Neovim 0.10.0 Update Breaks Highlight Groups

[GophUndMe]

With the new update to Neovim, 0.10.0, some changes to highlighting groups have caused colors to switch roles, some to turn completely white, etc.

I've personally seen this while using Golang highlighting, both with and without Treesitter.

The related patch notes can be found here:

These Nvim specific highlight groups are now defined in a meaningfully different way and might need an update:
[hl-FloatBorder](https://neovim.io/doc/user/syntax.html#hl-FloatBorder) is linked to [hl-NormalFloat](https://neovim.io/doc/user/syntax.html#hl-NormalFloat) instead of [hl-WinSeparator](https://neovim.io/doc/user/syntax.html#hl-WinSeparator).
[hl-NormalFloat](https://neovim.io/doc/user/syntax.html#hl-NormalFloat) is not linked to [hl-Pmenu](https://neovim.io/doc/user/syntax.html#hl-Pmenu).
[hl-WinBar](https://neovim.io/doc/user/syntax.html#hl-WinBar) has different background.
[hl-WinBarNC](https://neovim.io/doc/user/syntax.html#hl-WinBarNC) is similar to [hl-WinBar](https://neovim.io/doc/user/syntax.html#hl-WinBar) but not bold.
[hl-WinSeparator](https://neovim.io/doc/user/syntax.html#hl-WinSeparator) is linked to [hl-Normal](https://neovim.io/doc/user/syntax.html#hl-Normal) instead of [hl-VertSplit](https://neovim.io/doc/user/deprecated.html#hl-VertSplit).
This also might result into some color schemes looking differently due to them relying on implicit assumptions about how highlight groups are defined by default. To account for this, define all attributes of highlight groups explicitly. Alternatively, use :colorscheme vim or :source $VIMRUNTIME/colors/vim.lua to restore previous definitions.

There's a work-around listed, but it doesn't seem to have any effect for me. A fixing update would be appreciated!

Hi, thanks for reporting. Could you be a bit more specific about the issues you're experiencing? There's an issue with golang? any other languages you've had issues with? The changenotes for neovim doesn't indicate it should mess with highlight groups.

Anyone who can shed some more light on this? I don't have the issues reported, but there are other colorschemes having the same issue

They mention a workaround for legacy schemes, but I need to be able to reproduce somehow
