 # styler 1.10.0
 
-**Infrastructure**
+This release contains speed-ups between 20% and 40% depending on your use case
+thanks to replacing {base} functionality with {vctrs} (#1114). With the speed
+boost introduced in version 1.8.0 in Oct. 2022, {styler} is now up to 2x as fast
+as before release 1.8.0.
 
-- Bump `actions/checkout` to version 3 in GitHub Actions (#1098).
-- Bump {touchstone} config (#1104, #1107).
-- split `test-public_api.R` for better sharding (#1109).
-- 0-pad filenames for sharding (#1110)
-- add missing {testthat} snapshots (#1115).
+This release was created upon a request by the CRAN team to actively manage not
+just cached files but also the potentially empty cache directories they live in
+(#1118). Here are the changes in detail:
 
-**Other changes**
