameters in WebUI (3edd47c) by @fumiama
- `normalizer` changed tag format, causing model to read out the tag (c6bae90) by @fumiama
- Replaced unaccessable GitCode mirror (c06f1d45) by @fumiama
- Error in handling repetition penalty idx (#738) by @niuzheng168

###### Optimized
- Completely removed `pretrain_models` dictionary (77c7e20) by @fumiama
- Made `tokenizer` a standalone class (77c7e20) by @fumiama
- `normalizer` will remove all unsupported characters now to avoid inference errors (0f47a87) by @fumiama
- Removed `config` folder, settings are now directly embedded into the code for easier changes (27331c3) by @fumiama
- Removed extra whitespace at the end of streaming inference (#564) by @Ox0400
- Added `manual_seed` parameter, which directly provides `generator` to `multinomial`, avoiding impact on torch environment (e675a59) by @fumiama
- `tokenizer` loading switched from `.pt` to the built-in `from_pretrained` method to eliminate potential malicious code loading (80b24e6) by @fumiama
- Made `speaker` class standalone, placing `spk_stat` related content within it, and directly wrote its values into the settings class due to its small size (f3dcd97) by @fumiama
- `Chat.load` will set `compile=False` now by default (7e33889) by @fumiama
- Switched GPT to `safetensor` model (8a503fd) by @fumiama

###### Dependencies
- Changed code license to open-source AGPL3.0 (9f402ba)

###### 新增
- 简单的 HTTP API 示例 (#530) by @briancaffey 
- 命令行流式推理实例 (#512) by @ZaymeShaw 
- 批量 Vocos 解码（按最长 token 生成矩阵，其余填0） (6e18575) by @fumiama 
- 适配新 VQ Encoder (9f0b7a0) by @fumiama 
- ZeroShot 支持 (b4da237) by @fumiama 
- 初步支持 vLLM (8e6184e) by @ylzz1997 
- 命令行示例增加`--source`和`--custom_path`参数 (#669) by @weedge 
- 为引入微调，给`Speaker`类增加`inplace`参数 (#679) by @ain-soph 
- 给`Chat.load`函数增加`experimental`参数 (#682) by @ain-soph 
###### 修复
- 流式推理的声音有间断性毛刺 (7ee5426) by @fumiama 
- WebUI 相同条件下音频生成每次不同 (3edd47c) by @fumiama 
- `normalizer`更改 tag 导致模型将 tag 读出 (c6bae90) by @fumiama 
- 更换已失效的 GitCode 镜像 (c06f1d45) by @fumiama 
- repetition penalty idx 处理错误 (#738) by @niuzheng168 
###### 优化
- 彻底移除`pretrain_models`字典 (77c7e20) by @fumiama 
- 将`tokenizer`独立为一个类 (77c7e20) by @fumiama 
- `normalizer`将所有不支持的字符删除以免推理出错 (0f47a87) by @fumiama 
- 取消`config`文件夹，直接把设置写入代码方便更改 (27331c3) by @fumiama 
- 删除流式推理末尾多余的空白 (#564) by @Ox0400 
- 在调用前设置`manual_seed`改为直接给`multinomial`提供`generator`，避免影响 torch 环境 (e675a59) by @fumiama 
- 将`tokenizer`从直接加载`.pt`改为调用自带的`from_pretrained`方法，从而消除可能的恶意代码加载 (80b24e6) by @fumiama 
- 独立`speaker`类，放置`spk_stat`相关内容，同时因为该模型很小，所以直接将它的值写入了设置类 (f3dcd97) by @fumiama 
- `Chat.load`参数改为默认关闭编译 (7e33889) by @fumiama 
- GPT 切换到`safetensor`模型 (8a503fd) by @fumiama 
###### 依赖
- 代码许可证更改为开源的 AGPL3.0 (9f402ba)
