-----------------------------
v2.2.15 - 05/10/2026
-----------------------------

* Fixes

	- Reduced the home page size and response time: on every request the page was embedding the full geometry of all activations inline, a payload that keeps growing as more disasters and acquisitions are added; the map now loads only the markers it needs up front and fetches each activation's geometry when it is opened

-----------------------------
v2.2.14 - 28/09/2026
-----------------------------

* Fixes

	- Fixed progressive slowdown and socket timeouts caused by database connection pool exhaustion: during data ingestion the remote image and metadata downloads were performed while a database transaction was open, so a slow or unresponsive provider kept the connection in use for the whole download and eventually starved the pool; downloads now run before the transaction is opened, and a timeout was added so a stalled download can no longer hold up the ingestion

-----------------------------
v2.2.13 - 27/08/2026
-----------------------------

* Fixes

	- Fixed error when opening an activation whose call has no country assigned; missing countries are now handled gracefully
	- Reduced home page response times: client geolocation lookup now uses a shared HttpClient with a short timeout and caches failures, avoiding socket exhaustion under load
	- Acquisition/product image downloads are now validated to be real images; a provider returning an HTML login page (HTTP 200) is no longer stored as a quicklook, avoiding broken browse images on the map
	- Fixed SAR quicklooks (e.g. RADARSAT/RCM/TerraSAR-X) losing dark features such as rivers on the map: only the black border frame is now removed for radar imagery, preserving valid dark data (QL = 0); optical imagery is unchanged
	- Fixed intermittent HTTP 500 errors when COS2 ingestion coincided with concurrent page requests: database write operations no longer run on a separate thread, which could release the shared connection while another request was still using it (NullReferenceException in the data layer)

-----------------------------
v2.2.12 - 03/06/2026
-----------------------------

* Fixes

	- Fixed race condition on the satellites cache file (satellites.xml) causing intermittent HTTP 500 errors when COS2 ingestion and page requests accessed it at the same time
	- Access to satellites.xml is now serialized (atomic writes, shared reads) and the fallback read no longer throws on a transient lock

-----------------------------
v2.2.11 - 26/03/2026
-----------------------------

* Fixes

	- Fixed race condition causing HTTP 500 errors when COS2 data ingestion (disaster/product) coincides with concurrent page requests
	- Translation cache is now thread-safe: GetLanguages() uses double-checked locking to prevent concurrent initialization
	- TranslateModel() now takes a snapshot of the languages list before iterating to avoid InvalidOperationException
	- GetTranslatedValue() handles concurrent modifications by returning fallback values instead of crashing
	- AddModelTranslations() now invalidates the translations cache after modification to ensure clean state
