# 0.25.0 [2020-09-09]
- Update to `yamux-0.8.0`. Upgrade step 4 of 4. This version always implements
the additive meaning w.r.t. initial window updates. The configuration option
`lazy_open` is removed. Yamux will automatically send an initial window update
if the receive window is configured to be larger than the default.
# 0.24.0 [2020-09-09]
- Update to `yamux-0.7.0`. Upgrade step 3 of 4. This version sets the flag but will
always interpret initial window updates as additive.
# 0.23.0 [2020-09-09]
- Update to `yamux-0.6.0`. As explain below, this is step 2 of 4 in a multi-release
upgrade. This version recognises and sets the flag that causes the new semantics
for the initial window update.
# 0.22.0 [2020-09-09]
- Update to `yamux-0.5.0`. *This is the start of a multi-release transition* to a
different behaviour w.r.t. the initial window update frame. Tracked in [[1]],
this will change the initial window update to mean "in addition to the default
receive window" rather than "the total receive window". This version recognises
a temporary flag, that will cause the new meaning. The next version `0.23.0`
will also set the flag. Version `0.24.0` will still set the flag but will always
implement the new meaning, and (finally) version `0.25.0` will no longer set the
flag and always use the additive semantics. If current code uses the default
Yamux configuration, all upgrades need to be performed in order because each
version is only compatible with its immediate predecessor. Alternatively, if the
default configuration is deployed with `lazy_open` set to `true`, one can
directly upgrade from version `0.21.0` to `0.25.0` without any intermediate
upgrades.
