 ## [Unreleased]
 
+## [2021-05-07]
+
+### Added
+- Color export in comma-separated format
+- `\ur{...}` escape in `l3regex` to compose regexes
+- `\seq_set_split_keep_spaces:Nnn` (see #784)
+- `\seq_set_item:Nnn(TF)` and `\seq_pop_item:NnN(TF)`
+- `\box_ht_plus_dp:N` (issue #899)
+- `\clist_map_tokens:nn`, `\clist_map_tokens:Nn`,
+  `\str_map_tokens:nn`, `\str_map_tokens:Nn`
+
+### Changed
+- Use prevailing catcodes instead of string in regex replacement (issue #621)
+  (*Breaking change*)
+- `\__kernel_file_name_sanitize:n` now uses a faster `\csname`-based
+  approach to expand the file name
+- Improved performance for basic conditionals
+- `\pdf_version_gset:n` support for `dvips`
+- Improve handling of `\exp_not:n` in `\text_expand:n` (issue #875)
+- `\file_full_name:n` now avoids calling `\pdffilesize` primitive multiple times
+  on the same file
+- Show printable characters explicitly in `\regex_show:n`
+- Regex replacement now errors when using a submatch (`\1` etc) for which
+  the regex has too few groups
+- Showing complex datatypes now validates their internal structure (issue #884)
+- Indexing in l3doc: all page references before codeline references,
+  improve target placement, solve pdfTeX and makeindex warnings
+
+### Fixed
+- Evalutate integer constants only once (issue #861)
+- Detect `\ior_map_inline:Nn` calls on undefined streams (issue #194)
+
+### Deprecated
+- `l3docstrip` converted to a stub which simply loads DocStrip: use
+   the latter directly
