v4.10.0

• A path an include names without wildcards stays against a wider
  exclude:. build/version.txt next to exclude: build/**, or src/.env
  next to exclude: '**/.*', is kept in sources and generates, as is a
  generates fingerprint: file; only an exclusion naming the same path removes
  it. A path named only by a task taken with from: or task: still follows
  the taking task's exclusions. Tasks whose exclude: used to remove such a
  path see their checksum change once.
• An exclude: matches dot entries. Its wildcards and ** also match
  names beginning with a dot, so exclude: dir/** removes everything an
  include lists under dir, hidden files included. Includes still list a dot
  entry only when its name is written out without wildcards. Only tasks whose
  wildcard includes list a dot entry inside an excluded tree see their checksum
  change, once. Tasks with a dot-file include elsewhere, such as
  web/.yarnrc.yml next to exclude: '**/node_modules/**', no longer scan the
  excluded trees, which could make them twice as slow.
• An exclude: removes every path its pattern matches, however an include
  reached it: through a symlink, a link back up, or a directory that can be
  searched but not read. exclude: a//b/** now excludes a/b/**, and
  exclude: link/** drops link when it is a symlink to a directory. Tasks
  with such paths see their checksum change once. Exclusions no longer walk
  the tree themselves, which speeds up patterns such as exclude: '**/*.pyc'.
• A task's own exclude: dir/** also keeps the sources and generates it
  takes from other tasks (task:, from:) from scanning dir. A task
  taking **/*.rs sources from another no longer scans the node_modules
  trees it excludes; the file lists are unchanged.
• A relative glob ending in / matches directories only, in sources,
  generates and sandbox.reads, as an absolute one already did: it lists a
  symlink to a directory, never a file. Before, sources: [build/] listed a
  file named build, exclude: build/ removed one, and exclude: dir/**/
  removed every file under dir. Tasks with such entries see their checksum
  change once.
