[https://github.com/Automattic/vip-go-mu-plugins/pull/2019](https://github.com/Automattic/vip-go-mu-plugins/pull/2019) 09 March 2021 16:22:57 GMT+0000 [ VIP MU plugins [Production] ](https://docs.wpvip.com/changelog/vip-mu-plugins-production/) [ Permalink ](https://docs.wpvip.com/changelog/vip-mu-plugins-production/plugin-updated-akismet/) Update Akismet to 4.1.9 [https://github.com/Automattic/vip-go-mu-plugins/pull/2009](https://github.com/Automattic/vip-go-mu-plugins/pull/2009) 09 March 2021 16:22:52 GMT+0000 [ VIP MU plugins [Production] ](https://docs.wpvip.com/changelog/vip-mu-plugins-production/) [ Permalink ](https://docs.wpvip.com/changelog/vip-mu-plugins-production/handle-potential-race-conditions-around-notoptions/) There is a possibility in the core that if a notoptions are being updated at the same time, a change could be rewritten. This would then result in option being stored in DB but also marked as non-existing in notoptions making further attempts to add such option always fail without removing the options from the list of non- existing options. We have deployed a fix for this over a week ago but decided to do 2 phase deployment. The first phase was all non-prod environments. As we did not see any negative effects of this change we will roll it out to prod environments with this change. [https://github.com/Automattic/vip-go-mu-plugins/pull/2015](https://github.com/Automattic/vip-go-mu-plugins/pull/2015) 04 March 2021 23:28:56 GMT+0000 [ VIP MU plugins [Production] ](https://docs.wpvip.com/changelog/vip-mu-plugins-production/) [ Permalink ](https://docs.wpvip.com/changelog/vip-mu-plugins-production/plugin-updated-search-11/) In some cases hooks for setting per-site values for Search settings were not getting applied. By applying Search settings much later on the `after_setup_theme` hook, we make it much easier and more reliable to capture per-site settings.

This has been rectified. [https://github.com/Automattic/vip-go-mu-plugins/pull/1998](https://github.com/Automattic/vip-go-mu-plugins/pull/1998) 02 March 2021 19:37:24 GMT+0000 [ VIP MU plugins [Production] ](https://docs.wpvip.com/changelog/vip-mu-plugins-production/) [ Permalink ](https://docs.wpvip.com/changelog/vip-mu-plugins-production/plugin-updated-jetpack-9-5/) We have upgraded the Jetpack 9.5 subtree to contain the final Jetpack 9.5 release. This will be set as the default for all unpinned sites on Thursday 4th. [https://github.com/Automattic/vip-go-mu-plugins/pull/2008](https://github.com/Automattic/vip-go-mu-plugins/pull/2008) 02 March 2021 19:37:21 GMT+0000 [ VIP MU plugins [Production] ](https://docs.wpvip.com/changelog/vip-mu-plugins-production/) [ Permalink ](https://docs.wpvip.com/changelog/vip-mu-plugins-production/plugin-updated-search-10/) This change enables compression on HTTP requests towards Elasticsearch.
