feat(api): nvim_echo(percent=nil) means "unknown" progress #39029

2026-04-24T15:57:35Z

Problem: No way to signal "unknown" or "indeterminate" progress percentage. Solution: Treat percent=nil as "indeterminate" percent.

fix(api): expose fg_indexed/bg_indexed in nvim_get_hl #39210

2026-04-20T09:12:52Z

Problem: fg_indexed/bg_indexed were dropped from nvim_get_hl output due to a wrong short_keys guard. HL_FG_INDEXED also wasn't cleared in hl_blend_attrs, and HLATTRS_DICT_SIZE was too small. Solution: Remove the short_keys guard, clear HL_FG_INDEXED in hl_blend_attrs, bump HLATTRS_DICT_SIZE to 24, and clarify docs that these flags mean rgb is an approximation of the cterm palette index.

fix(lsp): limit number of created highlight groups (#39133)

2026-04-18T00:16:11Z

* fix(api): allow silencing "Too many highlight groups" error Problem: Using Lua's `vim.api.nvim_set_hl(0, 'New', {...})` can fail if there are too many existing highlight groups. However, this error can not be silenced with `pcall`. Solution: Make it possible to silence in `nvim_set_hl` and `nvim_get_hl_id_by_name`. * fix(lsp): limit number of groups created by `document_color()` Problem: A file can contain many string colors that would be highlighted by an LSP server. If this number crosses 19999 (maximum number of allowed highlight groups), there are general issues with creating other highlight groups, which can break functionality outside of `vim.lsp.document_color`. Solution: Limit number of highlight groups that are created by `vim.lsp.document_color` to 10000 (half of allowed maximum). This is not a 100% solution (since there can exist more than 10000 other highlight groups), but explicitly checking number of groups is slow and 10000 should (hopefully) be enough for most use cases.

fix(terminal): forward streamed bracketed paste properly (#39152)

refactor(api): rename "window" to "win" (positional parameters) #39083

2026-04-15T17:31:17Z

continues d0af4cd9094f. This commit renames positional parameters. This is only "cosmetic", but is intended to make it extra clear which name is preferred, since people often copy existing code despite the guidelines in `:help dev-naming`.

refactor(api): rename buffer to buf (positional parameters) #39013

2026-04-15T13:48:21Z

In 3a4a66017b74, 4d3a67cd6201, df8d98173cbc we renamed "buffer" to "buf" in dict parameters and return-values. This commit renames positional parameters. This is only "cosmetic", but is intended to make it extra clear which name is preferred, since people often copy existing code despite the guidelines in `:help dev-naming`.

feat(api): rename buffer to buf in retval #38900

2026-04-13T16:42:26Z

In 3a4a66017b74192caaf9af9af172bdc08e0c1608, 4d3a67cd620152d11ab9b5f5bdd973f84cc2d44b we renamed "buffer" to "buf" in dict parameters. This commit also renames such keys in dict return-values.

feat(api): nvim_set_hl can set "font" #37668

2026-04-12T15:19:40Z

Problem: Cannot set highlight group fonts via API, only via :highlight command. Solution: Add font parameter in nvim_set_hl().
